At least half of waste is industrial and commercial. Sources range from manufacturing, construction, and mines to restaurants, office buildings, and schools. The stream of waste they produce is diverse; not all of it can find a second life, but much can. Industrial and commercial recycling reduces emissions when new products are made from recovered materials, rather than virgin resources.
A suite of strategies can enhance recycling rates:
- Extended producer responsibility laws make companies responsible for managing goods post-use—an incentive to make products that are longer lasting, easier to fix, and as recyclable as possible.
- Marketplaces for secondary materials facilitate the exchange of recyclable and reusable goods.
- Innovation in conversion technologies makes more materials recyclable.
- Circular business models transform the dominant industrial approach of take, make, waste—recapturing “waste” as a valuable resource.
Recycling needs to be one piece of an integrated approach, that also includes making more efficient use of materials and extending product life. Together, they can reduce emissions from extracting, transporting, and processing raw materials. Because society currently uses far more of these materials far more quickly than the earth can regenerate, such practices address parallel challenges of resource scarcity.

Project Drawdown defines industrial recycling as: the increased recovery of recyclable materials, not including paper and not including organic materials, from the commercial and industrial sector of the economy. This solution replaces the disposal of recyclable materials in landfills.
Recovering and recycling industrial and commercial waste materials for use in new products reduces the amount of materials manufactured from virgin sources, produces less greenhouse gas emissions, and reduces the environmental burden created if the waste is disposed in overcrowded landfills. Waste considered in this solution is post-consumer waste, measured at waste collection centers.  Recyclable waste types considered for this solution are metals, plastic, glass and “other”.  Waste that is recyclable makes up nearly 37% of total municipal solid waste generated globally.
Municipal solid waste is defined differently by governments, organizations, and researchers; for this solution, all sources include both household and commercial waste in aggregate values reported. Because the fraction of total waste allocated to households and commercial or industrial waste generators is not often reported, it is assumed that 50% of recyclable waste is derived from the industrial sector. (US EPA, 1998)
Total Addressable Market 
The total addressable market for recyclable waste was calculated using a composite of forecasts, including a linear interpolation of World Bank data from 2010-2025, an extrapolation to extend those projections to 2050, and a per capita extrapolation using data from the Intergovernmental Panel on Climate Change (IPCC).  It is estimated that by 2050, global organic waste will be approximately 1459 million metric tons. Current adoption  of both household and commercial recycling at the year 2014 was estimated at 27% of recyclable waste (see Hoornweg and Bhada-Tata, 2012).
Adoption Scenarios 
Due to the lack of reliable future projections of the growth of recycling, three custom adoption estimates were developed based on increasingly ambitious recycling rates per region.  In the first estimate, all 2050 non-OECD regional rates are set to the 2014 OECD recycling rate of approximately 57%. In the second estimate, non-OECD countries’ recycling target rate for 2050 is set to the current Austrian recycling rate of 63%. In the third estimate, recycling rates for non-OECD countries, recycling rates in 2050 are set to correspond with the current best recycling rate of the country in the corresponding region. For example, Asia (sans Japan) region’s recycling rate target is set to 61%, which is Singapore’s recycling rate in 2015. From these estimations, adoption boundaries were created from which the Project Drawdown Scenarios were derived.
Impacts of increased adoption of industrial recycling from 2020-2050 were generated based on three growth scenarios, which were assessed in comparison to a Reference Scenario where the solution’s market share was fixed at the current levels.
- Plausible Scenario: In this scenario it is assumed that recycling will increase from present rates to 65% (pre-integration),  amounting to 941 million metric tons of recycled material in 2050 total and 470.5 million metric tons allocated to industrial recycling.
- Drawdown Scenario: In this scenario, complete optimization of source separation and collection processes as well as aggressive zero waste policy adoption are assumed. The amount of total recycled waste in 2050 is 984 million metric tons and 492 million metric tons allocated to industrial recycling (89.65% of the post-integration market). The scenario results in a mitigation impact of 6.05 gigatons of carbon dioxide-equivalent greenhouse gases.
- Optimum Scenario: This scenario considers the technical potential of the solution assuming a “zero waste” world by 2060, which targets a nearly universal adoption of recycling, with 813.52 million metric tons of recycled waste in 2050 (99% of the post-integration market). This results in a mitigation impact of 5.8 gigatons.
Financial results were reached by comparing the costs of creating and operating material recovery facilities or mechanical-biological treatment facilities to creating and operating sanitary landfills for an equivalent volume of recyclable waste. The cost of establishing new recycling facilities over the period in question is calculated to be US$2.4 trillion,  which is US$734 billion more than the cost of establishing new landfills. However, when revenues from recovered materials are included in comparison to the costs of virgin materials, operating recycling facilities costs less than operating landfills and sourcing virgin material feedstocks for industry.
For integration of the industrial recycling solution into the Materials Sector, Drawdown first considered the reduction of recyclable waste due the increased adoption of the assumed compostable fraction of bioplastics adoption. The recyclable fraction decreases year to year as the fraction of recyclable plastic used by humanity decreases, so that as the adoption scenarios become optimized the overall adoption of industrial recycling decreases, yet the adoption percentage increases. Additionally, adoption peaks at 99% of the market in 2048 in the Optimum Scenario and holds constant for the rest of the period.
Drawdown found a potential of 2.77 gigatons of emissions reduction in the Plausible Scenario over 2020-2050 corresponding to an 81% adoption of industrial recycling, with a net implementation cost of US$367 billion but a net lifetime operational savings of US$122 billion. For the Drawdown Scenario, the emissions avoided amount to 3.02 gigatons with a 90% adoption, and the Optimum Scenario would result in 2.9 gigatons reduced at an 99% adoption by 2050.
Household and industrial recycling are keystone elements of a circular economy that provides industry with feedstocks to produce needed goods with fewer emissions incurred. Recycling also generates unmeasured benefits by extending the life of sanitary landfills and creating economic opportunity and activity in material recovery and reprocessing.
The state of currently operating landfills and material recovery facilities could not be easily determined within the scope of this study. Because of the limitations to establish how much waste can be landfilled in currently operating landfills and how much of the capacity of currently operating material recovery facilities is not exploited to its full potential, first costs of such facilities are calculated for installing completely new facilities. Similar limitations of the study have been identified with establishing first costs of introducing new solid waste collection systems by municipalities, and the unused capacity of existing ones. Additionally, much of the complexity of recycling ceramics, rubber, textiles and e-waste have been oversimplified with the approach taken. Finally, it is also likely the development in the technologies of material recycling, product recycling and end-of-pipe technologies such as waste identification and sorting technologies, waste disassembly and shredding technologies and material recovery technologies will have positive impacts on lowering first costs and operating costs of recycling.
 Pre-consumer waste is found in far smaller amounts: only 10% of total waste generated by households, residential, commercial, and institutional subjects. Pre-consumer waste is also almost 100% recyclable on-site. The amount of pre-consumer waste that is lost from the material cycle is hence negligible (EU Joint Center 2002).
