A few years ago we installed recycle bins on the corridors for guests to directly recycle their waste, however one thing you need to be aware of before installing anything in you corridors is the remaining width in the corridor after install against the total possible number of people whom may be trying to escape down it. Not looking into this properly lead to the removal of the bins 1 year later after a fire risk assessment.
This resulted in asking the room attendants to recycle what they found as best they can from guests over the interval which has worked quite well and we willcontinue to encourage this.
We have now just bought a smaller and quieter recycling system for each floor.
I say quieter because you also need to consider the noise produced from lifting bins lids and dropping say an empty coke can into the bin late at night.
