How to unlock financial means for the purchase of a collective composter? Participation, reuse, grant, memberships, savings...

There are several ways to finance this type of project, you can use one or more.
The grant application option may take longer than the other options.


For the 60-household composter plan (which is quite large) provided later, the cost is around €900 to €1300 (depending on the type of wood and other materials).
In self-financing and self-construction, this amount is around €20 per household.


It is possible, among other things, to reuse some wood. This must be at least class 3 (made for outdoors).

If we collect wood, here is some useful info.


It is possible to apply for a subsidy or support for the construction by your municipality or other institution (Depending on who oversees waste management).
One argument can be the savings made following the “waste avoided tonnage”, i.e. the annual tons managed by the composter and no longer by your municipality or other institution.
The costs for the managers can be found in “about”.
Obviously, although important for funders, the economic aspect is not everything! Also talking about the social and environmental aspect is essential.


Having a membership system, even low (€5 per year) allows participants to be committed. In addition, it can cover the cost of tools, basic repairs or why not part of the training costs with a master composter or a collective composting structure!

Savings made

Depending on the costs associated with waste management and the methods used, you can save money by managing your “waste” in this way.
