In order to review the declared recycling items, propose measures to enhance recycling, and evaluate the carbon footprints of recyclable wasted containers, this project has completed the following tasks.
First, the violation patterns and labeling of the declared waste containers, which are ought to be recycled, treated and reclaimed, was collected and built into a database with an index chart. Also, possibility and cost-benefit of adding new declared waste containers are evaluated. The research result shows that the waste container for Chinese herb is potential candidates to be declared as a new item.
Second, regarding to enhancing the recycling rates of those declared waste containers with poor recycling rate, this project collects and analyzes many successful cases in foreign countries for reference. We also evaluate the feasibility of requesting the vendors of drugs and pesticide to set up devices to enhance recycling rates.
Third, after visiting the subsidized factories to recycle, treat and reclaim various kinds of waste plastic containers, we are able to comprehend the current development of the reclamation industry for waste plastic containers. We propose three ways to improve the quality and value of recycled plastic materials: (1) to solve the labeling problem of PETG, (2) to improve the quality of recycled PP materials, and (3) to do research on PET alloys with recycled PET.
Last, this project has proposed a mechanism for on-site auditing, evaluating and data assembling the carbon footprints and carbon emissions of those declared containers, including containers made of PP, PET , aluminum and glass. This project also compares the difference of carbon footprints between raw and recycled material, and calculates the carbon footprints of the products which are made of or from recycled materials.
