Use of reverse osmosis concentrate for mitigating greenhouse gas emissions from pig slurry.

Due to the high global warming potential (GWP) in a short time scale (GWP100 = 28 vs. GWP20 = 86), mitigating CH emissions could have an early impact on reducing current global warming effects. The manure storage tank emits a significant amount of CH, which can diminish the environmental benefit resulting from the anaerobic digestion of manure that can generate renewable energy.

Alkaline pretreatment improves saccharification and ethanol yield from waste money bills.

Waste money bills (WMB) is a by-product of the money making process that consists of rich-cellulosic material for many biotechnological applications. This waste money bills is unusable and usually exhausted. Saccharification was improved using various concentrations of sodium hydroxide, NaOH (0.

Influence of torrefaction pretreatment for ethanol fermentation from waste money bills.

Waste money bills (WMB) that are no longer legal tender are nonrecyclable and are generally useless. In this work, we used this cellulose-rich material for ethanol fermentation for the first time. Torrefaction of this nonlignocellulosic waste material was attempted to examine whether such material could benefit from this process as a conventional lignocellulosic material does.

Effect of torrefaction for the pretreatment of rice straw for ethanol production.

Background: Rice straw is an attractive lignocellulosic material for ethanol production, since it is one of the most abundant renewable resources. It generally has high cellulose and hemicellulose contents that can be readily hydrolysed into sugars for subsequent ethanol fermentation. The pretreatment method plays an important role in increasing the efficiency of enzymatic saccharification, thereby making the whole process economically viable.
