This study also contributes to reducing environmental pollution caused by plastic and glass waste as well as current construction brick production methods. The results show that the bulk density, compressive strength, and bending strength of brick samples made from PET plastic and glass waste are higher than those of burnt clay brick samples, while water absorption is much smaller than that of burnt clay brick samples.

With the rapid growth of economic development, the circular economy has been raised in many international environmental and socio-economic conferences and forums nowadays. The recycling of plastic waste was one of those aspects. This paper studied the potential of directly reusing plastic bottle caps as bio-carriers in moving bed bioreactors without further waste processing.

We present a method to produce graphene flakes (GFs) from polyethylene terephthalate (PET) bottle wastes by the pyrolysis method using modified bentonite as a catalyst. The as-synthesized GFs are analyzed in terms of crystal phase, morphology, and surface chemistry. The synthesized GFs have a porous, thin, and leaf-like morphology with a length ranging from a few hundred nanometers to a few tens of micrometers.

The increase in solid waste volume and change in composition due to urban development cause negative effects on the marine ecological environment. The aim of this study was to assess the amount of plastic waste leaking into the environment from the municipal solid waste (MSW) management system and propose mitigation measures towards sustainable development in Hue city, Viet Nam.

The recycled steel fibers from waste steel cables have properties suitable for enhancing the load-bearing capacity, impact resistance, and shrinkage reduction of Self-Compacting Concrete (SCC). The use of a high content of fly ash in SCC reduces production costs and is environment friendly by minimizing the amount of cement in the mix. This article presents the experimental research results on the influence of the content of recycled steel fibers on the properties of high-fly-ash SCC.

Wastes generated from healthcare practices are a serious problem for humans as well as for the environment. In this study, an attempt was made to use mixed solid medical waste (WPN) which consisted of shredded waste plastic and chopped waste needles for partial replacement of natural fine aggregate (sand) in concrete mixes at 0%, 2%, 4%, 6%, 8% and 10% by weight.
