Silkworms (Tubifex sp) are a natural feed with high nutritional content and needed by fish, especially in the fry phase to support fish growth. Therefore, knowledge of food cultivation is success farming. Silkworm requires media organic content. Tofu pulp waste one that can be utilized for silkworm cultivation. The purpose this activity increase community skills utilizing tofu as medium provide...

background and objectives: hospitals usually generate large amounts of hazardous waste. if not managed properly, hospital waste can pose threats to public safety and damage the environment. waste minimization is a waste management approach that focuses on reducing the amount and toxicity of hazardous wastes. this study pursues a two-fold purpose: 1) to gain insight into hospital waste minimizat...

The world demands more and energy due to the continuous population increase. In parallel, high organic nutrient contents of wastewater streams are generated from anthropogenic activities like urbanization, industrialization, agricultural practices. discharge these into water bodies has been considered responsible for oxygen depletion eutrophication in environment. Integrating microalgae cultiva...

Management of municipal solid waste (MSW) has become a significant environmental problem, especially in fast-growing cities. The amount of waste generated increases each year and this makes it difficult to create solutions which due to the increase in waste generation year after year and having to identify a solution that will have minimum impact on the environment. To determine the most sustai...

Megacities concentrate large amounts of people, absorb a large quantity of resources and generate vast amounts of waste and sewage, thereby contributing considerably to the use of the environment as a sink. The quantity of resources consumed and urban residues produced per capita tend to rise steadily with increased per capita income. Proper management of municipal solid waste is critical to th...

BACKGROUND Medical establishment such as hospitals and research institutes generate sizable amount of hazardous waste. Health care workers, patients are at risk of acquiring infection from sharps and contamination of environment with multiple drug resistant microorganisms if wastes are not properly managed. OBJECTIVES To characterize types and evaluate waste disposal techniques employed in th...
