I saw the following question. It is puzzling not because of the grammar, but the meaning of 'need':
In the past we threw a lot of our kitchen waste away, but today many itmes such as plastic bottles and newspapers _______.
There are only two possible choices, one being "are recycled" and the other "need recycling", but the answer given is "are recycled". Does anyone know why "need recycling" is incorrect, or is it really incorrect at all? Some people say 'need recycling" is illogical here, because such items as bottles probabably also needed recycling before. But I was wondering whether 'need recycling' can be justified by the fact that the need stems from the law.
I'd appreciate your help.
