Our Impact
To put it short, we vividly hate waste.
And we will spend all efforts needed to erase yours or make the most of it as resources, whether it sleeps in your warehouse as non-quality material, harms badly your colleagues as hazardous waste,
congests your production cycle and takt time, consumes avidly your water or electricity on bills, or sits comfortably in your balance sheet as excess inventory.
​
We genuinely believe sustainability impact starts with lean and healthy operations from the ground.
We are keen to support development or institutional projects on the field (public, private or NGO),
and factories & workshops looking to integrate a sustainable approach into their business.
Our summarized approach is:
- No time waste or breakage in your workshop with lean production and preventive maintenance
- No water, energy waste in your office/factory through resources optimization
- No hazardous waste harming your teams thanks to safe recycling (only electronics for now)
- No material waste during inventory and warehousing movements
