Read MoreIncineration of plastic material will cause air pollution, global warming and monsoon failure. Investigations done so far have shown that waste plastics can be utilized for making polymer aggregate blocks with ceramics and granite, which can be used in laying footpaths. The blocks can take 350 tonnes of load and prevents water penetration.
Read Moresand extraction site near Mphephu Resort which is now used as an illegal municipal waste dumping site. The site was previously used as a good grazing land for cattle and other do-mestic animals. Floodplain sand mining has transformed some parts of the study area into large and deep open pits.
Read MoreThe amount of waste per job is dependent on the project requirements including how tight the finished joints are desired to be. Tighter joints require more trimming which generates more waste. A higher waste factor requires more stone to be consumed. For example, lets say you are looking to cover an area that is 100 ft x 10 ft (1,000 SF).
Read MoreHo et al. explained that the granite fines can be used in the SCC production. However, it is important to spot out that, as a waste material, the properties of stone fines are likely to vary with time. Then, after that, the fineness of granite fines could solve durability problems, such as silica-alkali reactions.

Events in the 20th and early in the 21 st century and compendia of waste researches indicate that wastes in whatever form or classification solid, liquid or toxic have become a major sequel of modernisation and economic development [1,2].The global waste generation rates are rising faster than ever, estimated at about 1.3 billion tons/year in that year …
Read MoreTar Sands Extraction. Alberta's Athabasca tar sands lie under about 142,000 square kilometers of land, much of which is locked deep underground, making it hard to extract (CAPP, 2017). Tar sands are known as one of the dirtiest forms of fossil fuel because of the vast economic and environmental costs that are associated with its extraction.
Read MoreBricks made from sand and waste plastic bottle (specimen PB) recorded highest compressive strength of 10.6 MPa. However, normal clay bricks (specimen NB) presented a low compressive strength of 1.77 MPa. It may be noted that bricks made from sand and waste plastics could be used ...
Read MoreSand and cement are indispensable ingredients of concrete but their production is causing sustainability problems. Two strategies have been adopted to reduce their consumption, namely, sand replacement with solid waste and cement replacement with solid waste.
Read MoreArtificial sand, also called crushed sand or mechanical sand (m sand), refers to rocks, mine tailings or industrial waste granules with a particle size of less than 4.75 mm. It is processed by mechanical crushing and sieving. In China, the artificial sand was mainly used in the construction of hydropower systems.
