On November 30, Semader put into service a first B:BOT in one of his residences, that of the bus station in Saint-Pierre. La B:BOT is a collection point for plastic bottles which crushes them to give them a second life and which gives the user a voucher for each bottle deposited. To begin with, these vouchers can only be used in the local Leclerc store. The approach is part of a broader program to improve waste management in Semader housing groups., launched in 2016, to which 760,000 euros have already been allocated.
