Additionally, the amounts of hazardous substances in furniture parts should also be limited to avoid their release into the environment during disposal. A take-back system could potentially be a good system to guarantee the recycling of products. However it may not be very practical to require the set up of a take-back system for all types of furniture. For this reason it is suggested to only impose criteria with respect to recyclability, but not to require the set up of a take-back system.
