Kuhlman, L.R., 1990. Window composting of agricultural and municipal wastes. Eur. Symp. on Integrated Resource Recovery from Municipal Solid Wastes. Resour. Conserv. Recycl., 4: 1 5 1 160. Many wastes are produced from agricultural and municipal facilities that are not suitable for direct land application. Composting these wastes converts them to a humus-containing organic material advantageous...

Sludge dewatering and treatment may cost as much as the wastewater treatment. Usually large proportion of the pollutants in wastewater is organic. They are attacked by saprophytic microorganisms, i.e. organisms that feed upon dead organic matter. Activity of organisms causes decomposition of organic matter and destroys them, where the bacteria convert the organic matter or other constituents in...

Wastes generated from the production of cattle and swine in confined facilities create the potential for surface and groundwater pollution, emission of greenhouse gases, transmission of pathogens to food and water sources, and odor. It is our hypothesis that something which inhibits microbial fermentation in livestock wastes will be beneficial to solving some of the environmental problems. Our ...

This paper presents a comparison of dry anaerobic digestion reactors fed with differently sorted municipal organic solid wastes. One reactor was fed with source sorted organic wastes and a second reactor was fed with mixed organic wastes consisting of grey wastes, mechanically selected municipal solid wastes and sludge. The two reactors utilised the same process (Valorga) and operational condit...

The edible mushroom Pleurotus ostreatus has been studied as a potential crop to reduce agricultural solid wastes and increase mushroom production. P. ostreatus cultivated on various agricultural wastes singly i.e. rice straw (RS), rice husk (RH) wheat straw (WH), barley straw (BS), and cotton wastes (CW). The biological efficiency (B.E) was 25.61, 9.51, 22.6, 21.628 and 25.78 % while rounding u...

Every industrial unit generates wastes along with the processed goods. These wastes actually represent loss of the valuable material and energy from the production processes and investment in the pollution control. Usual approach followed by the industries, to cope with the problem of wastes and pollution, is use of waste treatment systems as end-of-pipe remedies. The remedies adopted often res...

Fig. 1. Relationship between waste and raw materials in the production and use of building materials; the lines illustrating areas of interest for Waste Management are emphasized. An ever-increasing number of papers focusing on the use of waste as an alternative material in the production of building materials is being submitted to Waste Management. Indeed, the wide variety of waste components ...

Currently, much of our biodegradable wastes such as kitchen wastes, agricultural wastes & animal wastes are used to produce Biogas, a powerful greenhouse gas. Anaerobic digestion (AD) is a treatment that composts these wastes in the absence of oxygen, producing a biogas that can be used to generate Heat & Power. Producing renewable energy from our biodegradable wastes helps to tackle the energy...

The disposal of clinical wastes is often poorly conducted and inadequately supervised despite the publication of clear and definitive working guidelines and the introduction of increasingly stringent legislative control. The move away from landfill disposal of clinical wastes, and the further development of high temperature incinerators able to meet increasingly tight emission limits, is to be ...
