Introduction Americans increasingly question decisions of professional risk managers. This trend is most apparent in the areas of nuclear, hazardous chemical and solid waste management. Professionals and the general public strongly disagree about the seriousness of many risks'! The professionals use the expected losses per time unit as the major yardstick to evaluate risks. The public is more c...
Earthworms have been successfully used in the vermistabilization of urban, industrial and agricultural wastes in order to produce organic fertilizers and obtain protein for animal feed. Although many species could be used for these ends, given their nutritional requirements and reproductive biology, only Perionyx excavatus and Lampito mauritii are widely used. The most effective use of earthwor...
Reuse of agricultural wastes and industrial by-products for building materials has been gaining popularity in the recent years. Agricultural waste material; namely rice husk ash (RHA), and industrial by-product; namely expanded polystyrene beads (EPS) are discarded in large amounts globally, causing increased environmental problems. Therefore, this paper introduces innovative efforts of the com...
It is crucial to achieve effective solid waste management involving not only formal/government agencies, but also individual/informal/voluntary actions in order to create a healthy environment. This study conducted to unveil the factors that increase individuals’ community participation in solid waste management policy. The data were matched with a literature review on existing waste policies t...
This paper presents two interval parameter fuzzy programming models for the planning of petroleum solid waste management systems under uncertainty. In these models, fixed violation limits are introduced to relax the critical constraints so that the results produced by these models give more useful information to decision makers. These two models are also applied to a hypothetical planning probl...
Municipal solid waste management (MSWM) is one of the major environmental problems of Indian cities. Improper management of municipal solid waste (MSW) causes hazards to inhabitants. Various studies reveal that about 90% of MSW is disposed of unscientifically in open dumps and landfills, creating problems to public health and the environment. In the present study, an attempt has been made to pr...
Backyard poultry ownership provides a great opportunity for improved self-reliance and small-scale agricultural sustainability through home egg and meat production. One issue with backyard poultry ownership is managing the waste products of your birds, particularly the manure and bedding mixture (termed “litter”) that builds up in the coop. If not managed properly, this waste material can creat...
this study reports the removal of cadmium from wastewater in batch mode, using two carbonaceous adsorbents viz. sunflower head carbon (shc) and sunflower stem carbon (ssc) prepared from waste biomass of sunflower. the adsorbents were characterized by fourier transform infrared spectroscopy (ft-ir), scanning electron microscopy (sem) and energy dispersive x-ray analysis (edx). the results of bat...
Greenhouse gas emissions from the agricultural ecosystem account for 7%–20% of the world’s total greenhouse gas emissions, while approximately 17% of China’s carbon emissions are from agriculture. In this study, based on the scientific calculation system of carbon emissions in agriculture, we calculated the carbon emissions of agriculture in the Hotan prefecture between 1999 and 2013 and analyz...
