A review of Canadian wood conversion technologies for the production of fuels and chemicals

Canada has 347 million ha of forest cover, contributing to the potential large availability of wood‐based resources. Although Canada's forest sector contributed $23.7 billion to the national nominal gross domestic product (GDP) in 2019, the GDP contribution of the wood product manufacturing subsector shrank by 6%. To reposition the Canadian forest industry, new forest management practices and wood‐based conversion technologies should be applied. In this context, the use of woody biomass in biorefineries to produce clean energy, fuels, and chemicals is becoming increasingly significant. There is a need to understand the current status and challenges of the wood‐based biomass conversion technologies that have been and are being developed in Canada. This information will help decision‐makers in formulating and implementing forest sector‐related policies for a sustainable bioeconomy in Canada. This study is focused on a review of Canadian woody biomass conversion technologies. Our critical review identified considerable potential biomass conversion technologies specialized for woody feedstock, all in the Canadian setting. We focused on the prospects of revitalizing Canada's pulp and paper industry through the integration of pre‐treatment processes and biochemical technologies. The thermochemical conversion pathway was identified as the dominant route for woody feedstock valorization. The review also identified pathways with the potential to diversify the existing product mix that generate products from wood streams, such as chemicals and biomaterials. Most of the biochemical and thermochemical research done in institutional and multi‐institutional research collaborations from laboratory scale to industrial scale will boost the chances of the commercialization of a wood‐based biorefinery in Canada.

“…All of them contain RES (mainly PV but sometimes also wind sources) and EESs, especially batteries. For example, such systems have been examined to power the University of Victoria campus (Esfilar et al 2021) or to cover the demand of part of tVancouver (Bagheri et al 2018). Digesters (Singh and Basak 2022) and fuel cells and hydrogen storage instead of batteries (Zahedi et al 2021) have also been tried.…”

This paper presents the results of modeling and analysis of hybrid generation system (HSW). The system contains municipal waste gasification installation, photovoltaic (PV) system and wind farm. The system cooperates with the power system to provide electrical energy to the communal consumer. The consumer is characterized by a maximum power demand equal to 10 MW and an annual energy demand of 42.351 GWh. Generation with renewable sources was modelled using meteorological data. Moreover, in order to cover the demand with the level of generation, gas storage was used. Next, the three-stage gasification model is presented. It was validated, using the literature data, and its efficiency and gas composition have been calculated and are presented. Furthermore, energetic and economic analysis have been conducted. Installed power usage factor and efficiency of energy sources were calculated. Gross and net energy generation of hybrid generation systems have been computed and are presented. In this analysis, energy consumption by gas compressing was included. The analyzed HSW covered 54.5% of the demand. Most of this (30.2%) was covered by the gasification system. However, the system was characterized by a low net efficiency equal to 16.7%. Diagrams of power generation in each source and storage fill chart are presented. In the 56 economic part of the analysis, results of calculations of net present value and payback period are published in order to examine the profitability of the system. The cost of electricity was 490-1050 PLN/MWh. The results show that municipal waste gasification can be used as a part of HSW to adjust the generation with the demand. Moreover, it can be economically advantageous. However, it is characterized by high CO 2 emission and low efficiency of the waste processing system.

Food waste is a significant environmental issue today, as it contributes to depleting natural resources and greenhouse gas emissions from improper management. To address this, alternative food waste management and recovery strategies must be developed to promote nutrient recirculation and move towards decarbonization. University campuses could play a crucial role in pioneering such strategies, through pilot studies and implementation of effective waste management. The aim of this study is to devise a food waste management strategy that provides a more circular and decarbonized economy. A case example was developed based on ITU Ayazağa Campus, Turkey, with annual separated food waste of 577 tonne per year. A Life Cycle Assessment was conducted using the EASETECH software. Four scenarios were evaluated: anaerobic digestion, composting, incineration, and landfill. Of these, incineration resulted in the highest CO2‐eq savings, but lacked decoupling and circularity of resources. Conversely, anaerobic digestion demonstrated the highest circularity and lowest toxicity. Based on these findings, anaerobic digestion was selected for further investigation. Economic transactions for the anaerobic digestion system's business models were analyzed, including revenues, municipality fees, and operating costs. The new economic model is expected to align with circular economy strategies and promote stakeholder collaboration as a significant social outcome.
