The project period was from February 2nd, 2013 to December 31st, 2013, the main subjects included “database establishment of recycled container responsible enterprises”, “database establishment of announced recyclable items and enhancement of material distinguishing”, “collecting and investigating carbon footprint of the secondary production”, and the results were summarized as the following:
According to the recycled container sales volume reported by responsible enterprise in 2012, the database was established by the best-selling goods in all range of material taking a half of the top 20% amount of reported sales volume. In total, 126 data was set up for checking out undeclared enterprises in the future.
In addition, establishment of distinguishing process on non-plastic waste containers and announced recyclable waste plastic containers could provide a standard for enforcement authorities and recycling enterprises to follow. However, there were 22 uncertain cases about recycle symbol counted from sales database system (managed by EPA), such as particular plastic and complex plastic, recycle symbol marked at inconspicuous place, and unclear category.
This project had built local environmental protection authorities counseling access, and during the project, we collaborated with EPA to help local environmental protection authorities and environmental groups to learn more about non-foamed PS container distinguishing technique and treatment of OPS. Besides, we carried out a feasibility analysis and investigations on additional announced regulated containers which environmental groups claimed to add. Such as printer supplies, toner, and food packaging which contained PVDC.
This project has completed inspection of carbon emissions on PVC, PS and non-foamed PS, and auditing and certification volume of each material was up to 75%, therefore, these data was reliable for further study. Through the inspection of carbon emissions on secondary products compares with original materials, especially on PVC, PS and non-foamed PS, carbon reduction reaches 76% to 85% when using secondary products.
Furthermore, the carbon footprint coefficients for three materials (iron, aluminum and glass) had been established. Because we already had the electric power and diesel carbon emission coefficients. After inspection, the coefficients of three materials all meet the high data quality by calculation.
