Remediation is defined by Oxford Languages as the action of remedying something, in particular of reversing or stopping environmental damage. There are three types of remediation, and they are soil remediation, groundwater/surface water remediation, and sediment remediation. This post will focus on soil and sediment remediation. Soil remediation refers to the process of removing contaminants …
By : Branden Drew Fly ash is a by-product of coal fuel combustion. Clay is typically entrapped during the formation of coal. When coal is burnt, the incombustible clay particles are left behind as ash. In grate boilers, incombustible ash agglomerates as cinders through prolonged residence time. The ground clay escapes along with flue …
Coal fired power plants produce a variety of residual waste products from the combustion of coal in boilers, furnaces and incinerators. Two primary types of ash are those residuals. Fly ash is a light end, small and air borne particle that flies away hence the name “fly ash”. It is typically collected in a scrubber …
What is the Difference between bottom ash (a/k/a CCR) and fly ash? Read More
By: Branden Drew Methane is the second biggest factor in climate change by greenhouse gasses. Methane is produced by the decay of organic material and is produced primarily by natural gas and petroleum systems, enteric fermentation (digestion process of animals), landfills, and manure management according to the US Environmental Protection Agency (EPA). Enteric fermentation and …
By : Jeff Sayre Manure is the primary waste product from raising broiler chickens, laying hens and turkeys as well. It may be manure alone in a confined layer operation or co-mingled with bedding and feathers in other operations. The manure itself although “solid” in appearance is as much as 70% moisture yet it will …
The process of making paper pulp uses a lot of water which carries away the particulates that are too small to stick in the paper. The solids that are recovered from this wastewater are called paper and pulp residuals, and may contain mud, ash, or small paper fibers. These residuals are usually considered a waste …
What are the benefits of paper and pulp residuals? Read More
By: Jeff Sayre When operating a paper plant, reducing storage costs are vital to its overall production. The two primary factors in determining disposal costs of this waste stream are trucking and tipping fees. Since the waste product is over half moisture, a proper treatment technique can reduce disposal costs by at least half. A …
How can you reduce storage & disposal costs of Paper & Pulp residuals? Read More
By: Jolene Reddick One of the greatest challenges of society is climate change is the focus on how we can use biomass to displace fossil fuel resources. To consider this an option, you would have to look at resources; where are they, how costly they are and how much can be used to displace fossil …
Biomass is all the organic materials made from plants and animals. The word, “bio” means, “life” and the word, “mass” means “all things”. Biomass is a renewable source of energy. Which means, we can use biomass again and again, to generate energy. Biomass is important because it contains stored energy. How is biomass produced? Well, …
By: Jolene Reddick Frac sand mining is the mining of sand which is used in the fracking process to get oil and natural gas out of the ground. The frac sand industry isn’t necessarily a big industry in the large scheme of things, but Minnesota and Wisconsin have some of the best areas for frac …
