Areas on which to focus when seeking to reduce the greenhouse gas emissions of commercial waste management. A case study of a hypermarket, Finland.

摘要: Abstract This study focuses on commercial waste, which has received less attention than household waste in regards to greenhouse gas emission research. First, the global warming potential (GWP) of management was calculated. Second, impacts different fractions and processes were recognised. Third, key areas focus when aiming reduce emissions determined. conducted generated by a real hypermarket South-East Finland included eight fractions. The treatment plants selected based actual situation. Three scenarios employed evaluate environmental impact managing mixed waste: landfilling, combustion more accurate source separation. GaBi software assessment methodology CML 2001 used perform life cycle associated with management. results indicated that total GWP could be reduced 93% directing instead landfill. A further 5% reduction achieved separation waste. Utilisation energy had most significant influence (41–52%) (−880 −860 kgCO2-eq./t), followed landfilling (influence 15–23% GWP, 430 kgCO2-eq./t), recycling polyethylene (PE) plastic 18–21% −1800 kgCO2-eq./t) cardboard 11–13% 51 kgCO2-eq./t). should placed substitutions, especially terms substitutions PE plastic. also clarified importance sorting plastic, even though share this fraction not substantial. paper compared those previous studies. output analysis can significantly identifying an alternative or incineration location for where it is substitute virgin material replace fossil fuels respectively. In conclusion, essential note companies have notable because they choose places at are treated utilised.
