Abstract: The present invention provides a method of producing fatty acid alkyl esters from a lipid, comprising steps of introducing a gas comprising vapor of an alcohol selected from methanol, ethanol, 1-propanol, iso-propanol and butanols, into the lipid in a form of bubbles to enable the bubbles to pass through the lipid and be discharged from the lipid. The product may then be subjected to a transesterification process catalyzed by a base catalyst. The present invention is robust with low quality feedstocks thus significantly reduce production cost for biodiesel.

Abstract: The invention includes a litter box with an associated cleaning assembly that may utilize a bag and a box frame that may include a storage area for the assembly. The litter box has a rectangular frame with an open top and a floor separated by four integral walls. The cleaning assembly includes two rakes that each have a handle with several spaced apart teeth. Each tooth has an end and a tip. During use, the rakes slide across the box top while engaging the litter disposed therein. The teeth are inserted into the litter at each end of the box against the slanted end walls of the box by pressing the tips into the litter mass adjacent thereto. Then the rake ends are pushed inwardly until they reach the floor. The rakes then slide forwardly until the rake handle rests on top of the box frame.
