The research objective of the study is the estimation of a novel low-cost composite material f-MB (Fe-modified bentonite) as a P and N adsorbent from wastewaters. Τhe present study aimed at examining the phosphate and ammonium removal efficiency from different types of wastewater using f-MB, by conducting bench-scale batch experiments to investigate its equilibrium characteristics and kinetics. The SEM analysis revealed that the platelets of bentonite in f-MB do not form normal bentonite sheets, but they have been restructured in a more compact formation with a great porosity. Regarding the sorption efficiencies (Qm), the maximum phosphate sorption efficiencies (Qm) calculated using the Langmuir model were 24.54, 25.09, 26.13, 24.28, and 23.21 mg/g, respectively, for a pH range of 5 to 9. In addition, the maximum NH4+-N adsorption capacities (Qm) calculated from the Langmuir model were 131.8, 145.7, 168.5, 156.7, and 159.6 mg/g, respectively, for a pH range from 5 to 9. Another important finding of this study is that f-MB can recover P from treated wastewater impacting on resource recovery and circular economy (CE). The modified clay f-MB performed the phosphate and ammonium recovery rates of 80% and 78.5%, respectively. Finally, f-MB can slowly release the largest proportion of phosphate and ammonium ions for a long time, thus extending the application of the f-MB material as a slow-release fertilizer and soil improver.

The circular economy is a topic researched by Wageningen University & Research (WUR). In addition to better waste management WUR strives to reduce the use of resources in its operational management. Recently WUR’s executive board ratified a Circular economy policy, vision & strategy 2019-2030. Aim is to achieve a 50% reduction in the use of resources in 2030, compared to 2014. This ambition follows the circular economy policy launched by the Dutch government.By buying fewer products, making smarter use of products, extending their lifespan and re-using products within WUR or elsewhere, WUR will reduce the number of resources used, as well as the amount of waste that is incinerated or recycled. In order to follow the progress of WUR’s circular economy policy WUR will also monitor the usage of resources, in addition to the current waste monitoring. Strategies proposed are to extend the use of products, to recycle products for new purposes, extending the lifespan of new products and to close the circle for new products fully. The success of WUR’s circular economy policy depends on acceptance and support by, and behaviour of students and employees whose expertise WUR will furthermore use where possible. WUR will also cooperate where possible with other organisations and companies.

The article considers the model of circular economy and the possibility of its implementation in Ukraine. The authors explore the main aspects of the circular economy and the relationship with the goals of sustainable development. It is noted that the use of innovations and innovation systems is the basis of the circular economy, which will ensure the interdependence between the reduction of non-returnable waste and increase the use of reusable resources, will not improve the ecological and economic condition of the country. The article analyzes the economic content of methods and models of implementation of the circular economy by identifying their impact on the sustainability of economic and government systems. The generalization of world experience in the implemented concepts of the circular economy allowed us to identify 5 main circular business models: circular deliveries, resource recovery, platforms for exchange and sharing, product as a service. The article gives examples of implementation of the principles of circular economy in the production of world brands. Prerequisites and recommendations for the introduction of a circular economy in Ukraine are summarized. It is determined that the introduction of a circular economy is beneficial for the enterprise or company, for consumers, communities and the state as a whole. The advantages in the long run on optimization of material flows, opportunities to enter new markets, expand the scope of services, obtaining additional profits in the field of services are highlighted. The interrelation of business models of circular economy recommended for use in Ukraine is established. The article identifies further steps of the study, which will be aimed at building a model of circular economy, based on the experience of leading European countries, taking into account Ukrainian characteristics, as well as detailed performance criteria for companies implementing circular economy depending on the scope and size.
