Towards circular economy: integration of bio-waste into chemical supply chain

Recovery of Arenes from Polyethylene Terephthalate (PET) over a Co/TiO2 Catalyst

“…[4] The typical plastic waste management techniques such as landfill and incineration are convenient for the treatment without sorting, but these disposals invade valuable land space and release toxic air pollutants. [5] Recycling, instead of landfills and incineration, is an alternative way to handle the problem, which better fits into the concept of circular economy [6] and holds the potential to recover valuable chemicals from plastic wastes. [7] Polyethylene terephthalate (PET), a synthetic aromatic polyester, is formed from terephthalic acid (TPA) and ethylene glycol.…”

Chemical data intelligence for sustainable chemistry

“…2 To tackle the problem, research efforts shifted towards studying the utilization of renewable feedstocks within chemical industries, such as cellulose, 3 lignin, 4 chitin, 5 or bio-wastes. [6][7][8] In recent decades, the scientific community developed new reactions and engineering techniques to produce various value-added chemical compounds from renewable feedstocks. 5,[9][10][11] However, one of the main problems when developing sustainable processes is the lack of access to information on all multiple co-existing options, hindering a systematic way to shape early, but key process decisions.…”

Evaluation of the influence of olive mill waste on soils: the case study of disposal areas in Crete, Greece

“…Without ignoring the importance and contribution of various organic waste treatment technologies in maintaining environmental quality, the current approach focuses on the utilization of organic waste and moving to a more cyclic way of implementation as regards the management of materials and resources [3,18]. In light of these facts, many researchers and policy makers promote the reuse of OMW for irrigation and fertilization purposes [19].…”
