very local bio-waste management services
most are not ‘waste – orientated’ have a need for compost mostly garden wastefood wastenot much “humanure”
Previous Projects:Previous Projects:
Grundtvig: Growing with CompostEuropean 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 NeighbourhoodsUK 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.

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: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 practiceDisseminate via training; events; web;
blogs; video

Aims and Goals of the Project 1:Aims and Goals of the Project 1:
1.Identifying and describing suitable systems within a range specified by the CCN (members of the AD steering Group):
• Between 0.5m3 and 10m3 • 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:Aims and Goals of the Project 2:
2. Components and Operation Manual for a system:
• Size 1m3 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
