219 Towards Maximizing Recycling Rate in Waste Plastics Liquefaction Plant

Fuels from Waste Plastics by Thermal and Catalytic Processes: A Review

“…In Japan, the share of feedstock recycling is fairly similar to that observed in Europe (2.7%). 5 The current unfavorable situation of feedstock recycling is mostly based on the high investments costs of recycling treatments. 6 For instance, the cost of the use of plastic waste in blast furnaces and coke oven furnaces is estimated to be 50-80 yen/(kg plastic), whereas, for liquefaction, the cost is ∼80-100 yen/(kg plastic).…”

“…8 Similarly, two plants are currently operated in Japan: the first is located in Niigata (6000 t/yr) 9 and the second one is located in Sapporo (14800 t/yr). 5 The technology currently is mature enough to be provided commercially by several companies, H.SMART, Inc. 8 and Ozmotech, 10 respectively. Consequently, liquefaction technology using thermal/catalytic pyrolysis toward fuels shows a promising future in the forthcoming years, especially considering the different technical solutions that exist to solve the problem of chlorine from residual PVC in the waste.…”

“…Presently, feedstock recycling only represents 2% of the total recycling effort, while mechanical recycling is the preferred recycling strategy (16%). In Japan, the share of feedstock recycling is fairly similar to that observed in Europe (2.7%) . The current unfavorable situation of feedstock recycling is mostly based on the high investments costs of recycling treatments .…”

“…Thus, in Poland, several plastics cracking installations have been built, the largest of them being located in Zabrze, with an estimated capacity of 145000 t/yr . Similarly, two plants are currently operated in Japan: the first is located in Niigata (6000 t/yr) and the second one is located in Sapporo (14800 t/yr) . The technology currently is mature enough to be provided commercially by several companies, H.SMART, Inc .…”
