Households and industries produce enormous amounts of mixed, heterogenous waste streams containing organics and inorganics. With respect to the organics, some are biodegradable, while others are not and often plastics. This mixture creates challenges for various current solid waste management processes. An integration of different platform technologies is required to effectively dealing with this low grade solid waste. This project aims to assess the technical feasibility on turning low-grade, heterogenous organic and plastic wastes into high value chemical streams via integrating thermo-chemical and biological platform technologies with a high technological readiness level. The assessment will be done based on synergetic experimental work on tuneable pyrolysis and microbial chain elongation technologies that will potentially lead to new integration of these platforms for an effective urban solid waste management.
