Gate C is a consulting firm helping clients to capture the value of the circular economy






What we do

We help clients mapping the benefits and capture the value of the circular economy. We assist them in identifying, assessing and experimenting circular economy business models, such as product life extension, product as a service or industrial symbiosis.

Resource efficient, circular economy business models allow companies to improve their economic and environmental performance. According to the European Commission, circular economy could save business the equivalent to 8% of their annual turnover.

Business models

Why we do it

Most existing business models are not sustainable. They consume endlessly finite resources. At current consumption levels, phosphorus reserves will be depleted in around 80 years (MIT). By 2025, about 1.8 billion people will be living in regions or countries with absolute water scarcity (World Bank).

They also generate large quantities of waste that pollute water, soil and air. By 2050, there will be more plastic than fish in the sea. 33% of land is degraded due to, in particular, acidification and chemical pollution of soils (FAO). CO2 levels in the atmosphere are at their highest in 400,000 years (NASA).

What we have already done (examples)


For a packaging goods company, we delivered a one day course on alternatives to plastic to R&D, purchasing, packaging and marketing managers. We leverage hundreds of examples and cases studies.

Workshop facilitation

For a large consumer goods company, we assessed the benefits of paying chemicals per use rather than per volume. We identified that switching to a pay-per-use model would reduce chemicals total cost of ownership, in some cases, by 15%.

Waste-to-resource matchmaking

For a chemical producer, we identified industrial symbiosis in order to sell chemicals by-products rather than to pay for their disposal. We leveraged big data technologies to identified local customers for these by-products.

Workshop facilitation

For a retailer, we facilitated a half a day workshop on new business models for packaging.

Maturity assessment

For a global retailer, we assessed the reverse logistics maturity level and qualified improvement initiatives. We discovered that outsourcing collection would reduce reverse logistics costs by 30%.

Opportunity assessment

A global chemical company purchased 8 billion € worth of products and service worldwide. It succeeded in improving labour productivity but struggled to increase resource productivity. Together, we reviewed the existing sourcing strategies for industrial equipment used in more than 100 sites worldwide. We identified several circular sourcing strategies that reduced the TCO of several equipment by more than 20%.


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

Circular sourcing strategies

We have identified and qualified the 5 main sourcing strategies leveraging the circular economy. By improving material efficiency, circular sourcing strategies reduce costs and environmental impacts.

Case studies repository

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

Training on alternatives to plastic

We have designed a training on alternative to plastics for packaging. This training leverage hundreds of examples and cases studies.

Reverse logistics maturity model

The model assesses the reverse logistics maturity level. It considers five maturity levels: initial, managed, defined, quantitatively managed, optimizing. It describes the characteristics of successful reverse logistics processes across multiple dimensions.


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.

Matchmaking digital platform

We use a digital platform to match waste supply from one industrial process with raw material demand from another, turning "waste into wealth". The platform leverage big data, statistical data and machine learning technologies.


Featured insights

What are the alternatives to plastics?

Petroleum-based plastics cannot be sustainable but there are alternatives.

Waste watchers

Businesses have been making huge losses by failing to capture the value of industrial waste, but applying circular economy strategies, enabled by new technologies, could create cost-saving opportunities as well as profitable new revenue streams.

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.

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.

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.

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.

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.

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.

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.

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.

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?

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.

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: 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.

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.

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?
