Benefits of organics recycling
@REAssociation
• Better environmental option to treat waste• Source of renewable heat, power and gas • Produces valuable products (soil improvers and
biofertilisers)• Increase crop yields• Compost increases soil organic matter and improves soil
structure
• Liners and re-used carrier & fruit & veg bags• Reduced yuk factor • Less contamination inside the liners/bags• Cost savings when biodegrading them rather
than removing non-compostables
Benefits
Opportunities
• Reduce contamination• Resources and Waste Strategy• Plastic packaging tax?• Extended Producer Responsibility
1. Recognising them• Clear labelling so they are easy to identify• Working towards a more consistent ‘look’ for
compostable bags/liners to make identification easy!
2. Collections3. Processing capacity
• Sites approved to treat food waste (APHA July 2020)• 112 AD plants• 48 compost sites
• Open-windrow site that could compost cups, lids etc where they’ve only been in contact with milk or cream (approx300 sites)
4. Performance• Acceptable standards• Experience and trials@REAssociation
Getting it right
• Clear labelling so they are easy to identify• Various different certification marks
• Working towards a more consistent ‘look’ for compostable bags/liners to make identification easy!• Education and guidance so people know
what to do with compostables• WRAP guidance• Which Bin? Information and stickers• Funding for local authorities communications
@REAssociation
Recognising them
Collections
@REAssociation
Collections• Usually along with food waste• Examples of success
• Olympics in 2012• Vegware’s closed loop• Keenan’s commercial food waste
Processing
@REAssociation
Treatment capacity • Sites approved to treat food waste (APHA July
2020)• 112 AD plants• 48 compost sites
• Open-windrow site that could compost cups, lids etc where they’ve only been in contact with milk or cream (approx 300 sites)
Performance
@REAssociation
• Need to ensure that compostable materials perform as they should
• Acceptable standards - EN 13432 or EN14995 • Disintegration – at least 90 % w/w < 2 mm within 12 weeks• Biodegradation – 90% within 6 months• Ecotoxicity – plant growth and potentially toxic elements limits• No negative effects on compost• Independently certified
• Experiences and trials
@REAssociation
Thank you!
