A comparative assessment of the energy and carbon balance of utilizing straw

摘要: Abstract There has been a recent growth of interest in the potential for using straw as an energy source to generate electricity and/or heat. The balance this process is important measure sustainability such activity, while CO 2 emitted and that saved by offsetting need produce other means are also important, given U.K.'s obligations reduce emissions. An existing methodology adopted calculate estimates primary inputs outputs. Results calculations presented considered context their implications uses represented four scenarios. One scenario use fuel commercial scale power only, heat only combined (CHP) plants. Overall, CHP production provides most favourable balances. compared with those alternative or disposal methods straw, scenarios, producing conventional means. Conclusions drawn concerning contributions carbon balances recommendations made further work.
