The disposal of industri al eftluents is a problem of increasing importance throughout the world. In Indi a, a huge amount of waste water generated from distillery and paper industri es is discharged on land or into the running water. Di stillery waste water is characterized by low pH, hi gh BOD and COD values and contains a high percentage of organic and inorganic material s. This waste water ...

This synopsis of FT-IR spectroscopic applications in waste management covers relevant issues regarding monitoring, process and quality control. Quality in this context means low reactivity, low gas forming potential and compliance with limit values of materials to be landfilled, appropriate compost ingredients and improvement of the stable carbon pool by humification of compost organic matter. ...

Organic matter transformation using chemical and spectroscopic methods was studied for composting of four carbon/nitrogen (C/N) ratio waste combinations (C/N 16, C/N 22, C/N 30 and C/N 38) of grass cuttings, mix vegetable waste, cattle manure, food waste and sawdust. Temperature, moisture content, ash content, total organic matter, C/N ratio and water-soluble organic carbon (WSOC) concentration...

This report presents the results of a methane inventory in the solid waste sector of Ukraine. It considers the theoretical background of the methane generation process in solid waste, reviews methodologies used for methane generation assessment, and describes the methane inventory process in a transparent way. This study has been carried out with the purpose of Ukraine's compliance with the req...

Describes field experiments to determine the effects of previous organic waste composts, using different types and application rates, on sunflower yield. Oil, carbohydrates and metal content were evaluated. Experiments were conducted in the Nuclear Research Centre Farm, in sandy, infertile soil. Results show a remarkable increase in dry matter and seed yields, due to previous single compost add...

Background and Objective: Dewatered sewage sludge is a by-product of wastewater treatment process which can cause health and environmental problems if not properly managed. The aim of this study was to determine the feasibility of composting of Yazd WWT dewatered sludge with windrow method using different treatments. Materials and Methods: In this study, the dewatered sewage sludge was mixed...

Anaerobic digestion of dairy cow manure (CM), the organic fraction of municipal solid waste (OFMSW), and cotton gin waste (CGW) was investigated with a two-phase pilot-scale anaerobic digestion (AD) system. The OFMSW and CM were digested as single wastes and as combined wastes. The single waste digestion of CM resulted in 62m3 methane/ton of CM on dry weight basis. The single waste digestion of...

This work describes a simple, rapid, and reliable HPLC method for the determination of organic acids in fermented shrimp waste. Lactic, acetic and citric acids were quantified by HPLC with UV detection, on a 250 ́4.6 mm Extrasil ODS 5-mm column, mobile phase was ultrapure water adjusted with metaphosphoric acid to pH=2.1, flow rate 0.6 mL/min, column temperature 30 °C, and detection wavelength 2...

Introduction Until relatively recently, anaerobic digestion (AD) plants at farm or industry level treated the organic waste arisings from a single farm or from an individual industrial operation. The installation of centralised AD plants, treating animal manures and slurries from a large number of farms, and the increasing use of co-digestion of manures, food-processing wastes, sewage sludge an...

Cellulose is one of the most abundant non-degradable organic compound on earth. Near about half of the municipal and agricultural solid wastes contain cellulose or their derivatives. Saccharification or enzymatic hydrolysis of cellulosic wastes liberates glucose. In the present work, cellulase from Cellulomonas uda was extracted, partially purified by dialysis and immobilized on an organic supp...
