Waste feedstock

The need to meet environmental regulations can affect processing costs. Undesirable air emissions may have to be eliminated and Hquid effluents and soHd residues treated and disposed of by incineration or/and landfilling. It is possible for biomass conversion processes that utilize waste feedstocks to combine waste disposal and treatment with energy and/or biofuel production so that credits can be taken for negative feedstock costs and tipping or receiving fees.

For anaerobic systems, methane gas is an important product. Depending on the type and nature of the biological components, different yields can be obtained for different biodegradable wastes. For pure cellulose, for example, the biogas product is 50% methane and 50% carbon dioxide. Mixed waste feedstocks yield biogas with methane concentrations of 40-60% (by volume). Fats and oils can yield biogas with 70% methane content.

Notably, an almost quantitative yield of DMC and 1, 2-diols can be attained under the optimized reaction conditions. Additionally, the catalyst is easily reused in almost consistent in yield and selectivity. This process eliminates the requirement for toxic and wasteful feedstocks such as phosgene and carbon monoxide and has successfully been applied to synthesize the other symmetric dialkyl carbonates and 1, 2-diols. 

Accelerate the development of feedstock collection and conversion technologies capable of using low-cost, waste feedstocks (including cellulosic materials).
