Gate C is a consulting firm helping clients to map the benefits of the circular economy






What we do

Many existing business models are resource inefficient. By adopting circular economy business models, most industries could improve their economic and environmental performance. But a transition towards a circular economy faces many challenges and raises many questions: How to map the benefits of a circular economy? What are the most relevant business models per industry? What are the required capabilities and how to fulfil them?

We work with clients to overcome these challenges and respond to these questions. We help clients mapping the circular economy benefits. We assist them in assessing and experimenting a circular economy business model, such as remanufacturing, refurbishing or pay-per-use services. We deliver industry or company specific trainings. to allow them building circular economy capabilities.

Examples of our work

We work will clients from a wide range of industries. For example, we worked with a leading industrial equipment manufacturer to explore remanufacturing opportunities for their end-of-life products. We selected the equipment that were a good fit for remanufacturing. We evaluated remanufacturing return on investment and environmental benefits. Finally we produced a roadmap to experiment and rollout remanufacturing across product lines and geographies that would increase company turnover by 10%. We worked with a large consumer goods company to assess the potential of chemical leasing. We conducted a thorough review of chemicals purchase, use and disposal. We identified four chemicals that were a good fit for chemical leasing. Through a series of workshops, we identified, with chemical suppliers, the benefits of switching from a pay-per-volume model to a pay-per-use one. We conducted a training for a high tech company to build its reverse logistics capabilities.


We offer proprietary tools and databases to accelerate and increase impact.

Business models repository

Mapping the benefits of a circular economy requires an in-deep understanding of each circular economy business model. There are six main business models, from pay-per-use to sharing economy. We have build a business models repository that qualify each business model: benefits, limits and challenges. The repository details the model per industry: remanufacturing, refurbishing, predictive maintenance, chemical leasing, etc.

Case studies

Transition towards a circular economy is not yet an common journey. Leveraging lessons learned from existing initiatives is critical. Therefore, we have consolidate hundreds of circular economy cases studies. These cases studies allow us to quickly demonstrate circular economy benefits for a given industry or function.


Based on the analysis of hundreds of case studies, we have designed a robust methodology to implement successfully circular economy business models. This 3 steps methodology helps clients identify, qualify, experiment and roll-out circular economy business models. It has been summarised in our latest book.


Featured insights

Circular molecules

The circular economy and digitalisation will be the two most important trends employed by Germany’s chemical industry as it moves towards 2030. These trends, according to the German Chemical Industry Association, will “fundamentally alter the way” the industry is working.

Making products last

Today, as they demonstrate major economic, social and environmental benefits, remanufacturing, refurbishing
and repair need to be better supported
by governments, businesses and, also, consumers. Thanks to them, products are
not just consumables anymore, they become assets, our assets.

The machines that predict the future

The time when flights were cancelled, trains were delayed and elevators broke down may soon be over. Today, products are able to predict their own future. Thanks to predictive maintenance, they can forecast failures before they occur.

The missed opportunity of purchasing departments

In France, few purchasing departments are leveraging the benefits of a circular economy. Yet, for some purchasing categories, circular economy reduces costs, resources consumption and greenhouse gas emission.

Why reverse logistics is an essential part of a circular economy

For a long time, reverse logistics has been seen only as logistics going in the “wrong direction”. But that should no longer be the case. Today return flows are becoming the norm rather than the exception. By closing the loop of product lifecycles, reverse logistics plays an important role to transitioning to a circular economy.

Ending e-waste

Electronic and electric equipment manufacturers are amongst the world’s most innovative companies. They are working hard to make everyday life easier. But so far they’ve taken little advantage of their unique capacity to adopt circular design approaches and invent more effective production and use models, or reduce the use of high value materials. And that needs to change.

Waste + Information = Resource

Circular economy principles rely on a very simple equation, “waste = resource.” However, the reality is somewhat different. Making used equipment “as good as new” is difficult without information regarding its design or its past use.To maintain the value of materials and products in the economy for as long as possible, the circular economy needs to have access not only to waste, but also to information regarding said waste.

Towards factories with no assets

Switching to pay per use services is a great way to reduce or eliminate capital intensive investments such as hardware and facilities, while significantly curtailing overhead costs in management and maintenance. Yet, if such services are common on the office floor, they still barely go through the factory door. But, slowly, change happens.

How circular economy can reduce French hospital costs by one billion euros

Unlike many other sectors, hospitals have not yet fully optimised their production resources. Circular economy can help.

To improve public procurement, circular economy can help

With a debt exceeding two trillion euros, the French administration must reduce its expenses. It must reduce, especially, public procurement amount which represents 10 % of the country GDP. Surprisingly, France barely leverage circular economy to reduce public procurement amounts, unlike several other European countries.

Can emerging countries benefit from the circular economy?

Developing countries have not benefited from the linear economy. They have poor access to cheap goods to improve the quality of life of their populations. They do not take advantage from the extraction and exportation of raw materials to developed countries. Conversely, they have large quantities of waste brought in from developed countries. Can developing countries better capture the value of the circular economy?

Remanufacturing: a unique opportunity for the French industry

Remanufacturing reduces manufacturing costs, diminishes resource consumption and creates jobs. In Europe and in France especially, it still remains underdeveloped. But this is not a fatality.

Circular economy: the emergency exit of the mass-market retail sector?

Squeezed between product price increase and consumer purchasing power decrease, challenged by new consumption models (such as online sales), retailers have to face many challenges. But circular economy can help.

Creating jobs, saving resources

For decades, industrial companies have improved labour productivity to reduce their costs. But labour represents only 17 % of their costs against 45 % for raw materials. Companies should focus on resource productivity, and create jobs.

Resource productivity should be factories next priority

Materials represent 50 % of an industrial company production cost. To reduce these costs, factories should not limit themselves to incremental improvement programs such as lean manufacturing or zero waste projets. They should implement resource efficiency programs.

Circular economy: which strategies for cities?

The world's cities occupy just 3 % of the Earth's land, but account for 75 % of ressource consumption and 50 % of waste production. A growing number of cities are willing to adopt circular economy models. But, unlike corporations, they are crossed by countless flows of resources. What are their possible strategies for a transition towards a circular economy?

Reversible reaction: Even chemicals can be leased

At least 140,000 chemicals are used globally in a wide variety of products and processes. While they largely contribute to the economy, they expose human health and the environment to major risks. An innovative model may help to drastically reduce these risks.

Circular economy for the construction sector: Beyond material recycling

Responsible for 73% of waste production in France, the construction sector should accelerate its transition towards a circular economy.
