  • Unavoidable food waste- things that were never edible .ie. Bones, potato peelings from chip production
    Avoidable food waste- things that were once edible such as a bread that’s gone mouldy and food scrapings from plates.

    • 2. General Waste
    • 3. General Waste •The Green Fence effect came in to effect at the beginning of 2013. This has filtered down the supply chain to us which means we cannot send our poorly segregated plastic to China. This has led to much of the plastic being mixed with General Waste and sent to incineration rather than being recycled. •While investigations are being made into the plastic recycling issues, we need to investigate other means to reduce our overall general waste. 11/19/13 Version: [###] Classification: Internal Owner: [Insert name] 3

This was while one container a month was being sent for incineration. •This cost £12,800 a year. •The average cost per tonne (including container rental and transport) between July 2012 and July 2013 comes to £186 11/19/13 Version: [###] Classification: Internal Owner: [Insert name] 4

    • 6. General Waste •In February 2013,after a week long visit at Ricoh, a report was produced by Waste and Resources Action Programme (WRAP). This report summarised the results regarding waste in the kitchen/catering areas at Ricoh. •Table 1 shows the total kitchen waste per year split into categories of avoidable food waste and unavoidable food waste. From these results it is estimated that 4.6% of the Total General Waste volume on RPL site is accountable as food waste from the Canteen facilities. 11/19/13 Version: [###] Classification: Internal Owner: [Insert name] 6
    • 7. Anaerobic Digestion 19/11/13 Version: [###] Classification: Internal Owner: [Insert name] 7
    • 8. Anaerobic Digestion • Anaerobic digestion is widely regarded as the most sustainable method of disposal of biodegradable waste. • 100% of the waste is utilised. Gases are used to generate energy and residue is used as fertiliser on fields. • Through doing this it is possible to create a carbon footprint saving of 0.5 to 1.0 tonne of CO2 equivalent per tonne of food waste. 11/19/13 Version: [###] Classification: Internal Owner: [Insert name] 8

    • 10. Anaerobic Digestion This table shows the constituents of Food waste in which are accepted by Cartwrights and “Harper Adams Energy”. These products are the main constituents of our general waste and are permitted by Harper Adams. These products are not permitted in any of the waste sent off to Anaerobic Digestion. As a relatively small facility we do not handle these anyway. 11/19/13 This specifies no copy, laminated or printer paper. However, paper towels and biodegradable tissue papers are permitted.

    • 11. The Benefits 1. Cost • We are currently paying £138.50 per tonne of waste sent for incineration with Heat Recovery. When including the transport and container hire this amounts to £186 per tonne. • Costs for Anaerobic digestion are lower at £50 +VAT per tonne. This is including transport and 240ltr wheelie bin hire. 11/19/13 Version: [###] Classification: Internal Owner: [Insert name] 11
    • 12. The Benefits Cost Breakdown Incineration Process cost Anaerobic Digestion £138.50 per tonne £12 per 240 ltr bin Container hire £1.50 per day Included in process cost Transport/ pickups Weekly pickup included in process cost £216.27 twice monthly Total cost per £186* tonne 11/19/13 £50 Version: [###] Classification: Internal Owner: [Insert name] 12 * One container hold 5.5 tonnes
    • 13. The Benefits 2. Key Fundamentals 4 & 5 (Environment and CSR) • Possible net savings of 960kg CO2 equivalent per tonne of food waste. (4281.6kg per year) • Carbon Dioxide and methane products are prevented from entering the environment therefore cannot contribute to Global Warming. • Leftover residue is used on local fields to promote growth and production. • Electricity and Heat products are put back on the grid to fuel local homes and businesses. • This is a closed loop system as 100% of the Waste is recycled into useable products. 11/19/13 Version: [###] Classification: Internal Owner: [Insert name] 13
    • 14. The Logistics • After an initial one-off delivery charge of £20 for the clearly marked 240 ltr “Food Waste” bin it is collected once a week and the bin hire is included in the cost. • Each collection is provided with a duty of care waste transfer note, weighed and recorded for our documentation. • If contamination occurs other than tissue paper and paper towels then the bin will be returned to us. This means segregation rules have to be created and managed and waste streams mapped and managed by the Recycling centre. 11/19/13 Version: [###] Classification: Internal Owner: [Insert name] 14
    • 15. In Conclusion Although segregating Food Waste will not solve the problem of ever increasing volume of General Waste due to plastics, it will alleviate some pressure and improve the situation. Costs of Anaerobic Digestion are much lower than Incineration and the environmental impact is considerably lessened. If we decide to switch to Anaerobic Digestion we can make a total yearly saving of around £590. In addition to this we could make a net saving of 4281.6kg CO2 equivalent. This is an important step in demonstrating the Ricoh Way (KF4). This process has been benchmarked through the BESST group and has been proven to work in other organisations such as Lyreco. 11/19/13 Version: [###] Classification: Internal Owner: [Insert name] 15
