Study on the Effectiveness of Two Biopolymer Coagulants on Turbidity and Chemical Oxygen Demand Removal in Urban Wastewater.

The present study investigated the effectiveness of two biopolymer coagulants on turbidity and chemical oxygen demand removal in urban wastewater. The biopolymers were produced from vegetal biomass using the mucilage extracted from cladodes, and leaves. is an abundant species in Mexico, which is not edible.

Evaluation of the lipase from castor bean ( L.) as a potential agent for the remediation of used lubricating oil contaminated soils.

Bioremediation of hydrocarbons-contaminated soils, using enzymes, is considered an alternative technology for soil remediation, obtaining shorter remediation times, greater removal efficiencies, and less waste generation. The lipases from invasive plants such as castor bean ( L.) could represent an opportunity for its application in this purpose.
