To grasp the biomass energy potential and the reutilization flow in Taiwan, an industry survey was conducted this year (2023). The results of this survey will not only serve as a reference for the Ministry of Environment’s Resource Recycling Department in formulating policies for biomass waste management and reutilization, but will also be used to help establish a national biomass industry database and biomass resource map. In the future, this database will allow for searches of various biomass resource information, and the map will enable searches for biomass geographic information and reutilization channels. To date, 526 questionnaires have been collected, covering industries such as agriculture, forestry, fisheries, livestock, food production, and feed manufacturing. The results of the survey provide insights into the types, quantities, and disposal methods of waste biomass produced in the county, which will aid in evaluating the resource recycling potential of biomass waste in Yilan County.
This project also aims to promote the concept of “Waste to Energy” by advancing the use of Solid Recovered Fuel (SRF) in the county’s waste-to-energy policies. The Ministry of Environment has developed "Technical Guidelines and Quality Standards for SRF Manufacturing," and Yilan County has implemented SRF verification and quality control measures. So far, six expert site inspections have been conducted at SRF manufacturing plants or reutilization facilities with potential to become SRF manufacturers. These inspections have focused on the reutilization methods for waste wood, operational techniques, environmental protection facilities, and suggestions for improving product quality, providing businesses with macro-level recommendations for operations or future transitions.
Currently, the Taiwan Cement Su’ao Plant is using SRF, having completed six expert site inspections. However, the Run Tai Yilan Dongshan Plant has not yet started using wood chips or SRF. The gasification furnace is still being installed, and SRF feeding will only commence after installation and trial operations for fixed pollution control permits are completed. The raw material storage area and the gasification furnace facility are currently under construction, with trial operations expected to be completed by the end of the year.
From January to November 2023, Taiwan Cement Su’ao Plant has used an average of 733 metric tons per month of SRF (170044) and 1,804 metric tons per month of wood chips (140017).
As part of this project’s efforts to promote the recycling of other materials, it also seeks to address the issue of old fishing boats occupying berths at fishing ports. To encourage the deconstruction of old fishing vessels, applications for fishing vessel deconstruction have been processed. However, many fishing boats are made primarily of fiberglass, which is strong and durable. The project offers preliminary recommendations on potential recycling channels or technically feasible reutilization methods to enhance recycling rates and promote sustainable resource circulation.
In cooperation with the Ministry of Environment, the project conducted a demonstration of the fine crushing and recycling of waste fiberglass (FRP) and wood mixtures from decommissioned fishing boats on April 25, 2023, at Xingfu Cement’s Dong’ao Plant. The crushing process used two machines (coarse and fine crushers), which first crushed the FRP and wood mixture dismantled from the fishing boats. The materials were then further crushed to particles smaller than 3 cm by Xingfu Cement and fed into the rotary kiln for reutilization.
Current challenges related to waste vessel processing include high processing costs, long-term retention of waste vessels in ports, lack of suitable pre-processing facilities, and challenges in recycling these waste materials. To understand the current state of waste vessel processing and common issues, interviews were conducted with the Yilan County Marine Fisheries Institute and the Su’ao Fishermen's Association. Currently, seven decommissioned fishing boats in the county have completed deconstruction applications, with three more pending. According to officials, one of the key challenges in processing waste fishing boats is the high cost of disposal, and the difficulty of sorting and processing the various types of waste materials generated after dismantling. The project has compiled recommendations on potential disposal channels and reutilization methods, offering solutions to the problem of old fishing boats occupying berths, thus facilitating resource recycling and reutilization.
