Normally, manufacturers 'recall' all products that are expired or about to expire. They keep it off the market to avoid costly litigation if these expired products go into unscrupulous people or even people who might get sick taking them.
These companies have contractors who collect all these and are likewise tasked to dispose of the products discreetly. However, they may also sell these to other users like feeds manufacturers and the like.
Unfortunately, I don't know any 'reverse logistics' company here in cebu, though I am sure there is. You might want to try SMC or other food manufacturers on what their procedure is for you to be able to buy these stuff...
