由廢棄物到資源:建設業的循環型經濟的實踐 Waste to Wealth: Circular Economy Practices in the Construction Industry
出版日期: 2014年09月29日 內容資訊: 英文 23 Pages
簡介

建材產業現在在強化廢棄物處理法規及垃圾掩埋地不足的背景下,被迫轉變為為處理大量建築廢棄物的循環型經濟。其結果便是促進將廢棄物轉換成建材和其他用途之有價值資源的材料的資源回收技術便吸引了市場的注目。就具體的成本結構·獲利能力之案例來看,混凝土用骨材的情況利潤率最高,但有原料(混凝土廢棄物)供給穩定性的課題。低溫粉碎的輪胎再生也達到相當的利潤率,但預測回收業者如果不更加深入參與輪胎的製造工程,情況就無法獲得更進一步的改善。地毯的回收利潤率低,要解決該情形就必需提升消費者方面對資源永續性的關心,而支付更高價購買再生產品。

本報告提供建設業的循環型經濟──建築廢棄物的回收·再有效利用的可否和獲利能力──之應有做法相關分析,提供產業的環境變化,許多先行領域(地毯·混凝土骨材·輪胎廢棄物)的具體案例,彙整市場主要促進·阻礙因素,各種回收手法的成本結構·盈利比較等資訊,為您概述為以下內容。

目錄

The building material industry needs to adopt circular economy practices to handle the large volume of construction waste, given both increasing regulations on waste disposal and limited landfill space. As a result, material recycling technologies that convert waste into valuable feed resources for the building materials or other end-use applications are coming into greater focus. To determine the economic feasibility of the circular economy principles , we conducted case studies for recycling of three waste streams - carpet, concrete aggregates, and tire waste - and identified driving forces and barriers for each. We also built cost models and evaluated the profitability of recycling operators in these cases. According to these analyses, concrete aggregate recycling earns attractive profit margins, but faces the hurdle from the irregular supply of demolished concrete. Tire recycling by cryogenic grinding also generates decent margins, with even greater returns available if recyclers can improve the product's incorporation rate into tire manufacturing process. Carpet recycling has low margin and needs to target consumers with an additional sustainability goal and willingness to pay a price premium.

EXECUTIVE SUMMARY

LANDSCAPE

While a rising trend in the building material industry, the circular economy varies widely among sub-industries due to different regulations, value chains, market drivers, and barriers

ANALYSIS

Carpet, concrete, and tire recycling processes offer markedly different profit margins.
