“…Contrary to the Netherlands, significant progress toward wastewater treatment and reuse has been made. Wallis-Lage et al (2015) suggest that the best option is an equal priority between the waste to energy (WtE) approach that uses the potential of sewage sludge (but also other organic waste) to generate energy, as well as the new nutrient-energy water paradigm (NEW), (Fig. 2).…”

“…An important issue is also the social acceptance of wastewater reuse directly from WWTP (Kehrein et al 2020). According to Wallis-Lage et al (2015), the water can be reused in: (i) agriculture/horticulture such as irrigation of crops (food and non-food), orchards and pastures or aquaculture including algal farming; (ii) industry such as cooling water, process water, aggregate washing, concrete making, soil compaction, dust control and/or iii) municipal/landscape uses such as irrigation of public parks, recreational and sporting facilities, private gardens, roadsides, street cleaning, fire protection systems, vehicle washing, toilet flushing. In the document, several environmental, economic and social benefits are shown.…”

Wastewater treatment plants (WWTPs) have become crucial elements of the regional bioeconomy—mainly through energy (waste to energy) and matter (nutrients–energy–water) recovery as an element of sustainable development of a smart city. In Poland, a decentralized system functioned with 3278 municipal wastewater treatment plants, and less than 80% of the population were connected to public urban wastewater treatment systems. The paper presents the technology selection and implementation of circular economy at WWTPs and the practical approach to challenge of energy-positive and environmentally friendly wastewater and sewage sludge sector. The modernization of technological lines of wastewater treatment has led to a significant improvement in the quality of treated sewage, at the largest WWTPs in Warsaw, Cracow, or Gdansk. Eleven WWTPs produce 34% of the total volume of approximately 337 GWh of electricity from biogas in Poland. The potential of producing electricity from biogas in WWTPs in Poland can be estimated at approximately 700–850 GWh per year. According to the data of the Statistics Poland in Poland, approximately 25% of sewage sludge was used directly in agriculture and for land reclamation. Simultaneously, more than 100 WWTPs produce compost at a high quality. However, only few produce organic/organic-mineral fertilizers, mainly with addition of calcium. Decentralization leads to different technologies used in wastewater treatment plants, and environmental, economic, and social conditions determine the direction of changes and introduction of a circular economy paradigm in the Polish wastewater sector.

Introduction of the circular economy package as a result of the necessity to protect natural resources has also forced a new approach for effective wastewater and biowaste treatment and management. Wastewater treatment plants (WWTPs) have become crucial elements of regional bioeconomy - mainly through energy (waste to energy) and matter (nutrients-energy-water) recovery as an element of sustainable development of a smart city. In Poland in 2019 operated 3278 municipal wastewater treatment plants. To achieve specific effluent goals for BOD, nitrogen and phosphorus, different adaptations and modifications have been made. Modernization of technological lines of wastewater treatment has led to a significant improvement in the quality of treated sewage, at the largest WWTPs in Warsaw, Cracow or Gdansk. Eleven WWTPs produce approx. 34% of the total volume of approx. 337 GWh of electricity from biogas in Poland. The potential of producing electricity from biogas in WWTPs in Poland can be estimated at approx. 700–850 GWh per year. According to the data of the Statistics Poland in 2019 in Poland approx. 25% of sewage sludge was used directly in agriculture and for land reclamation. Simultaneously more than 100 WWTPs produce compost at high quality. However only few produce organic/organic-mineral fertilizers, mainly with addition of calcium.
