Recent Sustainable Technology Advancements for a Circular Economy

An international team of researchers has published a study in Clean appliances and technology exploring the latest advances in the circular economy and advances in related technology applications. Emphasizing the key role of an interdisciplinary, interconnected and international approach to sustainability, the authors presented a comprehensive overview of this area.

The issue of sustainability

Current world events have shown that anthropogenic climate change is a very real phenomenon that has far-reaching implications for the future development trajectory of modern industrial societies. Population growth and, as a consequence, rapid urbanization and industrialization have led to increased carbon emissions, waste and pollution, and the problem is exacerbated.

Although emissions decreased during the COVID-19 pandemic due to declining commercial and industrial activity and energy demand, they quickly returned to pre-pandemic levels, and the resulting effect of a sudden increase in electricity demand was an increase in coal production. at 43%. electricity. Although this was due to current coal production capabilities rather than the installation of new infrastructure, this is still a concern.

Aside from the dangers of greenhouse gas emissions, it makes no sense to continue to rely on fossil fuels from an economic standpoint when renewable energy becomes more commercially viable. Sixty-two percent of newly installed renewables are cheaper than the cheapest new fossil fuel alternative.

The recent rise in natural gas prices has exacerbated the economic problems associated with the continued use of fossil fuels. In addition, these resources are limited and the world will face potential supply cuts in the not too distant future.

The current paradigms of production and production operate on the principle of linear economy, when the resource can not be reused. Another way of thinking is to view waste as a valuable resource that can be used to produce new value-added products. The construction, electronics, plastics, mining and many other industrial sectors are now advancing towards what is called a circular economy, where secondary resources are primary resources rather than finite, primary ones.

Improving the sustainability of every sector of industry and society is a key issue in 21street century, when humanity wants to achieve the climate change goals set out in international agreements such as the Paris Agreement and COP26. However, there are now a variety of issues that need to be effectively addressed by international organizations, governments, industry and public sector bodies.


Write to Clean energy and technology, the authors of this paper gave an overview of current technological advances in improving the resilience and moving society and industry to a circular economy model. The work expands previous research by emphasizing the role of cleaner technologies and analyzing current research trends that are in line with the objectives of recent international agreements and conferences on sustainability.

Several perspectives have been presented in the study of current world events and how they can contribute to the movement towards a more sustainable future. The authors said the COVID-19 pandemic could provide an opportunity for a greener future.

Despite the disposal of personal protective equipment, medical waste, test kits, etc., the pandemic has provided unique opportunities that have been discussed in detail. One study suggested the best waste management systems where recycling systems can be based on energy recovery, on-site chemical production and renewable fuels. Sustainable vaccine management practices need to be implemented because of economic, environmental and energy impacts.

In addition, the recent and current energy crisis has highlighted the benefits of a decentralized system of energy production based on renewable sources. In addition to reducing emissions, such a system will provide countries with better energy security. Breaking global supply chains and rising fossil fuel prices require a different, more sustainable approach to the energy sector.

Another recent progress that is being discussed in the study in terms of international policy is the introduction of the EU carbon adjustment mechanism, which requires that all imported products meet the requirements by 2026. Importers in the areas covered by the mechanism must declare embedded emissions in their products. It is expected that this regulation will encourage producers to adopt green production practices in line with sustainability and the circular economy.

The document also discusses green hydrogen, which is one of the main candidates to fill the energy gap caused by the gradual abandonment of fossil fuels. In addition, the ecological production of electricity, biofuels, bioliquids and biogas are discussed in terms of how they can help achieve sustainability and cyclicality.

Although the separation of the economy from fossil fuel use is a complex and complex technological, economic and social process, the study notes that twenty-one countries are already achieving this goal, demonstrating that it is possible. An interconnected, interdisciplinary and intergovernmental approach will be needed.

In addition, the authors noted the increasing penetration of the topic of cleaner technologies in research over the past three years, demonstrating interest in the importance of circular economy principles. In addition, they stated that environmental management is the foundation of sustainable development, and cleaner technologies provide the technical tools for a system-wide global transition.
