“…Due to the growing carbon dioxide emissions and fossil fuel depletion that are causing significant environmental issues, alternative carbon sources should be considered in the light of a sustainable energy economy [8][9][10][11][12][13][14][15][16][17][18][19][20]. In this concern, biomass is considered an attractive low carbon source for various energy or chemical options due to its potentially low greenhouse gas emission.…”

The anaerobic digestion (AD) of organic fraction municipal solid wastes (OFMSW) is a well-known technology for the valorization of wastes with the production of biogas, the latter usually used in power plant. Nevertheless, more and more effort is necessary in order to produce energy and chemicals from renewables as a strategy for replacing fossil fuels and reducing carbon dioxide in the atmosphere. In particular, methanol is considered as a promising energetic vector of the future since it may be produced from renewables and it may be used as a reactant for fuels and chemical production. Currently, methanol is industrially produced via syngas conversion using natural gas as the main feedstock. Biomethane produced in AD unit may be used as an alternative to natural gas for production of syngas that may be used for methanol production. In this work, a techno-environmental assessment for methanol production from biogas is presented and discussed, with focusing on the effect of side-unit, e.g. biomass gasification, carbon dioxide capture and renewable hydrogen production, on the environmental impact. Results show that highest CO2 saving is calculated for the biomass-integrated plant, although more detailed investigations, e.g. cost analysis, need for a proper assessment.

Production of energy or chemicals from biomass and several waste substrates appears a concrete strategy for replacing fossil fuels and reducing carbon dioxide emissions in the atmosphere. In particular, methanol from biomass or bio-waste is considered a reliable energy vector and key intermediate for industrial chemistry. Currently, methanol is industrially produced via syngas conversion using natural gas as the main feedstock. Biomethane produced via anaerobic digestion (AD) of Organic Fraction Municipal Solid Wastes (OFMSW) may be used as an alternative to natural gas for production of syngas with optimal composition via commercialized reforming processes. In this work, a technoenvironmental assessment for methanol production from biogas is presented and discussed. In particular, three case studies were assessed to minimize the environmental impact of biomethanol production.

Design of biorefineries has been often addressed by process flowsheet optimization tools without adequately considering the local biomass availability. In particular, the optimal plant size does not depend simply on the economies of scale, but also on the biomass feedstock availability and the topology of the territory affecting logistics costs. On the other hand, works aiming at the supply chain optimization consider literature data or approximate correlations to estimate biorefinery technical performance, capital and operating expenditure. The analysis of the biomass availability was developed in the framework of the Basilicata region where residual straw appears to be the most abundant product with an overall production of 400 kton/y. The paper also describes the current value chains and provides some potential scenarios for the conversion to biobased products. In particular, two biobased biorefineries were considered: case 1) production of fuel grade ethanol through the sugar platform; case 2) co-digestion of biomass feedstocks to produce biomethane. The analysis indicated that in the Basilicata region the fuel grade ethanol production offers concrete advantages in terms of CO2 reduction. On the other side, mixed feeding of biogas plants produces a biofuel with a higher energy density thanks to the increased plant production, but lower CO2-equivalent savings.
