Operating and maintaining

Since 2014, we have helped optimize the performance of biomethane plants. To do this, we offer services that leverage all operational drivers requiring concurrent management.



As organic waste experts, we bring together waste producers and short-circuit plants to recycle waste and benefit the country as a whole.


Securing investment in your project

Creating a business plan

We offer step-by-step support in drawing up and finalising a business plan, ensuring that all the information is current and correct. We can also update your financing plan in line with banks’ requirements and criteria.

This process confirms the amount of investment required as well as reassuring banks, thus making it easier to secure loans.

Securing funding means ensuring peace of mind

Proving equity

To consolidate the funding for your project, we provide equity in two forms:

As share capital

We do everything in our power to support the project and ensure it is sustainable (money tied up in company capital).

As current accounts

The aim here is to optimise and maximise profitability for shareholders. Repayments can be spread over a seven to ten-year period with an identical interest rate for all shareholders.

Securing grants

We research all the different avenues available for securing subsidies on a regional and European level and via the French Agency for Ecological Transition (ADEME). We prepare detailed grant applications on your behalf, saving you time and maximising efficiency.

Drawing on our comprehensive knowledge of grant eligibility criteria and specific regional requirements, we also ensure you have the best possible chance of securing funding.

Boosting your chances of securing a loan

With years of experience and partners who specialise in securing bank loans, we ensure you have the best possible chance of obtaining funding:

our brokers can assist you in securing the most favourable terms.


Responsible and committed, TER’GREEN has long been a trusted client in the banking world. This familiarity will reassure many banks.


Why you can trust us

Having been a partner in many different biomethane projects over the years, we have the experience required to put together realistic business plans based on fair market prices.

Given that the markets are not fixed, we also rely on bankers and insurance brokers to monitor and safeguard the success of the project at every step, alerting us to any warning signs.
