After completing the thio-substitution with Lawesson’s reagent, ethanol was found to be effective in decomposition of inherent stoichiometric six-membered-ring byproduct from reagent a highly polarized diethyl thiophosphonate. The treatment significantly simplified following chromatography purification desired thioamide small scale preparation. As scaling up preparation two pincer-type thioamid...

In physician's offices and biomedical labs, biological waste is handled every day. This waste is disposed of in waste containers designed for holding red autoclave bags. The containers used in these environments are closed hands-free containers, often with a step pedal. While these containers protect the user from surface-borne microorganisms, the containers may allow airborne microorganisms to...

E-waste or electronic waste is a major waste stream resulting from the boom in consumer electronics in the past decades. With the rapid pace of technology innovation and obsolescence that leads to shortened product lifespans, the growing demand for electronics and its resulting waste poses a significant challenge in every stage of its life-cycle from the utilization of raw materials, production...

Grounding Waste: Towards a Sociology of Waste Networks. This article contributes towards building a sociology of waste. It advances a network analysis framework to understand the position and role of the various actors involved in waste governance in Ireland, North and South. It is the state at the EU and national levels that has sought to deal with waste within the competing sustainability and...

BACKGROUND Waste produced in dental clinics has been the topic of investigations for many years. These waste materials have important health impacts and are hazardous to humans and the environment. OBJECTIVE To investigating solid waste production and its management in dental clinics in Gorgan, northern Iran. METHODS In this cross-sectional study, 45 of 143 public dental practices and 5 of ...

By-product and waste streams from the food industry could be regarded as ideal renewable feedstocks for the production of value-added products. The utilisation of food processing wastes could lead to the development of a sustainable chemical industry and a food industry that will cause less environmental concerns. This will be achieved via simultaneous substitution of fossil raw materials and r...

erythromycin production is clearly enhanced by the addition of vegetable oils. however,whether this positive effect is brought about by the triglyceride or non-triglyceride fraction, isnot clear. the non-triglyceride portions of the oils accumulate in the waste during the refiningprocess leaving mainly triglycerides in the refined oil. in this research, sub-fractions of soybeanoil, including le...

Biodiesel is usually produced from food-grade vegetable oils that are more expensive than diesel fuel. Therefore, biodiesel produced from food-grade vegetable oil is currently not economically feasible. Waste cooking oils, restaurant grease and animal fats are potential feedstocks for biodiesel. These inexpensive feedstocks represent one-third of the US total fats and oil production, but are cu...
