Implementation tokens converted into product vouchers cannot be reused or recycled to create more vouchers. Once an implementation token is converted, it is permanently transformed into a product voucher, which is irreversible. This means careful consideration should be taken before converting implementation tokens into product vouchers, as the decision is final. The ability to convert tokens is designed to provide flexibility in allocating resources towards sustainable practices. Still, with the understanding that once allocated, the direction of these resources cannot be altered. This ensures that the allocation of resources towards sustainability efforts is deliberate and final, encouraging thoughtful planning and utilisation of available tokens.
