The population of our country is increasing rapidly and due to it plastic waste is also increasing day to day due to urbanization, development activities and changes in life style, which leading extensive environment pollution. Thus disposal of waste plastic is a threat and become a serious problem globally due to their nonbiodegradability and anaesthetic view. Since these are not disposed scie...
Almost a quarter of the plastic produced in Europe still ends up landfills. In addition to loss valuable resources, this leads generation and accumulation microplastics The abundance refuse their spatial distribution landfill body have not been practically studied. current work, changes characteristics from 3 age sections Lap?s regional landfill, Lithuania, depth 10–20 m were A 55 particles/g o...
Microplastics have been found in all hemispheres of the world. However, studies on microplastics are mainly conducted Europe, North America, and East Asia. Few reported Southeast Asian region, where a large number plastic waste is disposed improperly into water. This study investigated abundance characteristics surface water Chao Phraya River (Thailand), Citarum (Indonesia), Saigon (Vietnam). S...
Polybutylene succinate (PBS) has become a potential candidate, similar to polypropylene (PP) and acrylonitrile butadiene styrene (ABS), for use as an organic plastic material due to its outstanding mechanical properties as well as high thermal deformation characteristics. A new composition of silica aerogel nanoparticles extracted from rice waste with PBS is proposed for use as a dielectric (εr...
Plastics are uniquely flexible materials that offer considerable benefits as a simple packing to complex engineering material. Traditional synthetic polymers (often called plastics), such as polypropylene and polyethylene have been derived from non-renewable petrochemicals and known to cause environmental concerns due to their non-biodegradable nature. The enormous use of petroleum-based plasti...
The use of plastic materials such as polypropylene and poly ethylene has faced an enormous increase in the contemporary world. This factor world causes damage to environment. wanted reuse this waste a productive way that reduces ecological occurring One best ways found after numerous researches waste, is utilise them enhancing properties clay soil further using it paving roads. paper focuses on...

Deniaud Garcia Tara Expéditions.) The research vessel Tara, a schooner built for marine and polar research, spent seven months of the last year cruising the Mediterranean Sea on an expedition to collect an unglamorous mater...
Catalytic pyrolysis behavior of synthesized microporous catalysts (conventional Zeolite Socony Mobil–5 (C-ZSM-5), highly uniform nanocrystalline ZSM-5 (HUN-ZSM-5) and β-zeolite), Mesoporous catalysts (highly hydrothermally stable Al-MCM-41 with accessible void defects (Al-MCM-41(hhs)), Kanemite-derived folded silica (KFS-16B) and well-ordered Al-SBA-15 (Al-SBA-15(wo)) were studied with waste po...
