Cooking Oil Collection
The possibilities for reusing kitchen oil are many: soap production, detergent, glycerin, animal feed and even biodiesel!
Some of the hostels we visited collects the cooking oil used in their kitchen, and the guest kitchen, and makes soap out of it. Just like Maresias Hostel in São Sebastião. Maybe there are companies that collect used cooking oil in your neighborhood. Adrena Sport Hostel in Belo Horizonte collects their cooking oil in a big plastic container and donates it to local organization. Collecting the oil in used milk cartons like Hostel 7 in Goiania is also a great way of doing it. Why not do a little research to find out if you can donate your oil to someone who needs it?
The important thing is to avoid throwing cooking oil into the sewer because it pollutes nature and can cause obstruction of the pipes.
