Little is known about the comprehensive factors influencing temporal changes in microplastic abundance marine ecosystems. We investigated seasonal variations distribution sediments multiple-used zones of Eastern Guangdong South China Sea. The top 10 cm from 26 sites were collected by grab sampling spring, summer, and winter 2021. Marine had lowest significantly lower than other seasons. size mi...

Regulations have been adopted in several countries of the European Union which prescribe that dental treatment waste water must be discharged via an amalgam separator device. Since the effectivity of the device strongly depends on the size of the amalgam waste particles, this size was evaluated in waste water samples from eight dental offices. Per sample, all solid particles were separated from...

Currently, plastic waste is a very serious threat because pollution can harm all living things around and also the environment. The increasing volume of due to lack processing technology, so that day by day. Plastic material difficult decompose it non-biodegradable. One application technology offered in this study use pyrolysis principle. Pyrolysis method converting into fuel oil through therma...

Plastics can be grouped into two groups, thermoplast plastics and thermoset plastics. Thermoplast plastic is a that molded over again in the presence of heat. include PE (Polyethylene), PP (Polypropylene), PS (Polystyrene), ABS (Abutile Butadine Styrene), Nylon, PET (Polyethylene Terephthalete), POM (Polyacetal), PC (Polycarbonate), etc. At process making vases presented this work, material use...

Propylene is one type of plastic that is widely used in our everyday life. This study focuses on the identification and justification of the optimum process parameters for polypropylene production in a novel pilot plant based fluidized bed reactor. This first-of-its-kind statistical modeling with experimental validation for the process parameters of polypropylene production was conducted by app...

The drawbacks are that the concrete has been improved by using hybrid fibre in concrete. By hybridization benefits from two different fibres utilized a single mixture. hybrids studied basalt-polypropylene fibre, polypropylene-steel steel-coconut polypropylene-e-waste polypropylene-polyvinyl Alcohol and steel-glass- polypropylene fibre. properties compressive strength, tensile flexural limited c...

By sampling with neuston nets, Carpenter and Smith (1972) demonstrated the presence, in 1971, of small particles of plastic on the surface of the Sargasso Sea. The particles had an average concentration of 3500 pieces/km’ and occurred over a distance of 1300 km. The occurrence, reported here, of similar particles in the stomachs of Leach’ s Petrels (Oceanodroma ZeucoAoa) indicates that this for...

Adiox is a state-of-the-art dioxin removal technology that has established itself as a cost-effective way to reduce dioxin emissions to the atmosphere. Adiox is a construction material in which carbon particles are dispersed in a polymer such as polypropylene. Several types of components such as tower packings for wet scrubbers, demisters (droplet separators) and dry or semi-wet fixed bed filli...

The separation of one or a group plastics from mix by flotation technique is an essential topic in plastic waste management. Basis the refers to selective adsorption depressant on surface plastic. Consequently, energy alters. Adsorption lignosulfonic acid sodium salt (SL) selected available stream was studied at different SL concentrations and operative temperatures. Studied were Polyvinylchlor...

Plastics, one of the most abundant materials in the world today, are one of the main sources of pollution. People’s perception of using and disposing plastic bags is primordial as they tend to be a major part of household solid waste. This study aims to determine community’s perception of usage and disposal of plastic bags in Eastern Ethiopia. A quantitative cross-sectional study has been condu...
