BeFC Bioenzymatic Fuel Cells provide Eco-friendly paper-based bio-enzymatic fuel cells for sustainable energy generation. Electronics integration in disposable medical and wearable medical devices has become increasingly important. The button or coin cell power sources used are difficult to recycle, toxic, or dangerous to the environment. The development of safe and ecological devices is often a barrier to the progression of single-use and single-patient devices. BeFC offers a sustainable and eco-friendly solution for practical energy generation whilst minimizing the impact on the environment. We believe our approach will not only allow the replacement of batteries for existing applications, but also open up new opportunities for low-power ultra-thin health monitoring, logistics/transportation monitoring, and Internet of Things (IoT) applications.

Methaneo specializes in the development of collective biogas projects based on biomass of agricultural and agri-food origin. Anaerobic digestion is the fermentation of organic matter that produces energy through the biogas rich in methane released by this process. The company favors "territorial" biogas projects. The specificity of this type of installation lies in the association of a large number of local partners: suppliers of biomass and heat recovery (industrial, farmers and communities), unlike individual anaerobic digestion on the farm which usually involves a single actor.
JMB ENERGY is a producer of renewable electricity, which positions its activity in 2 key areas of renewable energy: the wind and solar photovoltaics. Ultimately, its development will enable it to expand its reach to areas of biomass, and the hydraulics.
