The content, behaviour and significance of heavy metals in composted waste materials is important from two potentially conflicting aspects of environmental legislation in terms of: (a) defining end-of-waste criteria and increasing recycling of composted residuals on land and (b) protecting soil quality by preventing contamination. This review examines the effects of heavy metals in compost and ...

This experiment was performed to investigate the effect of Azolla and rice straw mixed compost in peat substitution on Dieffenbachia amoena. Factorial experiment based on a completely randomized design with two factors of nutrient solution in 2 levels (1- without solution, 2- with 130 mg N/ l, 32 mg P /l and 117 mg K/ l) and 5 levels of Azolla and rice straw mixed compost (zero, 15, 30, 45 and ...

INTRODUCTION An environmental impact assessment (EIA) before embarking on any project is a useful tool to reduce the potential effects of each project, including landfill, if possible. The main objective of this study was to assess the environmental impact of the current municipal solid waste disposal site of Gonabad by using the Iranian Leopold matrix method. METHODS This cross-sectional stu...

composting of waste plant materials and its use in agriculture and landscape sites is an environmental friendly way of reducing waste material and conserving the environment. in this perspectives a survey has been performed at the dubai based international center for biosaline agriculture to compost the plants based waste material (lawn cuttings-grass) to compost. the material was inoculated wi...
