The operating conditions in spouted bed regime of uniform beds consisting of different biomass wastes dry and wet have been studied to determine the applicability of conical spouted beds with a draft tube in the drying of biomass wastes. This experimental study has been carried out at room temperature and the effect of the solid humidity on the stability of beds of biomass wastes has been deter...

PT. XYZ is a company that produces pharmaceutical products for livestock. Most of the raw materials veterinary drugs consist B3 powder (toxic and hazardous materials). Waste from production process unavoidable, one types waste produced by wastes. According to Environmental Service (DLH) cannot be directly discharged into environment, therefore uses 3rd party services in processing disposal. pow...

In several countries, low-level radioactive wastes are treated and stored awaiting construction and operation of a final repository. In some cases, interim storage may be extended for decades requiring special attention regarding security issues. The International Atomic Energy Agency (IAEA) recommends segregation of wastes that may be exempted from interim storage or ultimate disposal. The pap...

This study was carried out to reveal the plastic wastes separation practice and disposal mechanism as well as awareness of the negative impact of plastic wastes on the environment, in Makurdi area of Benue State, Nigeria. Questionnaires were administered to 468 individual respondents in 6 sub-locations of the city. Inquisition was also made from 10 hospitals, 6 market centers and the waste mana...

Management of municipal solid wastes (MSW) in most developed societies now involves the use of thermo-chemical conversion methods. This leads to energy and material recovery while also protecting the environment. However, till date most of the wastes generated in Nigeria (including plastic wastes) are either land-filled or openly burnt. These methods are not sustainable and environmentally non-...

after the boom of pharmacological research during the 1950s, mainly as a result of the screening technique, the identification of active molecules, their reshaping by means of pharmaco-chemical drug design, and the creation of extremely efficacious and successful medicines, the pharmaceutical world sought a new source of inspiration. such biota as the tropical forest, a quantity of plants credi...

Activated carbon is a carbonaceous material with highly porous structure. Different functionalities can be introduced to its surface by various physical and chemical treatments. Various precursors used for the synthesis of activated such as fossil fuels, agricultural wastes, lignocellulosic etc. Number papers have been reported in literature devoted synthesis, characterization, applications car...

the purpose of this research was to evaluate the recovery potential of solid waste in mashhad. the solid waste generated in the regions 4, 5 and 6 has been quantified and characterized using direct weighing, physical testing and truckload sampling methods. to determine the quantity and quality of waste generated and its seasonal variations, chemical and physical analysis were carried out for on...

The management of the 86,388.00 tons of solid wastes generated every day in Mexico is a complicated matter. In order to help solve this problem, sustainable buildings that include solid waste management plants and community awareness programs are being constructed. The objective of this research is to propose the building of a reception and storage center for storing the economically valuable w...
