Wastewater Transformed into Raw Materials Generates Revenue for Dutch WWWP
Applied CleanTech (ACT) ran a trial of its Sewage Recycling System (SRS) with the Dutch Waterschap Aa en Maas (WSAM) and succeeded in reducing daily operational costs by approximately USD$2,700 in addition to reducing sludge by 30%. WSAM also recently released a report focused on the commercial potential of sewage mining.
Applied CleanTech's SRS system transforms wastewater into Recyllose™ (recycled cellulose), a raw material that has numerous applications in various industries.
According to the report released by WSAM, wastewater treatment plants (WWTPs) using ACT’s SRS can save approximately $2700 (~ EUR2200) per day in costs (for WWTP treating sewage of a medium size city).
"Do you want to let your children live in a world in which there are serious shortages of raw materials, or do you want to work together to create systems that properly maintain the raw materials so that they can continue to be used?" asks Piet Beltman, member of the Aa en Maas Executive Board. "For that you need innovation, and if you want to make a difference, you must realize smart, innovative solutions. Sometimes they come from outside the Waterboard."
According to the report, Recyllose™ was found to have many promising commercial uses as an economic substitute to cellulose in various industries. Recyllose™ can be used for the production of bio-composite materials, biofuels, asphalt, insulation materials, as a replacement for fiberglass, and more.
"The Recyllose that is taken out of the wastewater at the beginning of the process can be used efficiently and does not need to be thrown out to landfills," says Johannes Boersma, Aa en Maas Project Leader. "So actually, there is a double advantage here."
ACT's patented technology enables municipal, industrial and agricultural wastewater treatment plants all over the world to convert their wastewater into high-quality revenue-generating raw materials instead of producing expensive sludge. The converted wastewater can then be used in the global plastics, insulation, pulp & paper, construction, bio-fuels production, and nano-cellulose industries.
The Dutch WWTP reported several benefits to using the SRS technology: 31% savings on overall wastewater treatment OPEX, up to 30% reduction in sludge formation, reduced energy consumption and decreased load (pollution equivalents) to the biology used for the treatment process, and a 15% increase in the WWTP capacity.
