What we mean by a circular economy?

A circular economy is one that keeps materials in use, at their highest value, for as long as
possible. It does so through products designed to be long lasting, easy to repair and recycle, and through systems that capture those products when they are no longer
wanted, either to sell them on to another user or recover their materials for another use.
Reuse is the most economically and environmentally beneficial strategy within a
circular economy. Finished products are worth much more than the raw materials they
are composed of and direct reuse preserves the most value and embodied energy. For
example, a reused iPhone retains around 48 per cent of its original value after two years,
whereas the value of the materials you can recover from it is just 0.24 per cent of its
original value. Continue reading What we mean by a circular economy?

What is pH?

The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH of less than 7 is acidic, and a pH greater than 7 is basic. Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value. For example, a pH of 10 is ten times more alkaline than a pH of 9. Pure water is neutral, with a pH of 7.0.

The pH scale shows the acid or alakine level of various common materials.

Project Profile on Bleached Cotton Linters (BCL)

There exists a huge demand for Bleached Cotton Linters (BCL) in the defense sector for manufacturing Nitrocellulose used in explosives and propellants. For manufacturing 1000 MT of Bleached Cotton Linters, approximately 1500 MT of Raw Cotton Linters (RCL) is required. Sometimes BCL producers face an acute shortage of their basic raw material i.e. good quality Raw Cotton Linters. This happens when Raw Cotton Linter manufacturers resort to exporting their product because of better returns. Importers from China, Japan and other countries offer better prices to them as compared to local market. Guntur in Andhra Pradesh is the main centre for production of Raw Cotton Linters.
