Turning garbage into revenue

Energy as a waste product

Müll_Geld_Kran_teaser

Garbage that is burned and converted into power, district heat, and ash releases significantly fewer climate-damaging gases than garbage deposited in landfills. However, the practice of thermal recycling (which converts waste into energy) is also booming because, all over the world, there is an increasing amount of garbage and less landfill space. Across the globe, approximately 230 waste-to-energy plants will soon be added to the 2,200 or so that are currently in operation. The aim is to achieve greater efficiency, lower costs, and reduced CO² emissions through metal recycling, ash treatment, and waste heat recovery. Continuous measuring technology helps to determine efficiency reserves. Continue reading

Using CO2 “green” products

Cutting emissions: there is another way

The energy revolution has also brought to light the fact that carbon dioxide is only a bad thing when it is released into the air. If, however, CO2 is captured and stored, it could make a significant contribution to reducing CO2 and generating “green” products. Carbon dioxide is the key ingredient in the power-to-gas concept, for example. This technology involves storing renewable energy in the form of synthetic methane gas to provide a combined solution that both reduces CO2 and allows problematic green power surpluses to be stored. What’s more, CO2 forms part of the process for producing plastics which are free of petroleum. Continue reading
