Embrace the advantages of compostables

Biowastes and similar biodegradable wastes are finally beginning to have their wider benefits recognised at a policy level.

These benefits, particularly those around carbon, can only be fully realised through their safe recycling back to soil. The fundamental question of how to collect has been answered – weekly separate collection – but the devil always lies in the detail and the questions now are much more nuanced. Their answers range from an understanding of systemic needs and benefits to ones of blinkered rhetoric which some might say deliberately miss the point. But what is that point exactly?

Resource strategy
Food and garden waste will become mandatory waste streams in England post 2023, but there is some concern that not enough focus is being put on the methodologies to ensure this biowaste is separately collected and treated. Above all, there is concern that the current practices that create high plastic contamination rates, which in the best case lead to increase processing costs but more often to low quality and polluting outputs, will continue and indeed rise. As food waste arisings entering treatment increase four or five fold, getting food waste collection and treatment right is vitally important to the whole resource strategy.

Compostables
Moreover, where compostable materials are concerned, we need to ensure these are used in the right applications and bring value to the system, avoiding cross-contamination and consumer confusion. Producers of compostable products already pay into PRN and future EPR schemes, but their “investments” are diverted away from their true destiny. These producers range from large multi-nationals to UK-based SMEs, and they all keen to have those payments contributing towards enhancing a system in which biowastes in general are valorised.

Compostables are often described as a carte blanche substitution to single use plastic packaging. This is looking down the telescope the wrong way. Compostables can indeed substitute plastic packaging, but only have sense when they can themselves drive food waste to composting and AD. This is our largest waste stream, the largest emitter of GHG in the waste sector, and one that requires significant investment in collection and treatment to get right.

Getting food waste into treatment properly means:

1. Simple to use and uniform across the country, to enable nationwide communications programmes and reduce procurement costs for councils;

2. With the least smell and fuss for consumers, so householders comply with the requirement to separately collect;

3. As much as possible. This means intercepting in the future as much as 100 kilos per inhabitant annually (two kilos a week) while working on food waste reduction targets too;

4. As cleanly as possible, so it can make gas and compost or digestate. This means with the least contamination possible, avoiding blockages and leaks of contaminants to soil;

5. With as much financial return as possible for the operators. In turn, this means least amount of contaminating waste to strip out and send to disposal, and the highest yields of gas and biofertilisers and composts possible;

6. With the best quality outputs possible so we can ensure a value driven marketplace for the compost and digestate produced.

Only by collecting biowastes with compostables can we ensure these objectives are reached. Plastics do not compost nor produce gas, and in organics are contaminants that should be collected for plastic recycling, not organics recycling. Compostable packaging, bin liners, carrier bags, bags, coffee pods, teabags, labels on fruit/vegetables, fruit and vegetable bags, magazine wraps and catering tableware can all be materials used to convey food waste to treatment where the packaging itself can biodegrade with the contents. This is the use of compostables – to enhance the production of biogas and biofertilisers and the reduction of contamination, and reduce plastic pollution in doing so.

Anaerobic digestion
We don’t want compostables contaminating plastics, although the statistical possibility is extremely low; similarly we don’t want plastics contaminating organics, as it does now – as much as 20% of all inputs to AD and compost are plastic packaging. So we need separate and clean streams. When there is cross contamination, technologies can sort it out, like the new plant opened by Jayplas shows.

AD operators attempt to strip out all packaging and indeed compostables too. But currently AD in the UK treats very only small amounts of household food waste – about 20% of what is coming along post 2023. The investments needed to treat those millions of extra tons can help the sector upgrade technologies and treat materials more efficiently, as many European and modern UK plants have demonstrated. This will also require an increase in scale of plants; today they are very small compared to what is needed.

If AD gets its head around recovering materials as well as biowaste, it is a win-win for the industry, cutting plastic waste, cutting disposal costs, improving yields, economic and environmental performance and producing new outputs like compost. To do this we need all food waste collected with one bag, compostable, so it can go either to IVC or AD. Counter-intuitively, this gives councils flexibility when collecting their food wastes – they are no longer tied to a specific treatment if all treatment accepts compostable bags.

Italy
The circularity of compostables is to be found in the circularity of food waste – as a vehicle to drive those biowastes to treatment cleanly, without plastic contamination. Has this been proven?

Take a look at the Italian case. Italy collects and treats two thirds of all the food waste collected and treated in the EU, including the UK and Norway. It has therefore a unique and exceptionally successful record. The Italians have plants treating 700,000, 550,000, 300,000 tons a year each – one plant in Milan treats more than all of England. Over 6 million tons of food waste is treated this year in Italy.

They banned the use of plastics in biowaste collections in 2010 and now have contamination rates of 1.5% plastics.

Compostable plastics are used for the collections but in many other uses such as fruit and vegetable bags, carrier bags, coffee pods, catering ware and so on. Data from their composting association shows that 80% of all the compostables put onto the market (around 120,000 tons) are actually effectively composted.

This is a remarkable piece of data because it shows that compostables fulfil their role – getting biowaste into treatment cleanly. As a result, the plants produce high quality compost outputs that sell on the market at prices UK composters dream of: €100 a ton and more. Above all, Italian users can be confident compost is beneficial. Today less than half of all UK AD and compost plants are PAS100/110 certified. Their outputs are classified as waste. This tells you a lot about what we are spreading to soil.

The amount of bioplastic used in Italy represents around 2% of the biowaste those materials collect and convey back to treatment. The proportion is clear – 1:50. Growth of food waste intercepted is matched hand-in-hand by the growth of bioplastics as collection tools.

Italy is ahead of all EU countries and the UK on food waste. But we are all going in that direction as post 2023 mandates come into force. What is the opportunity for us?

Questions for policymakers
The UK has the opportunity right now to realise this same potential as we go from small to mainstream food waste collections. The questions policymakers and the wider stakeholder community have to answer as food waste collections are rolled out are:

· Do we want to promote the incineration of plastic waste and the food stuck to it, as we are currently doing?

· Will we increase the transfers of financial resources from organic waste collection to incineration of the contaminants as now?

· Will the UK allow biowaste plants to be overcome by plastic as currently is happening?

· Will the UK allow biowaste plants to become terminals for what is essentially mixed waste as is currently happening?

· Will the UK permit the production of composts and digestate that contain so much plastics that farmers refuse to accept them, as is already happening?

If the UK is to answer ‘no’ to those questions, we must take the opportunity of ensuring that food waste collections are clean, can be treated, and produce quality outputs that have value for our soils. We need to establish a trajectory of quality – weekly separate collection – quality inputs, processes and outputs.

As Italy has shown, this requires simple legislation mandating collections with compostable packaging, a little enforcement to ensure councils do this, education to citizens to ensure compliance and an upgraded, modernised organics industry working together to handle new volumes and produce valuable products.

Appropriate deployment
In summary, when considered systemically and deployed appropriately, compostable products and packaging plays the role of:

1. A biolubricant for biowaste collections and treatment;

2. A reduction instrument, reducing plastic waste entering biowaste streams;

3. A plastic waste prevention instrument, substituting plastic where it does not fit;

4. A zero waste option, ensuring biowaste no longer goes to incineration but back to soil;

5. An instrument to drive the circular bioeconomy and protect our soils long term.

Research has found that farm plastics are a major pollution problem but not a priority for supermarkets. By David Burrows . There is more plastic in soils than in the sea, warned the Food and Agriculture Organization in 2021, but is anything being done about it? Not really, according to research published by the Environmental Investigation Agency (EIA). Agriplastics include protective greenhouse covers, plastic mulching, netting, pipes for irrigation and silage films. They increase short-term crop yields and extend local growing seasons, but can also reduce long-term productivity by deteriorating soil quality, EIA noted. They can also contaminate land, rivers, oceans and air. The campaigners quizzed 10 UK supermarkets – Aldi, Asda, Co-op, Iceland, Lidl, Marks and Spencer, Morrisons, Sainsbury’s, Tesco and Waitrose – about use of agriplastic within their supply chains and what they are doing to manage any pollution risks. All the supermarkets have engaged somewhat with suppliers on the issue – through trials, raising awareness or third-party certification standards – but only Lidl said it had sufficient information about the impact and risks of agriplastic pollution on the environment and human health. Measurable objectives, company-level sourcing policies and funding were also found to be lacking across all the chains. Indeed, seven supermarkets are currently working in some capacity with suppliers on the reduction and responsible management of agriplastics, with four supermarkets having more than one project underway in certain produce or product categories. However, none of the projects had any measurable or time-bound targets. In the UK, only 30% of non-packaging agri-plastics, such as polytunnels and bale wrap — excluding packaging such as chemical containers and sacks — is collected for reuse, according to APE (Agriculture Plastics Environment) UK, an industry-led initiative aiming to increase recycling of farm plastics. “[These supermarkets] have other sustainability targets, including plastic packaging reduction targets but little or nothing regarding the plastics being used by their suppliers to cultivate food and the devastating pollution that results,” said Lauren Weir, EIA senior ocean campaigner. "We need genuinely sustainable alternatives and for those with the purchasing power, such as our major grocery retailers, to take unified action across their international supply chains to ensure the UK’s food supply chain does not result in driving damage in other sourcing regions,” she added. The 10 supermarkets all said they’d welcome a sector-wide initiative dedicated to tackling agriplastic pollution. EIA called for “immediate and urgent action” on the most damaging agriplastics – microplastic applications and mulch films – and warned against simply switching to other materials (as many have done with consumer-facing packaging). Substitution is a “false solution”, the group said. The National Farmers’ Union has called for more research into bio-based alternatives to plastic that could be composted on farms. The Bio-based and Biodegradable Industries Association has argued that its members “make materials which are designed to resolve this pollution”. Some 12.5 million tonnes of plastic is used in agricultural production every year, FAO noted in its global report, the majority (93%) of it on land – which makes soil the likely destination for anything that’s damaged, degraded and discarded. How much, what happens to it all and the impact it has are poorly understood, according to the Environment Agency’s 2019 ‘The state of the environment: soil’ report . There are also increasing concerns about the levels of plastic spread to land in digestate and sewage sludge . Other than an unsupported agriplastic burying and burning ban, the UK government has little or no policy ideas or plans to address the issues, despite having the regulatory responsibility to do so, said EIA. Others have been trying to raise awareness for years. “Healthy soils are vital to sustaining food supplies, act as a critical flood defence and store three times more carbon than the atmosphere, yet the UK does nothing as study after study reveals that plastic contamination of soil is even worse than it is in the sea,” Ellen Fay, director of the Sustainable Soils Alliance (SSA), told Ends Report following the FAO report . EIA is calling for mandatory reporting on agricultural plastic products and an extended producer responsibility scheme for the materials. Further research into alternatives and their benefits and trade-offs is needed, as well as support for agroecology and permaculture in UK farms to help reduce agriplastic use. The new research comes in the midst of fruit and vegetable shortages. The trouble is that agricultural plastic helps grow more food in a hungry world, APE UK chief executive Ian Creasey told the FT . “Plastics play a really important part in farm life and have environmental benefits,” he said. “That works if you efficiently collect the plastic on the farm. It doesn’t work if there isn’t that ‘circularity’ and you let that plastic get burnt or go to landfill.” April 11, 2023 Read the original article here on Footprint, Sustainable Responsible Business

Environment Secretary Thérèse Coffey is set to confirm a ban on the supply of a range of harmful plastics later this week. The ban will include single use plastic plates, trays, bowls, cutlery, balloon sticks, and certain types of polystyrene cups and food containers. This comes after the Government’s consultation on plans to ban these single-use plastics, which received overwhelming public support. To allow businesses time to prepare, the bans will be introduced in England from October 2023. Environment Secretary Thérèse Coffey said: “A plastic fork can take 200 years to decompose, that is two centuries in landfill or polluting our oceans. “I am determined to drive forward action to tackle this issue head on. We’ve already taken major steps in recent years – but we know there is more to do, and we have again listened to the public’s calls. “This new ban will have a huge impact to stop the pollution of billions of pieces of plastic and help to protect the natural environment for future generations.” England uses 608 million single-use plates and 2.3 billion items of single-use cutlery — most of which are plastic — per year, but only 10% are recycled. Plastic cutlery was also in the top 15 most littered items by count in 2020*. These plans build on efforts to eliminate avoidable plastic waste, including one of the world’s toughest bans on microbeads in rinse-off personal care products announced in 2018, restrictions on the supply of single-use plastic straws, drink stirrers and cotton buds in 2020, and our Plastic Packaging Tax in April 2022. We have also taken action at an international level and have led the way in pushing for an ambitious and effective treaty to end plastic pollution, including through a coalition of over 50 countries. Through the Environment Act, the Government is bringing in a wide range of further measures to tackle plastic pollution and litter, including: Introducing a Deposit Return Scheme for drinks containers to recycle billions more plastic bottles and stop them being landfilled, incinerated, or littered. Through a small deposit placed on drinks products, the DRS will incentivise people to recycle; Our Extended Producer Responsibility scheme will mean packaging producers will be expected to cover the cost of recycling and disposing of their packaging. Our plans for Consistent Recycling Collections for every household and business in England will ensure more plastic is recycled. * According to Defra’s 2020 Litter Composition Report

Kevin Clarke got the opportunity to pitch our riji trays to investors at Venturefest South. An exciting day full of people with new ideas deserving of winning some capital. 'A compostable alternative to the single-use trays in convenience meals and takeaways, which are use two billion times a year in the UK, developed by KCC Packaging in Eastleigh. Managing Director Kevin Clarke said: "Everybody knows the current takeaway-type products which are used, which are largely polypropylene, a microwavable product and a plastic which is not widely recycled." He said KCC Packaging's products are suitable for fresh or frozen foods and safe at up to 240 degrees Celsius in the oven. They are made from plants and have a low carbon footprint, he said, and the range includes trays, lids for takeaways and cups.' Article below:

Responding to this week’s UCL study into the use of home compostable packaging in the UK, Chairman of the Bio-based and Biodegradable Industries Association, Andy Sweetman, said: “The results of this welcome research show that compostable packaging actually does biodegrade but that there is huge variability when the process is handled through home composting, and confusion over which materials are suitable. Many home composters are actually trying to compost plastics which are not at all compostable. We need to end the use of terms like degradable and biodegradable to avoid consumer confusion." “In order to treat food and garden waste most effectively on a large scale, we need household collection systems and industrial composting. Consumers should be encouraged to place certified compostable packaging into their food waste bins as in many countries around the world." “Home composting is a part of the picture and we encourage this practice, while large scale composting achieved through an industrial process, involving both a composting phase and anaerobic digestion to produce soil-improvers and biogas will give all householders a route to recycling food and garden waste along with certified compostables".

The REA (The Association for Renewable Energy and Clean Technology) have published a compost site map. This is collated from published data and is separate from the work REAL are doing on sites accepting compostables. The map shows permitted compost sites, those who are ABP approved (so can take food waste) and those who are Compost Certification Scheme (PAS100) certified. Find the map HERE.

Sustainable packaging challenges for the county and beyond  On Thursday 15 September 2022, the University hosted Growing Kent and Medway’s first Sustainable Packaging Forum, bringing together key stakeholders from industry, policy and academia for an afternoon of inspiring presentations and the opportunity to discuss how to deliver a real circular sustainable packaging ecosystem across Kent and beyond. Attendees enjoyed a series of inspiring talks from leading industry on the current sustainable packaging goals and challenges facing the food and drink sector, as well as getting the chance to join a regional business network to address packaging challenges and targets from the roots up. Opening remarks were given by Dr Lori Fisher, Growing Kent & Medway research fellow, who introduced the forum’s aims and reflected on the current challenges in packaging, and opportunities to collaborate. The first speaker, Dan Crooks from iFruit, introduced the packaging challenges from a suppliers perspective. Dan was followed by Dr Jon Mitchell from Nextloopp who introduced the audience to their circular food-grade PP from post-consumer packaging. The audience then heard from Kevin Clarke from KCC Packaging who presented how compostables can make food waste work in a circular environment. Graham Hayward, from Kent based paper mill Smurfit Kappa, then showcased the sustainability capabilities of the mill. The final speaker, Kieran Bevan from Triflex productions took the audience through sustainable flexible packaging and solutions for food and drink businesses. Dr Rob Barker, Senior Lecturer at Kent and co-host of the event said: “It’s clear that we have the technologies emerging across the sector to move away from a packaging ecosystem reliant on virgin and traditional packaging materials, but much work is still needed to optimise and close the loop on these systems and allow us to move quickly enough to embrace new technologies. “This will only be possible through the continued, open conversations that the Forum started and we’re excited at the University of Kent and as the Growing Kent and Medway consortia to take a lead in facilitating these conversations and enabling collaborations between our academic community and industry to make this vision of a circular sustainable packaging ecosystem a reality.” Networking was held before and after the forum, so that delegates were able to network with other like-minded attendees and discuss their ideas with the guest speakers. This provided a unique opportunity for attendees to meet technical experts to discuss packaging needs and challenges, and information regional decision making. Audience members were able to ask questions to the speakers and receive feedback on their packaging needs and ideas. Kevin Clarke at KCC Packaging said: “The event enabled a robust discussion on the challenges of allowing the status quo to persist. Much stronger actions are needed to create meaningful systemic changes in packaging & food waste management, if the UK is to gain better outcomes for the environment in our drive to reach net zero. This need for action was underlined by the broad section of industry experts who supported the event.” The team at Kent will be issuing a report on the future of sustainable packaging in the coming months.

The Bio-based and Biodegradable Industries Association (BBIA) has written to the Department for Environment, Food, and Rural Affairs (Defra) challenging the stance it has currently adopted with compostable packaging. Despite growth in demand for ‘organic recycling through composting and anaerobic digestion’, the Government’s response to the consultation on Extended Producer Responsibility (EPR) shows a disregard for compostables. The letter also claims that, ahead of an official response on the Consistency consultation, Minister Jo Churchill ‘stated to a fellow stakeholder that “we do not want compostable bags”’. By determining compostable bags to be unsuitable for food waste collections in England, the letter says, Defra is seemingly stating that ‘we some small doubts about compostable films, despite clear evidence in their favour, we prefer not to have them. Instead, we’ll have plastic bags, which we have no doubt will leave macro and microplastics in compost, digestate, and, therefore, soils.’ In recent months, BBIA said, Defra has developed a ‘decidedly polemic view ​​regarding compostables and globally accepted standards for biodegradability’. Continuing, the association asserted that ‘rather than engage in meaningful scientific discussion’, the Department has ‘opted to move forward with a system for packaging and food waste which goes against the actual evidence, net-zero ambitions and desire of the market.’ In the letter, BBIA says it has been in ‘regular contact’ with Defra officials, seeking meetings with Minister Jo Churchill and offering her a visit to ‘the UK’s largest composting facility, which actively seeks more compostable packaging.’ However, the association claims that the apparent lack of engagement is ‘undemocratic’. The letter concludes by inviting the Minister and the Department’s Chief Scientific Advisor to meet with the BBIA to discuss the risks posed by the current policy stance, including: The contribution of compostable products (bags, packaging and other items such as teabags) to the future bioresources (waste) industry and UK PLC in the context of net-zero. The underlying science and standards relating to biodegradation of (compostable plastic) materials and the false assumptions relating to microplastics. The letter is accompanied by others from stakeholders in the compostables industry. In one of these, organics reprocessors ENVAR, questions the evidence behind the decision to label compostable packaging as ‘do not recycle’. This, ENVAR asserts, will damage producers of compostable packaging and ‘raise doubts’ among the company’s compost customers. Keenan Recycling also issued a letter to Defra on compostable packaging’s exclusion from recycling labels, stating that the Department’s position that compost may contain microplastics ‘could really set the industry back’, damaging the trust the company has built with farmers and agricultural groups. The letter called on Defra to explain its grounds for this claim, adding that ‘if there is an absence of such evidence’, it would ‘appreciate the ability to continue to collect and process compostable packaging along with food waste’.

Pollution from plastics is a global emergency in need of a robust UN treaty, according to a report. The Environmental Investigation Agency (EIA) says there's a cascade of evidence of harm from plastics. It argues that the plastic pollution threat is almost equivalent to climate change. The air we breathe now contains plastic micro particles, there’s plastic in Arctic snow , plastic in soils and plastic in our food. It's reported, for instance, that about 20 elephants in Thailand have died after eating plastic waste from a rubbish dump. The authors urge nations to agree a UN treaty with binding targets for reducing both plastic production and waste. "There is a deadly ticking clock counting swiftly down," said the EIA’s Tom Gammage. "If this tidal wave of pollution continues unchecked, the anticipated plastics in the seas by 2040 could exceed the collective weight of all fish in the ocean." The United Nations has identified three existential environmental threats - climate change, biodiversity loss and pollution - and concluded that they must be addressed together. Multilateral agreements on biodiversity loss and climate have existed for nearly 30 years (although they have failed to halt CO2 emissions or protect the natural world). The idea of a dedicated plastics treaty has been opposed by some nations in recent years. But more than 100 countries, including the UK, are said to favour a treaty being proposed at the next UN Environment Assembly in February and March. Sources say outright opposition is weakening, although there's a dispute as to how strict the treaty should be, and whether it should be legally binding or voluntary. US President Joe Biden has announced that the US now supports a global agreement, previously resisted by former President Donald Trump. It’s not clear, though, whether he can win approval from Congress, as most plastics are made from oil and gas - and they're both produced in the US.

Dear readers,  Happy New Year to all our readers and our best wishes for a healthy and prosperous year ahead. Despite most of us taking a long vacation, it seems the newsreel never ceases and there are lots of reports and updates to give in this edition. We enter the year awaiting the outcome of the consultations DEFRA have promised to publish on waste collections, EPR and DRS. Over three years have passed since the first consultations were launched, and I believe I speak for many of those in the associations by saying that we want to make progress as fast as possible and implement the policies. It is time to act. We have submitted as further evidence to DEFRA a recent scientific paper from Spain showing analyses from five composting plants in which absolutely no residues of compostables were found in compost whereas considerable residues of plastics are to be found. The study proves that: "No debris from compostable bioplastics were found in any of the samples, meaning that if correctly composted their current use does not contribute to the spreading of anthropogenic pollution. "Our results suggested that the use of compostable polymers and the implementation of door-to-door collection systems could reduce the concentration of plastic impurities in compost from OFMSW." It is always good when scientists confirm that these materials do what they claim to do- they compost. This is particularly relevant now that reports of the damage done to our health from microplastics are confirmed by scientific studies, as the Daily Mail reported here . DEFRA is not alone in consulting. Northern Ireland’s consultation on Single-Use Plastics has been extended until 14 January so please do submit your thoughts – the link is here . HMRC has consulted on the Plastic Tax, which all BBIA members are still horrified and enraged by – not because we don’t want to pay taxes, but because our category will be probably the one most taxed, as we cannot chemically, biologically or physically recycle composted plastics back into compostable plastic. We submitted a long paper on the methodology of accounting for the tax and hope HMRC will read it, at the very least. I suppose it is too much to ask for justice. Enjoy the newsletter and looking forward to seeing you, Covid allowing (will it ever end?). David Newman Managing Director
