Of the 85 000 hectares of arable land in Mauritius, sugar cane occupies some 85% of that area, the remainder is made up mostly of vegetables and fruit trees. To ensure its economic viability and long term sustanainability, the sugar cane industry through a reform program is striving to add value to its by-products by producing ethanol from molasses and by optimizing energy production from baga ...

Background: For this research Dehydrated Food Waste (DFW), was supplied from Cecconi’s Restaurant, Union House from The University of Melbourne and from the City of Melbourne. The two first places are using the Closed Loop approach for dehydration food waste and the City of Melbourne use the EcoGuardians approach. By dehydration of food waste, is possible to reduce around 85% of weight and 90% ...

Coal ash management would remain a great concern all over the world. Several studies proposed that there is an ample scope for safe utilization of coal ash as a soil ameliorant that may improve physical, chemical and biological properties of the soil and is a source of readily available plant micro and macro nutrient. With this concept a pot culture experiment was carried out in the eastern gh ...

Adding coal ash to acid waste decreases its acidity and supplies essential nutrients to plants. The effects of coal ash on acid coal mine waste and acid mine drainage were investigated in the field. Treatments were mixtures of coal mine waste with coal ash (0, 20, and 40%). Addition of coal ash increased the pH of coal mine waste and leachate by 3.11 and 3.03 units, respectively. After stabili ...

A study, which aims to develop a technology for the preparation of a high quality adsorbent for SOx using coal ash to control air pollution caused by coal-fired thermal power plants in the Philippines, is currently being undertaken jointly by ITDI and HNIRI. During its first year of implementation, the physical, chemical and thermal characteristics of Philippine and Japanese coal ash samples w ...

Industrial waste stocks in Kazakhstan significantly increase and only 10-15 % of total generated industrial waste is utilized. The coal ash and phosphogypsum usage as soil fertilizers is appropriate, however, there is a need for additional investigation of ecological risks related with this industrial waste utilization technology. The aim of this research is to investigate the effect of phosph ...

In the Philippines, the government has started to impose environmental regulations to keep its environment free from hazardous and toxic elements. Among the detrimental pollutants being looked into, the government is focusing its attention to the hazardous emissions from coal-fired thermal power plants, in particular, to the reduction of SO sub x emissions. ITDIA had developed a process for th ...

The effects of soil pollution with coal ash on the number and enzymatic activity of soil microorganisms were investigated. Soil samples were treated with three different rates of ash and two rates of nitrogen fertilization. Coal fly ash pollution resulted in increase of soil fungi and cellulolytic microorganisms and the simultaneous decrease of Azotobacter spp. Coal ash enhances the urease act ...

A drenagem ácida é um problema ambiental, não-exclusivo, mas comumente associado à mineração do carvão e decorrente da oxidação de sulfetos, como a pirita, presente nos estéreis e rejeitos da mineração. A cinza derivada da queima do carvão constitui um resíduo, de utilização ainda limitada, no Brasil, mas que apresenta potencial de neutralização da acidez. Desse modo, estudou-se a possibilidad ...
