3 problems > 3 driving challenges. 1 > Greenhouse Gases. 2 > Increasing Energy Demand. 3 > Waste Management. Cleantech is called to solve these challenges, using Biomass, Agricultural, Domestic & Industrial Residues as alternative fuels for Power and Thermal Applications. Despite efforts to increase the recycling of MSW, a non-recyclable fraction is still disposed of in landfills. This fraction contributes to greenhouse gas emissions. However, this non-recyclable fraction does have a potential use as Refuse Derived Fuel or Solid Recovered Fuel (RDF/SRF): heat and electricity clean generation.
