This article elaborates the role of soil and land management in a circular economy. The circular economy is highly dependent on the functioning of soils and land for the production of food and other biomass; the storage, filtration and transformation of many substances including water, carbon, and nitrogen; the provision of fresh mineral resources and fossil fuels; and the use of their functions as the platform for nature and human activities. Resource demand is increasing as a result of the growing human population. In addition to the shrinking availability of resources resulting from their unsustainable use in the past, our planet's diminishing potential for resource production, due to a range of reasons, is leading to resource scarcity, especially in the case of depletable resources. As an economic system that focuses on maximizing the reuse of resources and products and minimizing their depreciation, the circular economy greatly influences, and depends on, soil and land management. The concise management of the resources, land and soil is thus necessary, to make a circular economy successful.

This study investigates the effect of fibers from cotton and polyester textiles on the properties of fiber-reinforced polypropylene (PP) composites aimed at durable and load-bearing materials. Herein we developed a process-centered strategy to introduce 52 wt% of fibers within the thermoplastic matrix, while ensuring proper interfacial coupling. We examined the mechanical, thermal, and rheological properties of composite materials that integrated cotton and polyester waste fibers into PP matrices with different coupling agents.

The circular economy (CE) has become key to achieving the environmental objectives set by the European Union (EU). This transformative process requires linear production processes to be abandoned and replaced with environmentally-friendly circular models. In this scenario, the present study uses Data Envelopment Analysis and the Sequential Malmquist Index to achieve a twofold objective: (1) to analyse the effectiveness of the national CE policies applied by 19 EU Member States and (2) to identify the items of circularity that need improvement, in order to support decision-makers in the implementation of appropriate CE policies.
