Dealing with Byproducts

Wash Water Disposal
Responsibly dealing with spent wash water is not as hard as you might think.
Wash Water Treatment and DisposalWe can pour our wash water on the ground and kill the grass and pollute our streams or we can pour it down the drain and overload our sewage treatment plants. There is an alternative; we can treat our spent wash water and make it cleaner with a little effort. |
Productive Uses for Glycerin
The worst thing you can do is to horde glycerin. It is a fire hazard and there are just too many ways of turning this hazardous waste stream into a valuable co product.
Anaerobic DigestionOne way to turn a waste stream into a valuable energy product is to feed waste glycerin and spent washwater into an anaerobic digester. You can find a big digester at a sewage treatment plant or dairy farm or you can build your own personal digester. This is one of the few ways to dispose of glycerin that does not call for methanol recovery. |
Methanol Recovery from GlycerinThis still was posted on the infopop forum in 2005 by troy. It is one of the cleanest simplest stills for recovering methanol from glycerin that I've seen so far. |
Making Soap from Biodiesel GlycerinOne way to turn waste glycerin into something with value is to turn it into soap. In this article, Rick Knicely of Knice-N-Clean Soap Company discusses his way of making biodiesel glycerin soap. |
