Carbon credits

Organic waste can be converted into Biochar generating carbon credits.

How can we make Surrey an even better place to live?

SCC is building an eco-park with a gasification plant for residul waste. Organic waste is either composted or digested, while wood is sent overseas.

If all organic waste was processed seperately using the gasification plant the result would be "biochar" and energy. The biochar is a form of soil conditioner and also carbon sequestion technique. When buried in topsoil the carbon is sequested for a period between hundreds and thousands of years.

Besides generating carbon credits that can be sold to bolster SCC budgets, the biochar also acts as a means of locking in nutients into the soil. This reduces the need for fertilisers and prevents fertiliser run off into rivers and steams with the associated negitive impacts on river ecology. Studies in carbon enriched soils indicates that besides reducing the need for industrial fertilisers, most plants grow faster with greater abundance and vigor.

Besides producing better produce at lower cost, surrey farmers that choose biochar to enrich their fields could also label their produce as carbon negitive. This would give them an additonal marketing tool in the organic/environmentally aware arena.

So it helps Surrey be a better place by: Reducing waste; becoming a carbon negitive council, helps the environment, supports agricultural business, generates funds to support the residents of surrey, requires no or minimal further investment, is self supporting in terms of energy usage (in line with the plan for residual waster processing).
