Construction solid waste has caused serious environmental problems. Reuse, recycling and reduction of construction materials have been advocated for many years, and various methods have been investigated. However, the effectiveness of its applications seems limited. This paper examines rates of reusable and recyclable waste for six major types of building materials: plastic, paper, timber, meta...

This paper deals with the status of solid waste pollution in touristic spots of North coastal Andhra Pradesh. Case studies of Eco tourism, cultural tourism and pilgrim tourism are elaborately discussed and the study is based on both primary and secondary data. Data collection includes field collection of solid waste, semi structured interviews and observation of tourists. Results indicate gener...

The degree of meat adhesion to different kinds of plastic casings was examined in retort sterilized fish sausages. It was found that the plastic casings of great wettability such as polyvinylidene chloride, polyvinylidene fluoride, polyester and polyamide brought about greater meat adhesion than the ones of low wettability such as polyethylene and polypropylene. If polyethylene casing was modif...

Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health. Implementing mitigation strategies requires an understanding and quantification of marine plastic sources, taking spatial and temporal variability into account. Here we present a global model of plastic inputs from rivers into ...

In this study, the Taguchi method is used to find the optimal process parameters for an injection moulding machine that was used to produce a consumer product (plastic tray) from polypropylene (PP) plastic material. An orthogonal array (OA), main effect, signal-to-noise (S/N) ratio, and analysis of variance (ANOVA) were employed to investigate the bending characteristics of the tray under a con...

Separating different components of a plastic mixture is crucial in its recycling. Among the separation techniques, flotation was selected as cheap, non-toxic, and efficient process. Basis technique refers to selective adsorption depressant on plastics surface which cause alteration energy plastic. Adsorption lignosulfonic acid sodium salt (SL) available waste stream studied. Plastics used this ...

The Disposal of large quantity of plastic cover may cause pollution of land, water bodies and air. The proposed concrete which is made up by adding plastic in concrete may help to reuse the plastic cover as one of the constituents material of concrete, to improve the certain properties of concrete. The properties of concrete as varying percentages of plastic will test for compressive strength a...

In 2014, 94 paired neuston net samples (0.5 mm mesh) were collected from the surface waters of Lake Superior. These comprise most comprehensive water survey for microplastics any Great Lakes to date, and first employ double trawls. Microplastic abundance estimates showed wide variability, ranging between 4000 more than 100,000 particles/km2 with locations having abundances 20,000 50,000 particl...

An emerging problem in marine environment is represented by the plastic presence in the water column (THOMPSON et al., 2004) and the risk of their input and accumulation in the trophic web (TEUTEN et al., 2009; GALGANI et al., 2013a). Plastics are worldwide distributed, from surface to deep waters, include particles less than 20 mm of several polymers such as polyester, nylon, polyethylene, pol...

Plastic materials are defined as including the whole of organic polymers owning plasticity. Their production increases rapidly due to their superior properties and applications in our life. Currently, annual plastic is estimated at nearly 400 million tons. About 10% produced discharged into seas oceans. Microplastics (MP, less than 5 mm size) non-biodegradable persistent environment have abilit...
