Solid Waste Recycling

Most of the cities in the world, a solid waste recycling process is a part of the effective and sustainable waste management system. Although the local authorities ignore the recyclable solid waste materials during waste management activity, a number of self-waste collectors and dealers have been performing recycling activity as a source of acquirement for long periods of time in Bangladesh. In our present study, a traditional recycling practice of solid waste was executed and analyzed in Sadar Upazila of Noakhali, Bangladesh. This study also identified a complete concatenation from waste collectors to recycling industries in different private sectors. The study revealed that 41% metal, 37% paper, 14% tin and 8% plastic of Sonapur was recycled daily. On the other hand, the study also revealed that 44% metal, 21% paper, 19% tin and 16% plastic of Maijdee was recycled daily. The shop owners were only interested with Recyclable Solid Wastes (RSW). RSW collected by the shop owners including glass, paper, plastic, iron, tin etc. All the recyclable materials were collected and transported in different industries of Dhaka. For new products, those retrieved materials were used as raw materials.

Solid Waste Recycling

Abstract Ecofriendly, ecoefficient and sustainable civil engineering work has been research with emphasis on adapting the byproducts of solid waste recycling and reuse to achieving infrastructural activities with low or zero carbon emission. The direction combustion model, the solid waste incinerator caustic soda oxides of carbon entrapment model (SWI-NaOH-OCEM) developed by this research has achieved a zero carbon release. This research adopted the literature search method to put together research results of previous works relevant to the aim of this present work. It has been shown that CO and CO2 emissions can be contained during the derivation of alternative or supplementary cementing materials used in the replacement of ordinary Portland cement in civil engineering works. In the overall assessment of the present review work has left the environment free of the hazards of CO and CO2 emissions. It was shown that these supplementary cementing materials derived from solid wastes improve the engineering properties of treated soft clay and expansive soils, concrete, and asphalt. Bio-peels, another form solid waste has been established as a good detoxificant used in treating wastewater. It has been shown that solid waste recycling and reuse is a hub to achieving ecofriendly, ecoefficient and sustainable infrastructural development on the global scale.

The study was conducted to analyze the solid waste recycling at Sholokbahar Ward of Chittagong City Corporation. Data were collected from primary waste collectors, i.e.Tokai, Feriwala, and Women waste collectors, waste dealers and different recycling plants through questionnaire survey and frequent field visits. The study found that the average amount of collected recyclable solid wastes was 121.37 kg/day in each solid waste recycling shop while waste picker was about 16 kg/day. Interestingly, the amount of average collected solid waste per day by Feriwala was significantly higher than Tokai and women waste pickers. Among of recyclable solid waste about 37% was scrap iron while only 16% was plastic bottle. The study also found that solid waste pickers generally collect wastes on foot while, among Feriwala only 23% use tricycle to collect wastes from door to door. We estimated that, by collecting recyclable solid wastes, each male and female waste picker earn, on an average, Tk. 80 and Tk.53 per day respectively. Finally, this study suggests that both governmental and non-governmental initiatives for solid waste recycling at Sholokbahar area can play a vital role to contribute our national economy, employment opportunities and environmental protection.DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22078 J.
