Bulk chemicals from biomass
Given the current robust forces driving sustainable production, and available biomass conversion technologies, biomass-based routes are expected to make a signifi cant impact on the production of bulk chemicals within 10 years, and a huge impact within 20–30 years. In the Port of Rotterdam there is a clear shortterm (0–10 year) substitution potential of 10–15 % of fossil oil-based bulk chemical...
متن کاملSpill hazard evaluation for chemicals shipped in bulk using modeling
A wide variety of chemicals are shipped in bulk world-wide, raising concerns regarding the ecological and human health risks of spills of hazardous materials. A screening analysis was performed, using the chemical spill model CHEMMAP to estimate the expected fate and concentrations of chemical in water resulting from a spill into a large estuary and the potential ecological hazards to aquatic b...
متن کاملBioremediation Treatability Studies for Soils Containing Herbicides , Chemicals and Petroleum Products
Many organic chemicals have known human and environmental health hazards. At sites where chemicals have historically been stored, mixed and transferred, spills have often occurred. A primary route for human exposure to hazardous chemicals is by drinking groundwater which has been contaminated due to spills onto soil (Wilson et al., 1986) Due to the potential human health risks associated with e...
متن کاملDivers’ Detergents Are Different
As anyone who has ever blown bubbles as or with a child knows, if you stop blowing before the sphere is complete, it collapses and disappears. The gas exchange surfaces of our lungs, the alveoli, are also highly curved, thin-walled, moist membranes that are open to the atmosphere. They too, would tend to go poof! and disappear, save for a mixture of phospholipids and proteins that lines the epi...
متن کاملAction of Synthetic Detergents
The bactericidal and bacteriostatic actions of soaps have been recognized for many years. Detailed studies by Eggerth (1) on the germicidal action of soaps have shown the importance of such factors as length of hydrocarbon chain, chemical configuration, effect of hydrogen ion concentration, effect of serum, etc. Avery (2) demonstrated the selective germicidal action of soap on microorganisms, a...
