Quantifying the economic potential of a biomass to olefin technology
… be used to conserve oil is worth studying. Biomass waste to olefin (WTO) technology replaces the use of oil as a feedstock. WTO technology is actually a combination of two different processes: the waste to methanol (WTM) process and the methanol to olefins (MTO) process. However, WTO …

Biomass Integrated Gasification Combined Cycles (BIGCC)
Conversion of biomass to energy does not contribute to the net increase of carbon dioxide in the environment, therefore the use of biomass waste as a clean and renewable fuel source is an attractive alternative to the use of fossil fuels. Biomass can be converted to energy via direct combustion or …

Expanding Circular Bioeconomy and Carbon Sequestration in British Columbia
… the circular bioeconomy in B.C. by viewing biomass waste as an economic and environmental opportunity to create usable by-products like biochar to reduce landfill methane and lifecycle emissions, create saleable products for local governments through industrial ecologies. A case study was …

Developing electrochemical methodologies towards addressing challenges in flow energy conversion technologies
… while producing valuable chemicals from biomass waste. Beginning with fundamental interfacial characterization, an SECM-based spot analysis methodology was established that quantifies heterogeneous electron transfer kinetics and identifies deviations from ideal electrochemical behavior at …

Design of a mobile torrefaction reactor for in-situ conversion of agricultural waste to solid biofuel
Significant volumes of biomass waste are generated each year as a result of agricultural practices in India. Despite the negative environmental impacts, in-situ incineration of crop residues is common practice for disposal of this waste. Transportation of raw biomass accounts for a significant …

Removal of acid-extractable organics from oil sands process-affected water using carbon-based adsorbents
… AEO from OSPW. Canada has abundant resources of biomass waste materials to prepare biochar and activated carbon (AC), which can be applied for the removal of AEO from OSPW. In this thesis, the impact of biochar and AC properties, and synthesis methods for the removal of AEO from OSPW have been …

Co-gasification of biomass and plastic waste in a bubbling fluidized bed reactor
… demonstrated the importance of reducing plastic waste and is believed to be responsible for increasing the generation of plastic waste by 54,000 tons/day which was reported in 2020. Another widely available waste is biomass waste. Agriculture and agroforestry, forest and wood processing, …

Energy efficiency in dual fluidised bed fast pyrolysis
… the University of Pretoria for the conversion of biomass waste to biofuels. The dual fluidised bed design allows in situ catalytic upgrading of bio-oil, by providing the conditions required for the regeneration and decoking of catalysts. The first version of the CRIPS process (CRIPS 1) emphasised …

PROTEIN HYDROLYSATES FROM AGRICULTURAL WASTE BIOMASS: ENZYMATIC PREPARATION, BIOLOGICAL ACTIVITIES AND TECHNO-FUNCTIONAL PROPERTIES
… – crude oil, coal and natural gas – by renewable biomass as a sustainable feedstock for the manufacture of chemicals and fuels. However, research on biomass valorization has mainly focused on the conversion of the C-, H-, and O-containing fractions (i.e., carbohydrates, lignin and triglycerides), …

Co-adsorption of phenol and calcium from an industrial wastewater stream
… industries are large producers of industrial wastewater that contain both organic and inorganic pollutants that influence water quality and availability. Conventional wastewater treatment methods such as chemical precipitation and membrane filtration are not economical and environmentally …

GREEN CATALYTIC STRATEGIES FOR THE PRODUCTION OF BIOBASED BUILDING-BLOCKS
… roadmap towards a sustainable economy system. Biomass-waste valorization, in particular ligno-cellulosic wastes, and the use of sustainable processes are pillars of the green chemistry approach. Notably, biobased lactones can be valorized into new valuable molecules such as diols and amines …
