Description

Presentation by Cath Kibbler of the British Community Composting Network held at the biogas information seminar in Wageningen the Netherlands, 4 October 2009, organized by the Wageningen Environmental Platform & the Community Composting Network

What is the Community Composting Network? 218 Members in England, Wales and Scotland Full, Associate and individual members Full members – not for profit organisations very local bio-waste management services most are not ‘waste – orientated’ have a need for compost mostly garden waste food waste not much “humanure”

 

 

 

 

Previous Projects: Grundtvig: Growing with Compost European education based project. Working with FoE Slovak Rep., Czech University of Agriculture, Ecological Recycling Soc. & IASON (vocational trainers), & REEUSE. To create, demonstration sites, website, toolkits, training materials & events. SPAN : Sustainable Production Across Neighbourhoods UK sustainable development project. Working with Federation of City Farms, HDRA, Permaculture Association. To give assistance to communities who want locally produced food by providing experts, information tools & events for sharing and disseminating information & best practice.

Food Waste in the UK On the Farm : ? Processing: 4.6m tonnes of food waste in the UK (13% of total output) Supermarkets & Retailers: 1.6 million tonnes Households: 6.7 million tonnes 12.9 million tonnes of food waste and wasted food in the UK

Redistribution of unwanted Food

Phases of the CCN project: 1. Identify & Define suitable systems 2. Create a guide for assembly & operation Test build at least one demonstration plant 3. Install pilot plants in a number of TSO Project sites and provide training & support Throughout: Document experiences and best practice Disseminate via training; events; web; blogs; video

Micro AD in Context 5. Local centralised food waste processing Wyecycle

Aims and Goals of the Project 1: Identifying and describing suitable systems within a range specified by the CCN (members of the AD steering Group): Between 0.5m 3 and 10m 3 To process between 5-100 tonnes material annually Food waste a priority but also sewage; sewage sludge; animal manure; and pet manure (cat and dog) Not so much garden waste Produce a sanitised NPK fertiliser for horticulture Must be gas – safe Must meet UK regulations

Identifying and describing suitable systems within a range specified by the CCN (members of the AD steering Group):

Between 0.5m 3 and 10m 3

To process between 5-100 tonnes material annually

Food waste a priority but also sewage; sewage sludge; animal manure; and pet manure (cat and dog)

Not so much garden waste

Produce a sanitised NPK fertiliser for horticulture

Must be gas – safe

Must meet UK regulations

Aims and Goals of the Project 2: 2. Components and Operation Manual for a system: Size 1m 3 of a digester tank volume Substrate primarily foodwaste, solids content 5% solids (dry matter), slurry type digester Particle size reduction via a waste grinder/chopper/mill or macerator Suitable mixing & buffer tank for mixed substrates ABPR compliance to include a simple pasteurization unit and HACCP procedure; monitoring and testing equipment & proceedure Biogas storage and piping floating dome or similar compliant with relevant gas regulations
