據離岸工程網站3月31日消息 總部位于英國的海上可再生能源公司Catapult周三在一份報告中稱：“大規模回收風力渦輪機葉片是朝著實現海上風電產業零碳、零浪費、推動英國供應鏈增加2萬個就業崗位邁出的重要第一步。”

該可再生能源公司呼吁增加投資，并將研發工作徹底轉向風力渦輪機葉片回收利用，理由是海上風電的循環經濟方式給英國供應鏈帶來巨大的經濟機遇，這可能將該行業在英國創造就業機會的目標延長三分之一，從而多創造2萬個就業機會。

ORE-Catapult表示，從技術上講，風力渦輪機幾乎85-90%是可回收的，但它們的葉片由樹脂和纖維復合材料制成，在分解、加工和回收方面具有挑戰性，仍然是實現完全可回收的主要障礙。

根據一份與OGTC合作的ORE Catapult 報告，以及國家復合材料中心（NCC）和利茲大學專家的投入，14項技術顯示出回收葉片材料的希望，但在我們看到大規模部署之前，還需要進一步的工作，特別是圍繞環境影響、能源使用和熱解（復合材料熱處理）等技術的成本效益問題。

ORE Catapult表示：“這為英國公司提供了一個黃金機會，為我們的回收需求提供解決方案。據估計，到本世紀中葉，全球海上風電行業將需要停用85吉瓦的容量（包括325000片葉片）。雖然這些估計假設了目前25年的生命周期，但它們為該行業循環經濟先驅未來全球市場的規模提供了一個例證。”

UK: Offshore Wind Blade Recycling Could Create 20,000 Jobs

"At-scale recycling of wind turbine blades is an important first step towards achieving a zero-carbon, zero-waste offshore wind industry and boosting the UK supply chain by 20,000 jobs, " the UK-based Offshore Renewable Energy (ORE) Catapult said in a report Wednesday.

The ORE has called for increased investment and a radical shift in research and development into wind turbine blade recycling, citing the huge economic opportunities for the UK supply chain from a circular economy approach in offshore wind that could extend the sector’s UK job creation targets by a third, creating an extra 20,000 jobs.

Technically, ORE Catapult said, wind turbines are almost 85-90% recyclable, but their blades, made from composites of resins and fibers, have proven challenging to break down, process, and recycle, and remain the major hurdle to achieving fully recyclability.

According to a report which ORE Catapult produced in partnership with OGTC, and with input from experts at the National Composites Centre (NCC) and the University of Leeds, 14 technologies show promise for recovering blade materials but "further work was needed before we see them deployed at scale, particularly around issues of environmental impacts, energy use and cost-efficiency of techniques such as pyrolysis (heat treatment of composites)."

"This provides a golden opportunity for UK companies to provide solutions for our recycling needs. It is estimated that the global offshore wind industry will need to decommission 85GW of capacity (including 325,000 blades) by mid-century. While these estimates assume today’s 25-year lifecycle, they give an illustration of the scale of the future global market for circular economy pioneers in the sector," ORE Catapult said.
