Process for converting waste, effluents and organic by-products in recyclable materials

A group of researchers from a Portuguese university has developed a biological process to treat waste, effluents and organic by-products with industrial origin characterized by high biodegradability that adds value to conventional biological treatment processes, integrating their assumptions on the concept of biorefinery. The invention aims to reduce by 96% the organic matter content of the starting substrate allowing generally meet the discharge criteria set out in the legislation.

Low Cost Minimum Quantity of Lubricant System

A group of researchers from a Portuguese university has developed a system of "Minimal Quantity of Lubricants" fully functional and automated. The term MQL, "Minimal Quantity of Lubricant", refers to the use of a low lubricant flow (10 to 100 mL / hr) through a high pressure fluid (compressed air). This system is an alternative to most lubrication systems used in machining operations, with both economically and ecological level advantages, contributing to sustainable manufacturing ...
