Composite material

 Biomass briquettes are a biofuel substitute to coal and charcoal mostly made of green waste. Briquettes are mostly used in the developing world, where cooking fuels are not as easily available 

Synthetic fuel or synfuel is a liquid fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid biomass.  Examples are fuel oil, diesel oil, gasoline, and methanol, clean solid fuels, and low-calorific value, medium-calorific value, and high-calorific value gas. 

 Fly ash is the fine ash produced that develops cementitious properties when mixed with cement and water. Fly ash in concrete is widely used to the strength of concrete. 

 Waste-to-Energy is a technologically advanced means of waste disposal that is widely recognized for reducing greenhouse gases—particularly methane—by eliminating emissions from landfills. Scientists have identified landfills as super emitters of methane, a greenhouse gas that is 84 times more potent as a climate-warming gas than CO₂. 

Sustainable solution to the global sand shortage and coastline regeneration

 Composite lumber is a material that is a mixture of wood fiber, plastic, and some type of binding agent. These ingredients are put together to form a material that is denser, stronger, and heavier than wood alone. Reducing need for deforestation
