Become a circular leader with your product

Challenge Contents

Day 1: Materials

The first step in (re)designing circular products is looking at the materials that are the building blocks of your product. Identify the materials used in your product, their quantities and sources, to ultimately identify opportunities for more sustainable alternatives.

Day 2: Waste

Waste is a design flaw, meaning a poorly designed product creates more waste than necessary. Create awareness of your total waste production during the lifetime of your product and set clear goals to decrease your waste outputs.

Day 3: Packaging

Packaging items often consist of different materials and elements that pollute the environment in many ways. Alternative materials, bio-based packaging solutions and those that can be recycled are valid solutions to overcome those negative impacts. Learn how you can opt in for better packaging solutions that stress the environment less.

Day 4: Transport

Shipping, trucking and flying the raw materials, components as well as your product can result in a large amount of carbon dioxide emissions. Learn where the greatest impacts are for your product and what can be done to improve.

Day 5: Energy

Most of the negative impacts are related to energy use: local pollution, acidification of the oceans, carbon emissions as well as resource depletion. Identify the embedded energy in your product using our step-by-step worksheet and find out where energy use can be reduced or changed to renewable, low-carbon sources.

Day 6: Circular Design

In search of circular design, there are numerous valuable strategies to reduce negative impacts before, during and after the use of your product. Learn to apply different strategies and identify which strategy is suited best for (re)designing your circular product.

Day 7: Circular Business Models

A product can be very circular, but it won’t be able to achieve its full potential unless it meets the needs of your customers at a viable price. Without a business model, your product will not facilitate sustainable growth or propel your circular mission forward. Familiarize yourself with the most common circular business models with the help of our worksheets and videos.

Circular Engine has guided Omrin in the realization of the new strategy and in particular the route to a distinctive circular proposition.

Developing a circular vision, defining our circular waste processing concept and determining the relevant communities were important pillars of her work.

Nicole is a smart young woman with a clear vision of a circular economy, a healthy portion of critical thinking and the competences to make the right connections. I highly recommend working with Circular Engine.

John Vernooij

CEO, Omrin waste treatment

Through her knowledge, network, and supportive leadership, Nicole has helped many of my projects gain the traction and important insight into circular economies that they needed to grow.

Nicole helped turn our MIT Energy Hackathon event into a replicable model used by other top-tier institutions.

She also helped my international environmental restoration organizations, Beyond Coral and CHARM, gain the necessary traction through her university and United Nations platforms.

Without question, Nicole’s guidance and support have been a great benefit to my organizational mission and I would highly recommend working with Circular Engine.

Stephen Rodan

President, Beyond Coral Foundation

Nicole means a lot to OG Clean Fuels. She’s led our strategy process for Public Affairs and is pushing hard on the data-side for getting equal policy treatment of all sustainable fuels: a critical requirement to make the circular economy feasible and affordable.

Nicole is very knowledgeable, investigates topics in detail, and presents the findings in a creative and clear way. For example, we now have an interactive dashboard for sustainable road transport. How cool is that?! Lastly, she helped to set up a new department, and provided training and support for our new employees.

Still in doubt?

We designed the 7-Day Circular Business Challenge to give entrepreneurs and professionals a flying start in the circular economy. Below are a few reasons that may be an objection for you to start – with solutions.

I don't know if I can create circular product myself

No worries! We take you through the process in a step-by-step way, so that you are guaranteed to have workable documents. You can ask all your questions via e-mail or Instagram.

I don't have time to make my product more circular

Our advice: don’t do it alone! Involve teammates and colleagues in this. By taking action now, you are ahead of the regulations and your competition. In our experience it costs organizations much more time if they have to create a circular products at the last minute.

I believe this course is pricey

With guidance of Circular Engine, entrepreneurs have been awarded various subsidies, won competitions and tenders. The amounts vary from EUR 300,000 to EUR 1.5 million. As a result, some of them created a solid stream of income for the next 10 years. In short: you will earn back this investment.

By bundling our effective methods and offering them in course form, we can help more entrepreneurs at the same time and offer you the knowledge in a more affordable way than in our 1:1 consultancy trajectories.

I don't have a product yet

We recommend you to start with a tangible product in mind. However, through this program you’ll gain plenty of inspiration.

Did you know that circularity is expected to generate trillions of dollars for the economy by 2030?

Companies that successfully respond to this not only reduce their footprint, but also have their turnover increase exponentially.
