With the growing quantity of waste generation, the waste management has become an essential issue that needs urgent attention and action. There is a need for a more sustainable approach to waste management, and the solution could be the circular economy concept (Ribi´c et al., 2017).
Waste management and the circular economy are closely related and mutually dependent concepts that have gained increased attention from policymakers and eco-conscious companies in recent years. Waste management involves the collection, transportation, and disposal of waste materials through various methods, such as landfilling, incineration, or recycling (Nanda & Berruti, 2021). On the other hand, the circular economy is an economic model that aims to keep resources in use instead of throwing them away by designing out waste and pollution, keeping products and materials in use, and regenerating natural systems.
The traditional linear economy model, which is based on a take-make-use-throwaway approach, is no longer sustainable given the growing population, the limited availability of resources, and the pressing environmental issues we face today, such as climate change, air, and water pollution (Dissanayake, 2022). Therefore, the circular economy offers a more sustainable alternative that benefits the economy, society, and the environment. It promotes a closed-loop system that emphasizes waste reduction, reuse, refurbishment, and recycling instead of the linear model’s end-of-life disposal (Rajak et al., 2022).
Waste management plays a critical role in supporting the circular economy by collecting and separating waste materials that can be reused in the production process (Arena et al., 2021). For example, recycling plastic bottles can go a long way in reducing the demand for virgin materials and cutting down on greenhouse gas emis-sions associated with extraction and transportation. Waste-to-energy technologies, such as incineration or gasification, can also be used to convert waste into energy, reducing reliance on fossil fuels and mitigating climate change.
One prominent example of a company that has embraced the circular economy is the multinational IT giant, Dell (Zhang et al., 2022). The company has implemented a closed-loop recycling process that collects used computers, recycles them into new ones, and sells them back to customers. Dell’s approach not only reduces waste sent to landfills but also delivers cost savings and energy efficiency benefits.
Another example of a circular waste management system is the city of Amsterdam’s approach to managing biosolids, which are the solid by-products from wastewater treatment. Amsterdam has installed an innovative facility that processes biosolids into phosphorus, a vital ingredient in fertilizer (Gianico et al., 2021). By doing so, the city has reduced the environmental impact of waste disposal and prevented the loss of valuable resources.
The relationship between waste management and the circular economy is symbi-otic, with each supporting and reinforcing the other’s goals and objectives. Waste management helps to ensure the efficient collection, separation, and processing of waste materials that contribute to the circular economy’s closed-loop system. The benefits of adopting a circular economy model are significant, with reduced waste and pollution, new business opportunities, cost savings, and more sustainable economic growth (Androniceanu et al., 2021). While implementing a circular economy requires significant investment from governments and companies, the potential rewards are well worth the effort.
