Compost application to agricultural land needs to ensure sustainable development. Hence it is important to determine the fertilizer value and soil conditioning ability of composts, and further to assess the risk of adverse environmental effects, such as excessive nitrate leaching. A lysimeter study was undertaken on poor quality sand to …

The paper is concerned with the anaerobic co-digestion of wastewater treatment plant sludge and organic waste coming from the fresh food department of a large market store where a source separated collection system is installed. In particular the study is aimed to verify – by means of pilot plant operation …

There are very few construction and demolition (C&D) waste recycling centres in Brazil. Data relating to C&D waste management and recycling in Brazil were collected and analysed to encourage the building and operation of new units. Based on the results of this analysis, a conceptual model was proposed to perform …

Drainage and liquid collection systems are components of fundamental importance in landfills and waste disposal areas. Sand, gravels and geosynthetics are materials commonly used as filters and draining media in landfill drainage systems. However, the waste itself contains elements that could be employed as drainage material. This paper presents an …

Almost 60% of waste disposal sites in Brazil are open dumps with no infrastructure for environmental protection. It is usual to find uncovered waste. The rainwater runs off over the uncovered top of the waste dump. This water may contaminate the soil. This paper discusses the contamination values in the …

The objective of the present work is to present a physical characterization of the polymeric wastes conducted in the conventional collection of the municipality of São Carlos, SP. The method adopted for physical characterization was by sampling, where the number of samples involved all of the sections, with the weight …
