«Organic belt around Kazakhstan cities – 2020» environmental project

Summary

The description of «Organic belt around Kazakhstan cities – 2020» environmental project that engages essentially the water industry and that is being implemented nowadays is presented. The timeliness of the project comes from the amendment of the national legislation, Article 301 of the Environmental Code of the Republic of Kazakhstan in particular (2016), that is related to the regulation of waste landfilling. The new regulatory document limits (and actually prohibits) storing dewatered wastewater sludge on landfills and prescribes to provide for its further processing with the purpose of transferring theses wastes from «hazardous organic wastes» category to recultivants, cultivation soil etc. The project envisages the use of Russian technology of wastewater sludge dewatering on sludge beds with the use of «Sibflok®» flocculant and the technology of enhanced composting of organic wastes developed by the experts of International Academy of Ecology (Astana). The implementation of this project will provide not only for reducing significantly the amount of municipal sludge transported to landfilling but also for establishing the production of soil-like substrates, soils for remediation of desertificated territories, landfills, dumps; and in case of advanced processing – for urban greening services.
