Go Green!


This week, I'm going to talk about environment in Singapore. Then I was thinking in Thailand, we have waste problem so I think in Singapore have the same waste problem as Thailand. So, I am going to focus on urban waste. Nowadays waste issue is one of the cause of global warming,so today Singapore is trying to management waste problem. Professor Jim Swithenbank has experience about waste management over 80 participants from the industries and public agencies. Prof Swithenbank’s presentation affirmed the importance of integrating the waste management process in climate mitigation efforts. So the way to low-carbon environment is the active recovery of materials and energy to reduce the environmental burden from high consumption patterns. There are called the 3Rs: Reduce, Reuse and Recycle, is necessary to conserve resources and reduce the amount of waste going to the landfill. Waste being largely carbon neutral, has similar calorific value as raw material, and could serve as feedstock to power the energy cities need. Next, energy recovery is the next step and could be achieved through combined heat and power (CHP)system,cogeneration in short, or even tri-generation system which recovers waste heat for cooling. This is reflect on Singapore’s situation. Singapore’s energy-intensive industries and power generators look to be in the best position to exploit both cogeneration and tri-generation capabilities.

In my opinion, I think these 3Rs is good process to help management waste problem. In Thailand we also use 3Rs to recover waste then make waste to energy. I think manage the waste, it is a way to help to decrease the global warning. Go green!
