MACS also developed a sludge concept for the construction of a modern Wastewater Treatment Plant. A market assessment resulted in a demand for sludge by small-scale farmers, gardening companies and the municipal park and greens management company.
Years later reality proves that there is a market for quality sludge. The sludge quality is analyzed on an annual basis and shows that the content is not only without risk, it’s also considered a good fertilizer rich in Nitrogen, Phosphate and Potassium. Customers conclude contracts with Batumi Tskali, take the sludge from the wastewater treatment plant and pay for it. This is considered a sustainable solution that makes use of finite resources.
