Waste-to-Energy

Waste-to-energy (WtE) or energy-from-waste (EfW) is the process of creating energy in the form of electricity or heat from the incineration of waste source. WtE is a form of energy recovery.

Ways to keep freshwater clean through waterway transportation:

Bioethanol- an alcohol made by fermenting the sugar components of plant materials and it is made mostly from sugar and starch crops. Ethanol can be used as a fuel for vehicles in its pure form, but it is usually used as a gasoline additive to increase octane and improve vehicle emissions.

Biodiesel- made from vegetable oils, animal fats or recycled greases. Biodiesel can be used as a fuel for vehicles in its pure form.

The U.S. Department of Energy intends to replace 30% of the fossil fuel used annually in the United States for transportation with biofuels by 2030. Tree farms are an ideal solution to meet that goal. Our high-yield, short-rotation tree farms need less fertilizer and less energy to produce than traditional row crops. And they produce greater energy output per unit in the production of cellulosic ethanol.

Waste-to-energy has become synonymous with incineration. Modern incinerators can also reduce the volume of the original waste by 90%, depending upon composition and use of outputs.

Unlike the older designs, modern incinerators incorporate air pollution control systems and continuous emissions monitors.
