“…It is suggested that a distance up to 500 m away from water bodies could be acceptable (Kontos et al, 2003). In our study, a buffer distance of 200 m for water bodies is considered unsuitable for allocating OMWW disposal sites (Shabou et al, 2009b), always depending on the pattern of channels and the general hydrology of the first order catchment.…”

Many on-site waste disposal systems fail regularly due to problems concerning suitable location and management. A potential environmental threat is inevitably propagated through on-site, off-site, downstream, soil surface and ground water pollution. Soil is a key component of land suitability for waste disposal. This paper presents a Geographic Information Systems (GIS) – based integrated multicriteria decision support system for evaluating the land suitability for olive mill wastewater (OMWW) disposal in the Mediterranean region. Two-scaled classification schemes are developed, the global scheme for Central and South Greece (scale: 1:30.000) and the local scheme for the study area in Xiromero, Aetolia-Acarnania Prefecture, Western Greece, scale 1:10.000. Constrains and factors are included into the spatial decision-making framework, where geostatistical and fuzzy set theory techniques, as well as Analytical Hierarchy Process (AHP) are appropriately integrated. Physical, chemical, and socioeconomic variables adapted to the Mediterranean soil conditions are incorporated as driving forces for the land suitability assessment and the produced maps reveal valuable results for final end-users, such as municipal authorities, agriculturalists, farmers and other national and local stakeholders.

The previous issue of Waste and Resource Management focussed on some of the outputs of the Engineering and Physical Sciences Research Council's sustainable urban environments programme waste consortium. We will return to that later in the year, but this issue contains a more usual mix of a briefing and four papers covering a number of different topics.The briefing by Jones 1 sets out a timely vision and challenge to the waste management community, to move from the historic view of waste as a problem to an holistic approach integrating economic, technological and sociopolitical aspects and viewing waste as a materials and energy resource on a regional basis.The paper by Harder and Woodard 2 presents the results of a study carried out to assess the potential for 'green cone' food digesters to reduce the amount of household waste set out for kerbside collection and disposal. The key difference between green cone digestion and composting is that the green cone aims to provide an environment in which accelerated aerobic decomposition of biodegradable wastes takes place, rather than to produce compost. Nutrients from the green cone filter naturally into the underlying soil, and the device provides a disposal route for animal and other wastes not normally composted. The study showed a reduction of about 2 kg per household per week in the amount of residual waste set out for kerbside collection, and about 0 . 6 kg per household per week in the amount of non-compostable food materials. In contrast to previous work, the reduction in waste set out for kerbside collection was found to be statistically significant.Fannin et al. 3 describe trials carried out to investigate the effectiveness of a constructed wetland system populated with Spartina and Juncus species for the primary treatment of landfill leachate. The trials demonstrated successful treatment (with ammoniacal nitrogen removal rates of 69-99%) of methanogenic leachate from a municipal solid waste. A commissioning period, during which the ammoniacal nitrogen concentration of the influent to the wetlands was gradually increased from a low value, was required -but this is considered to be small in comparison with the anticipated operational lifespan.The papers by O'Kelly and Quille 4 and by S'Habou et al. 5address different aspects of rather specialised but potentially problematic wastes -residues from municipal water treatment and olive mills respectively. O'Kelly and Quille report the results of a geotechnical investigation into the compressibility and consolidation properties of alum residues from municipal water treatment processes. The quantities of such wastes requiring disposal are increasing, and the paper is set in the context of estimating settlement of the material in lagoons and when used as a fill. It also considers the selection of an appropriate mechanical dewatering system to reduce the water content of the sludge prior to disposal. S'Habou et al. discuss the use of a geographic information system to help with the multi-criteria analysis needed to det...

With regard to environmental facilities, blindness and the subjectivity of site selection lead to serious economic, engineering and social problems. A proper siting proposal often poses a challenge to local governments, as multiple factors should be considered, such as costs, construction conditions and social impact. How to make the optimal siting decision has become a topical issue in academic circles. In order to enrich the framework of site selection models, this study combined GIS, AHP and Remote Sensing (RS) technologies to conduct siting suitability analysis of sewage treatment plants, and it was first applied in the Liao River basin in Jilin Province in China. The enriched model is able to reveal blindness in the former site selection of sewage treatment plants and explore optimal siting areas, involving an effective quantification method for summer dominant wind direction and urban stream direction. In a case study, it was found that local governments need to be cautious of the distance of sites from rivers and residential areas and the impact of these sites on downwind and downstream residents. Additionally, siting suitability has obvious regional characteristics, and its distribution varies significantly between towns. Huaide Town shows the largest optimal siting areas and can be given priority for the construction of new sewage treatment plants. This paper developed a more scientific approach to site selection, and the outcome can provide a robust reference for local governments.
