| One of the most ubiquitous and long-lasting recent changes to the surface of our planet is the accumulation and fragmentation of plastics. Within just a few decades since mass production of plastic products commenced in the 1950s, plastic debris has accumulated in terrestrial environments, in the open ocean, on shorelines of even the most remote islands and in the deep sea. Annual clean-up operations, costing millions of pounds sterling, are now organized in many countries and on every continent. Here we document global plastics production and the accumulation of plastic waste. While plastics typically constitute approximately 10 per cent of discarded waste, they represent a much greater proportion of the debris accumulating on shorelines. Mega- and... |

| The microbial populations of groundwaters were analyzed in a region under the influence of a landfill (piezometer L12) in the town of São Carlos, São Paulo, Brazil, and in an area not influenced by the landfill (piezometer L5). Heterotrophic bacteria were counted by spread plate method and the number of protozoa was estimated by the most probable number method. There was a larger number of organisms in well L12, with a mean value of 15.76 x 104 CFU/ml for bacteria and 9.7 MPN/ml for protozoa, whereas the mean values for piezometer L5 were 2.88 x 104 CFU/ml for bacteria and 3.4 MPN/ml for protozoa. The greater abundance detected in piezometer L12 may be related to the influence of the leachate through the landfill on the microbial populations, also... |

| The environmental impact of locating two polluting sources of landfill (refuse dump) and petrochemicals on Alaba stream in Akure, Nigeria was assessed. This was due to the dependence of Alaba inhabitants and its environment on the stream for variety of uses. Twenty physio-chemical parameters were analyzed for wet and dry seasons respectively with three sampling points within 5m intervals from one another of the two polluting sources on the stream. The parameters included: colour, odour, taste, pH, temperature, turbidity, alkalinity, conductivity, dissolved oxygen (DO), biochemical oxygen demand (BOD5) and total solids (TS). Others were chloride (CL-), total dissolved solids (TDS), total suspended solids (TSS), lead (Pb), nitrate (NO3), sulphate (SO4-2),... |

| A strain of Gordonia sp. (strain Lc), from landfill leachate-contaminated groundwater was characterized by polyphasic taxonomy and studied for exopolysaccharide (EPS) production. The cells were Gram-positive, catalase-positive, oxidase-negative and non-motile. The organism grew both aerobically and, in anoxic environment, in the presence of NaNO3. Rods occured singly, in pairs or in a typical coryneform V-shaped. The organism had morphological, physiological and chemical properties consistent with its assignment to the genus Gordonia and mycolic and fatty acid pattern that corresponded to those of G. polyisoprenivorans DSM 44302T. The comparison of the sequence of the first 500 bases of the 16S rDNA of strain Lc gave 100% similarity with the type strain of... |

| In Latin Americ a, the most accepted disposal systems for Municipal Solid Waste (MSW) are landfills, which nowadays have low rates of stabilization. The objective of this study was to develop design criteria for sanitary landfills which lead to a reduction in the stabilization times of MSW, based on experiment results obtain from a pre-pilot scale operation of two sanitary landfills (0.5 Ton), one with recirculation of leachates treated in an anaerobic digester and the other with recirculation of untreated leachates. This was complemented by another pilot scale sanitary landfill (1440 Ton) with recirculation of leaches treated in an anaerobic filter, and additionally by a computer simulation of leachate generation through the water balance of a theoretical... |

| The Japanese government has encouraged reduction, reuse, and recycling of waste with the slogan "3R" under the Basic Law for Establishing a Recycling-based Society. However, the law is non-binding in nature; thus, the collection of each type of recyclable containers and packaging is done at the discretion of the municipalities. Some municipalities do not provide collection services for these recyclables. Why do some municipalities recycle while others do not? Few studies have investigated the determinants of the municipality's decision to collect recyclables. The purpose of this study is to examine the factors affecting a municipality's decision to implement the collection of already sorted recyclable containers and packaging in Japan. We use a panel data... |
