“…Given the need to prevent and manage construction waste, several countries have developed and implemented a great number of environmental regulations, which specify limits for disposal in landfills, recycling goals, disposal fees and incentives to good waste management performance in construction projects [3,[6][7][8]. Consequently, contractors must take active waste prevention, reduction, environmental, economic and social benefits, through material, energy and information exchange (IS) [39].…”

The need for effective construction waste management is growing in importance, due to the increasing generation of construction waste and to its adverse impacts on the environment. However, despite the numerous studies on construction waste management, recovery of construction waste through Industrial Symbiosis and the adoption of other inter-firm practices, comprised within Industrial Ecology field of study, have not been fully explored. The present research aims to investigate Industrial Ecology contributions to waste management in industrial construction. The waste management strategies adopted in two industrial construction projects in Brazil are analyzed. The main waste streams generated are identified, recycling and landfilling diversion rates are presented and waste recovery through Industrial Symbiosis is discussed. A SWOT analysis was carried out. Results demonstrate that 9% of the waste produced in one of the projects was recovered through Industrial Symbiosis, while in the other project, waste recovery through Industrial Symbiosis achieved the rate of 30%. These data reveal Industrial Symbiosis' potential to reduce landfilling of industrial construction wastes, contributing to waste recovery in construction. In addition, results show that industrial construction projects can benefit from the following synergies common in Industrial Ecology place-based approaches: centralized waste management service, shared waste management infrastructure and administrative simplification.Sustainability 2017, 9, 1251 2 of 17 recycling and management actions within construction projects to deal with the various kinds of waste generated [2,9] and to assure legal compliance.Researchers have pointed out that waste management in construction activities should start from the design and the procurement phases and, then, extend to onsite technologies and plans [10]. Project designers should spend some time on considering how to reduce waste generation through reasonable design schemes [11], use of secondary materials [12], as well as, standardization of construction materials, dimensional coordination and application of modern methods of construction [13].In turn, regarding onsite management activities, adherence to design documents, reduction of the number and extent of design changes [13] and more accurate estimation of materials required in each construction stage [14] have been pointed as practices with great potential to reduce waste generation. Onsite management of construction waste is also considered determinant for its destination [15]. Waste segregation [16] and maximization of onsite materials reuse [17,18], for example, are practices that contribute for reducing waste landfilling and material intensiveness in construction. The importance of waste management plans to effective waste management in construction projects is also recognized [13], although its dissemination to all workers is one of the least widespread practices in construction [12]. The relevance of adequate supervision of waste management activities an...

“…Huang et al [13] reported that at present, the majority of Chinese recycling enterprises are in fiscal deficit, and it is urgent to provide appropriate economic incentives to promote the recycling market, such as financial subsidies for the improvement of recycling technology. Ajay et al [14] concluded that legislation on waste management can effectively promote the recycling of CDW and proposed policy measures whereby substantial CDW can be diverted from the landfill. Jia et al [15] introduced a subsidy mechanism for cases of low recovery and reuse ratios and found that subsidies can significantly increase the amount of waste recycled and reused.…”

The generation of construction and demolition waste (CDW) is a problem for societies aspiring to sustainability. In this regard, governments have the responsibility to support the CDW recycling through subsidies. However, the information asymmetry, as well as the “dynamic nature” of the CDW recycling market, results in a number of barriers for the government to promote CDW recycling. In this paper, we establish a mathematical model that includes the government and the recycling enterprise in the presence of dual information asymmetry including the unknown recycling technology level and unobservable recycling efforts in one-stage and two-stage cooperation. Using the incentive theory, the static and dynamic optimal recycling incentive contracts of the government were designed, and the optimal decisions of the recycler were identified. A numerical simulation revealed that by designing reasonable contracts, the government can encourage the recycler to report the true technical level and achieve information screening. Furthermore, the subsidy of the high-tech recycler remained unchanged under different circumstances. However, the subsidy of the low-tech recycler was closely related to the probability of misreporting and the proportion of technology types. This finding suggests that the government and recycler are inclined towards long-term dynamic cooperation.

“…Two primary environmental rationales for material recycling that pervade public and scholarly discourse are disposal reduction and reduction of virgin production from raw materials (Ackerman ) . It is commonly accepted in both scholarly literature and public discourse that material recycling reduces disposal by landfill or incineration by “diverting” end‐of‐life material to alternative productive uses (e.g., Ajayi and Oyedele ; Assamoi and Lawryshyn ; CalRecycle ; Morris ; Mueller ; Smith ). Landfill reduction was historically important due to perceived landfill capacity shortages (Ackerman ; Melosi ) but remains important today due to the significant methane and emissions from organic materials such as paper and textiles (e.g., Karanjekar et al.…”

In regions without modern solid waste management infrastructure or where humans may interact with landfills, their impact is even higher, and therefore the benefit of landfill avoidance is greater (e.g., Agamuthu and Fauziah 2011).…”

Material Recycling and the Myth of Landfill Diversion

Summary Proponents of material recycling typically point to two environmental benefits: disposal (landfill/incinerator) reduction and primary production displacement. However, in this paper we mathematically demonstrate that, without displacement, recycling can delay but not prevent any existing end‐of‐life material from reaching final disposal. The only way to reduce the amount of material ultimately landfilled or incinerated is to produce less in the first place; material that is not made needs not be disposed. Recycling has the potential to reduce the amount of material reaching end of life solely by reducing primary production. Therefore, the “dual benefits” of recycling are in fact one, and the environmental benefit of material recycling rests in its potential to displace primary production. However, displacement of primary production from increased recycling is driven by market forces and is not guaranteed. Improperly assuming all recycled material avoids disposal underestimates the environmental impacts of the product system. We show that the potential magnitude of this error is substantial, though for inert recyclables it is lower than the error introduced by improperly assuming all recycled material displaces primary material production. We argue that life cycle assessment end‐of‐life models need to be updated so as not to overstate the benefits of recycling. Furthermore, scholars and policy makers should focus on finding and implementing ways to increase the displacement potential of recyclable materials rather than focusing on disposal diversion targets.
