Greenhouse gas emissions from the treatment of household plastic containers and packaging: replacement with biomass-based materials.
نویسندگان
چکیده
The purpose of this study was to quantify the life-cycle greenhouse gas (GHG) emissions reduction that could be achieved by replacement of fossil-derived materials with biodegradable, biomass-based materials for household plastic containers and packaging, considering a variety of their treatment options. The biomass-based materials were 100% polylactide or a combination of polybutylene succinate adipate and polylactide. A scenario analysis was conducted considering alternative recycling methods. Five scenarios were considered: two for existing fossil-derived materials (the current approach in Japan) and the three for biomass-based materials. Production and waste disposal of 1 m(3) of plastic containers and packaging from households was defined as the functional unit. The results showed that replacement of fossil-derived materials with biomass-based materials could reduce life-cycle GHG emissions by 14-20%. Source separation and recycling should be promoted. When the separate collection ratio reached 100%, replacement with biomass-based materials could potentially reduce GHG emissions by 31.9%. Food containers are a priority for replacement, because they alone could reduce GHG emissions by 10%. A recycling system for biomass-based plastics must be carefully designed, considering aspects such as the transition period from fossil-derived plastics to biomass-based plastics.

Microalgal culture can be a combination of three environmental factors, treatment of wastewaters, production of renewable energy resources for replacement of fossil fuels and reduction of the greenhouse gas emissions. Microalga Spirulina is not just a good candidate forwastewater treatment (due to the ability toremove ofnitrogen andphosphorus), but also it plays a roleinreduction of greenhouse ...

This study examined the emissions produced during the pre-farm, farm and post-farm phases of the production cycle of raspberries and giant American whortleberries (blueberries) cultivated in one of the best-adapted areas in northern Italy. The pre-farm phase included the greenhouse gas emissions from the production of plants in the nursery and the transportation of the plants to the production ...
متن کاملGreenhouse Gas Emissions Accounting of Urban Residential Consumption: A Household Survey Based Approach
Devising policies for a low carbon city requires a careful understanding of the characteristics of urban residential lifestyle and consumption. The production-based accounting approach based on top-down statistical data has a limited ability to reflect the total greenhouse gas (GHG) emissions from residential consumption. In this paper, we present a survey-based GHG emissions accounting methodo...
