Energy from waste? Killing two birds with one stone Panacea to Energy crisis and waste treatment Have you imagined that electrical appliances would be useless in one day? Have you ever thought of living in total darkness? Concerns over energy crisis are alarmingly growing. Fossil fuels are estimated to deplete within 100 years at current consumption rate1. Being a member of global village, every cities and countries in the globe are responsible to pay joint effort to remedy the situation. Intergovernmental Panel on Climate Change (IPCC) released the fifth assessment report on 13 April, urging policymakers to put a halt to the use of non-renewable energy sources at once2. â€Å"The high speed mitigation train needs to leave the station very†¦show more content†¦Chemical conversion has two methods to generate electrical energy, i.e. direct and indirect. The direct method is the combustion of MSW6. Since every matter stores energy, a direct burning of MSW generates heat, which in turn provides energy to drive the motors for electricity production6. The indirect method is pyrolysis, followed by gasification7. Pyrolysis is a term describing the segregation of substance after thermal cracking and condensation8; gasification is a process of converting carbon-containing compound into energy-rich fuels under specific condition8. To illustrate these two concepts, you can think of the process of turning paddy to grain, and then to a bowl of rice. To separate grain from paddy, we need tools like paddy separator and husker aspirator. By breaking paddy into smaller pieces, followed by segregation, we can obtain grains, which can be further processed to useful materials, and husks. This procedure echoes with pyrolysis, a process that uses machineries to separate useful and non-useful materials after breaking down the input substances to other materials. At this stage, what we have obtained is grain. To convert it to rice that can be consumed by human, we have to polish it and cook it. This action describes gasification, which turns carbon-containing compounds (grains) to energy-rich fuel (cooked rice) underShow MoreRelatedOne Significant Change That Has Occurred in the World Between 1900 and 2005.
