Heavy metal accumulation on microplastics in compost - The role of biofilm

Detritus, Год журнала: 2024, Номер 26, С. 27 - 35

Опубликована: Март 31, 2024

Microplastics, small plastic pieces ( microplastics washed with distilled water > compost free from chemically separated microplastic new macro-plastic, some exceptions. Heavy metal concentrations were significantly higher in samples Kochi, due to a larger bio-film formation on the plastics as determined by TOC and SEM analyses. The findings of study highlight importance source segregation prevention mixing organic waste MSW, avoid heavy transport terrestrial environment through microplastics.

Chemical Recycling of Plastic Waste from Different Polymers: New Trends

BioScientific Review, Год журнала: 2024, Номер 6(1), С. 34 - 53

Опубликована: Май 9, 2024

Background For decades, the amount of global plastic waste has been increasing at an alarming level. Traditional landfill and incinerator treatments, on other hand, result in air pollution wastage valuable land. Method This study examined recent advances recycling recovery waste. A special emphasis was placed trash derived from polyolefinic sources, which accounts for a substantial part products used daily lifecycle. The mechanical chemical systems technologies treatment were detailed explored this study. To ensure comprehensive study, sixty-five (65) papers carefully selected. selected published during period 2015-2023. These searched using web search engine Google Scholar PubMed database reviewed to derive meaningful insights. Results findings determined that is critical possibility reduce marine terrestrial enable idea circular economy be implemented today's world. Plastic poses both obstacles opportunities communities, independently their level environmental awareness or technical advancement. Moreover, processes utilize variety as feedstock. Depending source, shape, usage, these can reduced size more acceptable shape form (pellets, flakes, powders). Conclusion Advanced thermo-chemical methods encompass wide range produce either fuels petrochemical Although schemes are well known commonly used, many techniques productive widely due economic benefits.

Use of the Organic Fraction of Urban Solid Waste to Recover Degraded Areas in Chilca, Peru

Polish Journal of Environmental Studies, Год журнала: 2024, Номер unknown

Опубликована: Июль 19, 2024

The treatment of municipal solid waste (MSW) in Peru and some parts the world is still incipient, mainly due to lack technologies implemented recover this waste; another important cause studies for organic fraction (OFMSW).The objectives work were: (i) determine generation OFMSW, (ii) produce quality compost (iii) estimate application rate recovery degraded surfaces.Tools instruments acquired from Institute Sanitary Engineering FIUBA Ministry Environment were used measure physicochemical parameters environmental estimates.The results showed a per capita MSW 0.472 kg/inhab/day, which 42.87% was composed OFMSW or MSW; feasible availability matter composting 6783.79 t/year determined.The experiment carried out with segregated at plant, installing piles with-structurants (WE) consisting shavings, sawdust garden waste, no-structurants (NS).Despite unfavorable climatic conditions region, maturity properties similar composts recorded elsewhere, few differences between NS WE.The main limitation concentration heavy metals Cd, Pb Zn, close above limits established several regulations, can be significantly reduced by segregating source.Annual cumulative load 10-year applications, calculated precautionary doses 25 t/ha/year 85 t/ha 10 years dry weight; correcting moisture content, dose 40 wet weight.Depending on available, production dose, 60 80 ha/year agricultural areas forest plantation nurseries could recovered compost; using lower it possible cover larger area.From results, provides valuable information elaborate an integrated management plan, closing cycle production, beneficial use.
