Abstract Gearboxes are usually lubricated with oil or grease to reduce friction and wear dissipate heat. However, gearbox applications that cannot be grease, for example in the space food industry, commonly solid lubricants. Especially lubricants a lamellar sliding mechanism like graphite molybdenum disulfide (MoS 2 ) diamond-like carbon (DLC) coatings can enable very low coefficients of fricti...

The feedstock used in our experiment for the production of biodiesel was Yellow Grease. The whole experiment was divided into two parts: Production and Testing. Production involves Transesterification of free fatty acids in yellow grease to form yellow grease alkyl esters. The process of testing involved calculation of the physio – chemical properties, acid value, density, kinematics viscosity ...

The grease and oil trap systems (GOTS) of four university food service establishments (FSE) were assessed treated to evaluate the potential use sludge collected produce compost. from each FSE was kept in a drying bed for 30 days (SDB), during which time calcium oxide frequently added stabilization. deposited monthly reduced half after process then composter mixed period 22 with constant agitati...

Abstract Oil and grease are organic contaminants that detrimental to the environment. The high concentration of oil can cause clogging in sewer. Clogged sewers deteriorate sanitary conditions. Adsorption is one technique reduce wastewater. using natural resources overcome cost commercial activated carbon. Sewage sludge has potential as raw material for carbon because content. studies aim invest...
