<p>Nowadays the global ecological crisis continues aggravating. The environmental issues are on agenda, getting increased public attention (e.g. protests caused by waste problems and climate change all around the world). Depleting resources, trash mountains, garbage islands, toxic emissions etc. require change of economy model from linear (resource extraction-production-usage-throwing away) to the circular one (recycled resource-production-usage-recycling). More than that, multiple waste use as well as resources reuse may bring to business and economy billions of dollars.</p><p>The very idea of recycle is practiced in the world since long ago. However, it has been done by few resources (collection of waste paper, scrub metal, glass bottles etc.) without shaping an economic system as a whole.</p><p>Another problematic issue is that the recycling does not always means to be ecological. The mode of recycling in countries with low eco-standards results in heavy pollution (e.g. e-waste &#8220;recycling&#8221; by fire at open air in Africa, India leads to emission of toxins; ship recycling in Bangladesh leads to polluted beaches and water). Methods of recycling in developing countries often are primitive and may be dangerous. Sometimes, entrepreneurs from developed countries are responsible for such state of affairs. They send legally or illegally part of wastes for that primitive recycling in developing countries. It is important to have awareness of the fact that everything is interdependent. If one part of the Earth is full of toxins and harmful fumes, its other part is inevitably affected over time. It is necessary to carry out recycling in all countries establishing strict environmental laws worldwide, and to make it based on smart technologies.</p><p>Circular economy in its narrowest sense is an economy that simply processes waste.<br>A serious change in business models, public mentality and government policies is necessary to get to environmentally friendly economy. It aims at lengthening the use cycle of goods (e.g. clothes, mobile phones) and minimizing the personal waste of every citizen. The EU household&#8217;s food waste was estimated to be 47 million tons (EU FUSIONS, 2016). &#8220;More than 30% of clothes in Europeans&#8217; wardrobes have not been used for at least a year. Once discarded, over half the garments are not recycled but end up in mixed household waste and are sent to incinerators or landfill&#8221; (EPRS, 2019). YouGov Omnibus research: a third (34%) of respondents of Singapore have thrown away an item of clothing after wearing it just once. (YouGov, 2017).</p><p>Thus, effective circular economy is not just about re-processing and saving resources but, first, emphasizes its focus on greening environment and reducing waste as it is, becoming an eco-circular economy. Secondly, it calls forth measures at not only national or regional level, but also proceeding from &#8220;Earth is our common home&#8221;, worldwide.</p>
