Recycling of Plastic

Christensen, Thomas Højlund; Fruergaard, Thilde

Solid Waste Technology and Management — 2011, pp. 220-233

, good strength and long durability. Recycling of plastic waste from production is well-established, while recycling of postconsumer plastic waste still is in its infancy. This chapter describes briefly how plastic is produced and how waste plastic is recycled in the industry. Quality requirements

Recycling of plastic: accounting of greenhouse gases and global warming contributions

Astrup, Thomas; Fruergaard, Thilde; Christensen, Thomas Højlund

Waste Management and Research — 2009, Volume 27, Issue 8, pp. 763-772

Major greenhouse gas (GHG) emissions related to plastic waste recycling were evaluated with respect to three management alternatives: recycling of clean, single-type plastic, recycling of mixed/contaminated plastic, and use of plastic waste as fuel in industrial processes. Source-separated plastic

Plastic recycling in the Nordics: A value chain market analysis

Milios, Leonidas; Holm Christensen, Lena; McKinnon, David; Christensen, Camilla; Rasch, Marie Katrine; Hallstrøm Eriksen, Mikael

Waste Management — 2018, Volume 76, pp. 180-189

There is low utilisation of plastic waste in the Nordic region and only a fraction of plastic materials go back into production processes through reuse and recycling practices. This paper aims to increase knowledge concerning factors that inhibit demand for recycled plastics, and to identify

Closed-loop recycling of plastics enabled by dynamic covalent diketoenamine bonds

Christensen, Peter R; Scheuermann, Angelique M; Loeffler, Kathryn E; Helms, Brett A

Nature Chemistry — 2019, Volume 11, Issue 5, pp. 442-448

Recycled plastics are low-value commodities due to residual impurities and the degradation of polymer properties with each cycle of re-use. Plastics that undergo reversible polymerization allow high-value monomers to be recovered and re-manufactured into pristine materials, which should incentivize

Circularity in Mixed Plastics Chemical Recycling Enabled by Variable Rates of Polydiketoenamine Hydrolysis

Helms, Brett; Demarteau, Jeremy; epstein, alexander; Christensen, Peter; Abubekerov, Mark; wang, hai; et al. (7 more)

Footwear, carpet, soft furnishings, automotive interiors, and multi-layer packaging are examples of products manufactured from several types of polymers whose inextricability poses significant challenges for recycling at end-of-life. Here, we show that chemical circularity in mixed-polymer recycling becomes possible by controlling the rates of depolymerization of polydiketoenamines (PDKs) over several orders of magnitude through molecular engineering. Stepwise deconstruction of mixed-PDK composites, laminates, and assemblies is chemospecific, allowing a prescribed subset of monomers, filler...

Science Advances — 2022, Volume 8, Issue 29, pp. eabp8823

Footwear, carpet, automotive interiors, and multilayer packaging are examples of products manufactured from several types of polymers whose inextricability poses substantial challenges for recycling at the end of life. Here, we show that chemical circularity in mixed-polymer recycling becomes
