Plastic wastes (PW) create chronic environmental problems mainly because it is not biodegradable. The utilization of PW as a fractional substitution fine aggregate in concrete production sustainable application. However, the smooth surface plastic weakens cement-plastic bond and consequently lessens mechanical properties concrete. This research improves by increasing hydrophilicity coarseness p...

This paper describes the Syrian experience with respect to Naturally Occurring Radioactive Materials (NORM) waste produced by the Syrian oil industry. Three main categories of NORM waste were identified. First, hard scales from decontamination of contaminated equipment and tubular that are considered to contain the highest levels of radium isotopes (Ra, Ra, Ra); this type of waste being current...

Events like trade fairs are a complex service activity with a considerable economic, social and environmental impact due, among other factors, to their high level of waste generation. There are few studies of the environmental impact associated with waste generation and typology. An environmental analysis methodology has been developed to characterise the waste associated with the temporary str...

The efficient large-scale recycling of plastic waste is of increasing interest from an ecological and economic point of view but it represents a goal that has yet to be achieved by the recycling industry. European project W2Plastics (FP7) aims at a fundamental change of the present status of plastics recycling by applying the Magnetic Density Separation (MDS) technology as well as the Ultrasoun...

The production of activated carbons (ACs) from dirty plastic wastes derived the mechanical/biological treatment urban solid wastes, disposable plastics and used in agriculture is reported. use these precursors innovative contributes to circular economy by valorization that are usually disposed landfills. ACs were produced physical activation, with air or CO2, chemical KOH K2CO3. presented a BET...

The environmental indicators and the classification of beach waste are essential tools to diagnose the current situation and to indicate ways to improve the quality of this environment. The purpose of this paper was to perform a quali-quantitative analysis of the beach waste on the Curva da Jurema Beach (Espírito Santo Brazil). Three transects were used with equidistant positioning over the tot...

Vermicomposts processed commercially from food wastes and paper wastes were applied, to 4.5 m(2) field plots, under high plastic hoop tunnels, at rates of 5 or 10 tha(-1) to evaluate their effects on the growth and yields of strawberries (Fragaria ananasa) var. 'Chandler'. The vermicomposts were incorporated into the top 10 cm of soil and supplemented, based on chemical analyses, with amounts o...

A Publication of the Association for Iron & Steel Technology Ironand steelmaking processes present a largely untapped opportunity to transform some of the world’s most problematic waste streams into raw materials for production. This opportunity lies in their high-temperature environments, which offer sustainable pathways for utilizing chemical reactions to repurpose waste materials as resource...

Port Harcourt is known in local parlance as the ‘Garden City’ of Rivers State. This so tagged because overwhelming presence trees (Green Life) and flowers Metropolis. But today, it different streets, gutters, rivers environs are littered with all types plastic waste (MSW). These municipal solid wastes (MSW), indiscriminately dumped at locations Garden City. Plastics constitute a major component...
