Turning Plastics into Liquid Fuel

Turning Plastics into Liquid Fuel

The widespread use of large volumes of plastics has created serious environmental issues. Polyethylene and polypropylene make up more than 60% of the total plastic content of municipal solid waste. These plastics originate primarily from fossil fuels.
Scientists in the United States and China have now developed a method of efficiently turning these plastics back into useful fuels and chemical feedstocks.  Read more »

Concentrated Solar Heat in Developing Countries

Concentrated Solar Heat in Developing Countries

The largest energy demand in many communities is for producing heat, for example for cooking or water sterilization. Using electricity, if available, risks regular blackouts and high costs and wood contributes to deforestation and indoor air pollution.
Using concentrated solar power directly, without the need for expensive and complex components, is ideal for many developing communities energy needs.  Read more »
