TL;DR: The results introduce an asphalt mix that has properties that makes it suitable for practical use and furthermore, the recycling of PET for asphalt concrete roads helps alleviate an environmental problem and saves energy.

TL;DR: It has been concluded that the splitting of LPI into three sub-indices provides a better insight on the strength of various pollutants and can be useful to the experts in deciding various management issues regarding leachate treatment.

TL;DR: Analysis of informal refuse collection in three Mexican cities argues that it can supplement municipal collection, create jobs, benefit the economy and help clean up the urban environment.

TL;DR: The compost produced by day 9 showed no inhibitory effect on the growth of Komatsuna, indicating that the maturity of compost is sufficient for plant growth when the rate of organic matter decomposition has become extremely low and the RFLP patterns become stable.

TL;DR: This study provides the first comprehensive review and analysis focused on primary and secondary valuation studies, conducted since 1990, and reveals inconsistency in part of the estimates across the reviewed studies and provides reasonable explanations for the variations.

TL;DR: The results in this study show that in order to improve long-term prediction of the leachate quality and quantity the magnitude of the preferential water flow through a landfill must be taken into account.

TL;DR: Composting studies during a 45-day experiment showed that the percentage elongation (reduction) was 20% for McD samples and LL samples and 18% reduction for totally degradable plastic (TDP) samples (HDPE with 3% additive).

TL;DR: The aesthetic and chemical characterization of the tiles glazed by this product showed an extremely similar behaviour to originals that did not contain CRT glass, supported by the life cycle assessment analysis, which has demonstrated a reduction of the environmental impact of theCRT glass-containing ceramic glaze with respect to the standard one.

TL;DR: Concerns about increased sludge generation persist and its potential environmental and economic implications may differ with location and therefore area-specific characteristics must be taken into consideration when contemplating the adoption of a strategy to integrate food waste disposers in the waste–wastewater management system.

TL;DR: Statistical analysis indicates that waste characteristics are different among geographical regions and seasons.

TL;DR: These guidelines have been used to assess a major London hospital and highlighted a number of deficiencies in current practice, including a lack of control over purchasing and supply, and very low rates of segregation of municipal solid waste from hazardous health-care waste.

TL;DR: A case study on solid waste collection and recycling practices in Nibong Tebal town, Penang, Malaysia and the majority of the respondents expressed concerns about recycling and wanted more to be done in this regard.

TL;DR: The results of model calculations carried out to identify and quantify the input pathways of trace elements into cement and concrete and to estimate the extent to which trace element concentrations in cement may change due to waste utilization are presented are presented.

TL;DR: An anthropological perspective on garbage explores the fact that what constitutes waste is a highly subjective notion, and how perceptions of waste are important parts of local waste management systems and the understanding of such perceptions might increase the effectiveness of waste management campaigns.

TL;DR: In order to achieve very low N2O emissions from waste incineration, particularly for waste with higher nitrogen content (e.g. sewage sludge), two factors are important: temperature of incineration over 900°C and avoiding the selective non-catalytic reduction (SNCR) de-NOX method based on urea or ammonia treatments.

TL;DR: To reduce chloride content in MSW bottom ash, a laboratory investigation was carried out based on the exhaustive washing in tap water, and preliminary indications on mechanistic aspects of the washing operation are given.

TL;DR: An assessment of fugitive pollutant emissions and a dispersion analysis down-wind of a specific landfill site and the assessed air pollutant concentration for several air pollutants was significantly above the World Health Organization reference lifetime exposure health criteria.

TL;DR: A process for nickel recovery from a spent catalyst of definite composition using the hydro-metallurgical route and nickel was recovered as value-added products such as sulphide and oxalate with overall recovery of 90 and 88% of nickel, respectively.

TL;DR: A high proportion of incorrectly segregated medical waste was found at each level of health-care facility level, and a higher proportion of medical waste from the inpatient department at the primary health- Care level was found.

TL;DR: The results of the quiescent settling experiment showed that the settling type could be termed flocculent settling, and it was found that waste sludge up to 9% could effectively be used as an additive material in cement.

TL;DR: Comparative evaluation of bioenergy production from food waste was carried out with both a temperature-phasing and a conventional mesophilic two-phased process at different organic loading rates (OLRs), with significant amount of methane content detected.

TL;DR: Micrometeorological measurements of methane (CH4) and nitrous oxide (N2O) emissions were made at the decommissioned Park Road Landfill in Grimsby, Ontario, Canada between June and August 2002 to assess the influence of precipitation, air temperature, wind speed and barometric pressure on the temporal variability of landfill biogas emissions.

TL;DR: The concentration of Zn, Cu, Pb, Cr, Ni, Cd, As and Hg in combustible waste (wet as received) at 14 Danish incinerators, representing about 80% of the waste incinerated in Denmark, showed the highest concentration.

TL;DR: The uncertainty about European waste generation and treatment capacity, however, might have a large influence on the future gate fees and thus also on the yellow waste import into Sweden.

TL;DR: A life-cycle assessment (LCA) of sewage sludge SCWO (Aqua-Critox) is presented and the results are compared with LCA results for other sludge handling options: agricultural use, co-incineration with municipal solid waste, incineration with subsequent phosphorus extraction (Bio-Con), and sludge fractionation with phosphorus recovery (Cambi-KREPRO).

TL;DR: According to the test results, waste sludge generated in the paper industry may be considered to be chemically and microbiologically stable as there was practically no emission of odorous and toxic compounds such as H2S, NH3 and butyric acid despite prolonged storage times and elevated environmental temperatures.

TL;DR: Computational results of bin location, type, size and the frequency of removal are presented for a typical urban area with known population density, income group distribution, road network and topology.

TL;DR: There was some evidence to support a theoretical risk of infection with hepatitis A, B and tetanus; however, no studies could be found of the risk of these diseases in solid waste workers and workers in the solid waste industry may theoretically be at increased risk of acquiring infectious diseases occupationally.

TL;DR: The low contents of heavy metals in the raw materials used in the bioconversions ensured the safety of fertilizer from food waste for application in agriculture and increased the stability of the final product.

TL;DR: The analysis indicated that the lifespan of all new goods is gradually reducing and provided linearized functions for predicting the lifespan, according to the year of manufacture, for certain large appliances.
