Sample Carbon Savings from a Tri-generation Biomass Waste2Energy Centre

The findings of a recently published study by Siemens and Professor Horst Wildemann of the Technical University of Munich has identified that global power demand is set to increase on average by nearly 3 percent per year over the current and next decade. Cumulatively, this moderate growth would cause overall power demand to rise by more than half of its current level between now and 2030. If new power plants are added as foreseeable, associated CO2 emissions are likely to increase by a quarter or 3,500 megatons.

We transport a large volume of materials from a large variety of sources such as homes, industry, retailers, and the leisure and service industries to large waste management sites. Businesses who pay large tariffs to dispose of large volumes of wood, cardboard, paper and food wastes by converting these instead into source of energy to run their business around the world would play their part in assisting carbon reduction programmes, and reduce their need to draw on fossil fuel based energy production.

Below is a sample of the Carbon savings that 1 tri-generation energy centre could provide from a standard footprint supermarket.
