Industrial processes are tightly connected with emission of enormous amount of waste gases, waste waters, and solid waste. These are either by-products or end-products of the plant operational cycle or the combustion process itself. The carbon intensive economy relies on fossil fuels and is emitter of green house gases, toxic gases, waste waters rich of organic and inorganic substances, as well as fly and bottom ash. Waste possess a threat to the environment and to human health, as it is toxic yet abundant.
New frontiers and challenges are introduced in front of proven biochemical processes, such as photosynthesis and photorespiration, and going hand in hand with molecular biology, plant cells engineering, mapping genetic identity and enhancing the cell metabolism, greenhouse and toxic gases are metabolized further into energy.
