If food waste were a country, it would be the third-largest greenhouse-gas emitter, behind China and the U.S. Preventing it is one of our best opportunities to slow climate change. ... At Mill, we're creating a closed loop. You produce food scraps. We process them into food for chickens. (According to the EPA, feeding animals is the best use ...

 — Mill scale is the metallurgical waste produced by the rolling mill in the steel hot rolling process. It contains a substantial percent of iron, including traces of other elements.

Using state-of-the-art technologies, ethanol biorefineries convert grains, beverage and food waste, cellulosic biomass and other products called feedstocks into high-efficiency ethanol. Over 90 percent of the grain …

 — The two byproducts produced by the three-phase system are a solid residue known as olive press cake (OPC) and large amounts of aqueous liquid known as olive mill wastewater (OMW). The three-phase process usually yields 20% olive oil, 30% OPC waste, and 50% OMW. This equates to 80% more waste being produced than actual product.

 — Using this blend reduces the planet-heating pollution produced in cement manufacturing by 27%, according to Veolia. The program has processed 2,600 blades so far.

 — This results in the production of copious volumes of the liquid waste known as palm oil mill effluent (POME) [6, 7]. Estimates of the volume of POME produced per litre of palm oil extracted from palm fruits are few and variable. This is occasioned by several variables including differences in the efficiencies of the different processes and ...
