Why Treat Food Residues On-site?Why Treat Food Residues On-site?

KINGSWAY COURT,

GLASGOW

6 Blocks contain 684 flats

Transient population thus 600 assumed to be occupied

On-Site Food Residue Collection has c200 participants

Participants average 3kg Food Residues per week (0.16t/a), TOTAL 31.2t/a composted on-site

Remaining 400 residents use waste chutes – ultimately landfill, TOTAL62.4t/a to landfill

Methods of Roll out• Engagement, door-knocking, awareness (SWAG survey)

• Caddies & Liners

• Bins in Chute Rooms to Door-Door Collection

• Twice weekly collection; Continuous Engagement

• Licence Facility and Install IVCs

• Open Days, Primary School days, Newsletters, Raised beds

• SWAG Mid-project survey and Love Food Hate Waste Leafleting

BEHAVIOUR CHANGE

Participation currently static but can be increased

Quantities (kg/wk/participant) beginning to fall back

SWAG survey shows:

• 86% see no need for improvements to 86% see no need for improvements to collection servicecollection service

• 30% have started to change purchasing 30% have started to change purchasing habitshabits (buying less,using only what’s needed, reduced portions (Somerset)

Thus per flat per annum:

Participants in On-Site Composting generate 5kgCO5kgCO2eq2eq/flat/flat

Non-Participants generate 57kg/CO57kg/CO2eq2eq flat flat

The total annual emissions for Participants = 0.936tCO0.936tCO2eq2eq

The total annual emissions for non-participants = 22.78tCO22.78tCO2eq2eq

On-site composting generates 30kgCO2eq/t composted

Landfill generates 365kgCO2eq/t disposed(DEFRA/DECC Guidelines for GHG Reporting, 2009)

Potential GHG Reductions at KINGSWAY

At the average rate of waste arisings:

If all went to landfill as hitherto, then 93.6t/a would generate 34.16t CO34.16t CO2eq2eq

If all were to be collected separately and composted on-site only 2.8tCO2.8tCO2eq2eq would be generated

The CO2eq emission saving is 31.6t31.6t

A reduction of 92% 92%

Replicated across Glasgow, or Scotland, the potential is exceptionally exciting!

From KINGSWAY COURT to SCOTLAND

• Create a community garden on the Kingsway Court High Rise Estate,

• Environmental education/awareness-raising with local primary schools,

• Redevelop the Glasgow Greenies youth environmental awareness and action programme,

• Promote recycling more broadly (dry recyclables),

• Promote lower household energy use and reduced carbon footprints,

• Encourage behavioural change,

• Develop volunteer involvement in and local resident management of these programmes.•Anniesland College and Outreach Training

CCF PROJECTS LINKED to FOOD RESIDUES

Problems:Problems:

• transient & problematic population; unemployment up

• only 65% of members (c30% occupants) participating weekly

• fire regulations necessary because of arson and vandalism

• in recent survey 58% still didn’t know what happens to collection

• initial operational teething resulted in odour – largely resolved but inside maturation still not ideal

• Waste Management Licence costs work inflate costs, but may soon be resolved

Conclusions:Conclusions:• 96% of participants rate system Good to Very Good

• 48% of participants much more aware of food wastage

•99% used caddies and liners and found them handy and hygienic

• average 2.65kg (5.9lt) per flat per week (WRAP 0.5kg)

•The current collection system costs >£300/t, but costs would be incurred by segregated collection for any other disposal

• considerable GHG reductions achievable (will be better w/o tspt)

• >30% participants recorded behavioural changes, 2 want to be Food Waste Champions

• could achieve ZERO WASTEZERO WASTE for food and facilitate other recycling

• the project model is valid for roll-out to other localities

Recommendations:Recommendations:

•continual engagement and awareness raising required

• new survey required in May

•engage more volunteers and part-timers from Kingsway unemployed

• set up SLA with GCC for ALL ALL deliverables

•System can be perfected and rolled out elsewhere (already 2 other Housing Associations interested)

• implement symbiotic CCF projects to maximise benefits – Behavioural Change and GHG reductions
