Wastewater and sewage sludge contain organic matter that can be valorized through conversion into energy and/or green chemicals. Moreover, resource recovery from these wastes has become the new focus of wastewater management, to develop more sustainable processes in a circular economy approach. The aim of this review was to analyze current sewage sludge management systems in Scandinavia with respect to resource recovery, in combination with other organic wastes. As anaerobic digestion (AD) was found to be the common sludge treatment approach in Scandinavia, different available organic municipal and industrial wastes were identified and compared, to evaluate the potential for expanding the resource recovery by anaerobic co-digestion. Additionally, a full-scale case study of co-digestion, as strategy for optimization of the anaerobic digestion treatment, was presented for each country, together with advanced biorefinery approaches to wastewater treatment and resource recovery.

Abstract This article describes the results of the conducted field experiment by using biostimulants “Uchkun”, “Super Uchkun”, “Gossipren” and “Verva” on cucumber varieties (Orzu) in Andijan region and the effect on the increase of productivity. It was revealed that the pre-sowing treatment of cucumber seeds with biostimulants promoted a significant increase in seed germination and growth processes. The most effective growth stimulant on Orzu cucumber was Super Uchkun. On average, the yield of cucumber when treated with biostimulants increased by 10.28%; 23.8%; 24.27% and 14.29%, respectively; while the yield increase was 1.3, 2.3, 2.7, and 0.9 t/ha, respectively.
