Sewage waste to become plastic
Cleanzine has just got wind (sorry - couldn't resist that!) of a pioneering, groundbreaking innovation that will help turn municipal sewage sludge into raw materials, to be used by paper and plastics industries around the world.
The technology, developed by Israeli company Applied Cleantech, has been some years in development. It has resulted in a compact, automatic and efficient facility that recycles solids from raw sewage and turns them into high-quality consumer products through a continuous process (SRS- Sewage Recycling System).
Aside from the raw materials created at the end of the process, the new plants assist in reducing regional sewage purification plant loads by about 35%. As a result, purification plants enjoy reduced energy consumption and reduced operational and maintenance costs in their water cleaning process in favour of reuse.
In addition, sewage recycling provides three major benefits. First, reducing regular operational costs by approximately 30%, as well as gaining raised capacity. Second, manufacturing and selling high quality consumer goods by utilising sewage materials, and third - reducing greenhouse gases. This system can turn purification facilities into a true asset - a source of income and positive environmental contribution.
The company's development was intended to provide a solution for issues in sewage care. Today, a certain percentage of the massive amount of waste produced by human beings (solid municipal waste) is cleared through garbage systems to landfills, and some is cleared through the sewage system through sewage purification facilities. The raw sewage that reaches the sewage purification facilities contains suspended solids, soluble solids, minerals, oils and toxic compounds. Speaking in environmental terms, sludge is currently considered one of the major issues that need to be solved.
"The revolution is in regarding these solids not as waste that must be hidden, consumed by bacteria, or buried, but as a resource and base for raw materials that is sold back to the industry," says Dr. Refael Aharon, CEO and founder of Applied Cleantech.
"For the first time ever, this technology is able to recycle solids in wastewater and turn them into raw materials that can be used to manufacture paper and plastic. It is currently being utilised in a few cities around the world, and in advanced negotiation phases with municipalities and investors in Europe and the United States."
