The demand for farm-raised channel catfish (Ictalurus punctatus) has grown tremendously in recent years due to year round availability, consistent quality, and healthy attributes of catfish. In 1993, over 459 million tons of catfish were produced in the United States (Anon., 1994). As this industry has grown, so has the amount of offal, trimmings, and other solid waste generated and the need to...

Considerable attention has been given to chemical methods of reducing the Biochemical Oxygen Demand (B.O.D.) of semi-chemical neutral sulfite waste (S.N.W.). Very little study has been devoted to a biological method. The exact composition of this paper industry waste will vary with the type of wood chip used and the modification of cook. Table 1 shows a typical composition of the liquor resulti...

municipal solid waste. Business and industry operations generate recyclable materials in many areas, such as offices, cafeterias, supply stores, shipping or warehouse units, print shops, and production areas. Many companies are already enthusiastically collecting recyclables in high-profile programs, while others are just beginning. Collecting recyclables costs money, but it also saves money by...

In the food industry, syrups containing a high concentration of sugar used for fruit preservation is abundantly discharged as a food processing waste and disposed by incineration, resulting in the rise of the manufacturing cost and environmental pollution. This study demonstrates how waste syrup can be utilized as carbon source for production of docosahexaenoic acid (DHA) and astaxanthin by the...

With the rapid development of the waste incineration industry in China, top priority has been given to the problem of pollution caused by waste incineration. This study is the first attempt to assess all the waste incineration plants in Wuhan, the only national key city in central China, in terms of environmental impact, site selection, public health and public participation. By using a multi-c...

The waste associated with cleaning of process equipment is probably a significant contr ibutor to the total waste volume generated by industry. This paper addresses the following aspects related to equipment cleaning waste generation: o Review of reasons for cleaning process equipment o Reduction of cleaning frequency o Reduction of quantity and toxicity of cleaning waste o Costs associated wit...

Received: June 06, 2017 Revised: July 05, 2017 Accepted: July 19, 2017 Abstract: Introduction: The use of polymer wastes in pavement as road is an increasing trend in the road construction sector. Those new pavements reduce the amount of solid waste disposed into landfills and provide more sustainable construction due to the use of in-situ materials. Polyurethane foam waste is a thermostable po...

a new, local agro-industrial waste was valorized by chemical treatment and tested for its ability to remove cationic dye from aqueous solution. tendu (diospyros melanoxylon) leaves refuse, a solid waste from bidi industry which caused disposal problem, was studied as a biosorbent. raw tendu waste (tlr), along with sulfuric acid carbonized tendu waste (tlr-cm) and tendu waste treated with dilute...
