This project included 4 purposes: investigating foreign recycling regulations, analyzing industrial trend and waste flow, calculating recycling subsidy and conducting a survey of ULAB (used lead-acid batteries) recycling process and technology abroad. The following shows results of this project:
1. Investigating foreign recycling regulations
Companies or associations are main units which conduct and operate ULAB recycling affairs. Instead, governments merely legislate among investigated countries, such as the U.S., Japan, Korean, China and the U.K. The advanced process technology of the ULAB is de-sulfurization before smelting, which is soaked in electrolyte and result in reducing oxysulfide and increasing lead capacity. Because of higher cost and more extensive factory area, government could establish economic tool and modify approval procedures to raise recyclers’ intention to improve equipment.
2. Analyzing industrial trend and waste flow
This research includes 2 parts, 1. Analyzing industrial trend: we estimated put on the market (POM) through government’s database, GDP at 84,490,165 and 86,070,131kg in 2016 and 2017, separately. We also calculated collection rate; it could be 97% in 2016 and cause lower found surplus, therefore it should be examined soon. 2. Analyzing waste flow: per the result, about 94.49% ULAB would be recycled. Non-recycled ratio was 5.51%. It included reuse: 0.82%, export: 1.27 %, however. Consequently, the ULAB proper treatment ratio was 96.58% in Taiwan.
3. Calculating recycling subsidy
According to the results from the calculations of the recycling fee factors 2014 and 2015, we found recyclers could make a profit without subsidy. Therefore, we involve pollutant control fee to calculate recycling fee and differential subsidy. The index of differential subsidy was the lead capacity divided by all product after smelting. When it was more than or equal to 97%, subsidy of normal ULAB was NTD 0.80 per kg and special ULAB was NTD 4.05 per kg. If the ratio was between 89% and 96%, the subsidies were NTD 0.45 and 3.70 per kg, separately; if it was less than 89%, the subsidies both were NTD 0. The recycling fee was floating by calculating collection rate. When collection rate was 95%, the fee would be NTD 1.56 per kg. After installing system of floating recycling fee and differential subsidy, it could help found to rise to proper surplus.
4. Contacting a survey of ULAB recycling process and technology abroad
There were 3 types units for this survey abroad, recycling organization, recycling research institute, waste tire recycler. Through this survey, we could understand the regulation of waste tire and ULAB recycling in Japan, the result of operating recycling and the technology of treating waste tires as fuel. The result of survey also could be references to improve Taiwan’s recycling strategy.
