Biorefinery-Derived Bioplastics as Promising Low-Embodied Energy Building Materials

摘要: Petrochemical-based plastics that are used in building construction produce hazardous non-biodegradable wastes after demolition of the buildings or temporal constructions create logistics and disposal problems. Recent investigations on bio-based reveal opportunities for a new sustainable material made from renewable organic sources due to biodegradability can be left soil composted because biodegradability. Bioplastics also have potential lead rise materials with low-embodied energy, thus contributing energy efficiency. However, current cost pure bioplastics is higher than petrochemical plastics. To improve efficiency bioplastics, inexpensive raw needed. Potential feedstocks production include negative-, zero- low-cost by-products acidogenic fermentation, pyrolysis oil lignocellulosic biomass waste, fractions municipal solid reject waters, primary secondary sludges wastewater treatment plants, mention few. Cost reduction achieved through cost-efficient fermentation technologies based continuous septic cultivation mixed bacterial cultures crude composite as energy.
