Waste is a large problem in all parts of the world and landfilling is no longer viable. Waste-to-Energy is the only viable large scale solution.
Energy prices are increasing and over a 10+ year period they are forecasted to increase further. Alternatives to fossil fuels will likely become even more attractive.
Countries exporting fossil fuel would likely like to export more and make use of alternative available energy sources such as waste or biomass. The same can be said for the countries importing the fossil fuel.
Renewable energy is still, despite its massive growth over the last decade and the impacts of the financial crisis in Europe and the US, the most dynamic investment field for both yield and value investors.
