Circular Enterprise (Cirkulær virksomhed) is a digital portal that gives SMEs information, inspiration and tools for promoting the circular economy in their businesses. Eight tools provide easy and clear instructions on how to promote their voluntary efforts for the benefit of the company's operations, product development, and communication with the outside world. 

The main idea of the tools is that they must be easy to use, relevant and adaptable to the needs of individual companies. With fewer dedicated resources, the tools thus provide SMEs a quick overview of how they can start promoting circular economy thinking. The tools cover a number of different areas such as eco-design, waste prevention, resource efficiency, cleaner production, new business models, and eco-labelling.

The portal was launched in September 2017 by the Danish EPA.
