Abstract

Providing the farmers alternative sources of fuel such as biodiesel produced from waste cooking oil is one possible way of helping them reduce their dependence on fossil fuels. Waste cooking oil (WCO) can be a stable source of feedstock for biodiesel production since it can be easily accessed from restaurants and fast food establishments. If farmers would be able to use biodiesel, not only will they have a cheaper source of fuel for their farm equipment but they will also aid in the reduction of greenhouse gas emission. Moreover, they can have the chance of earning additional income from glycerin, a by-product of the biodiesel processing that could be used to manufacture soap, among other possible products. The utilization of waste cooking oil for biodiesel production could also help solve the problem of its improper disposal which would lead to some serious health issues. This study was therefore conducted to: (1) gather baseline data in the processing of waste cooking oil to biodiesel, (2) develop a system for a large scale processing of waste cooking oil to biodiesel, and (3) test the performance of biodiesel on different rice farming machinery. The cruzesterification process developed by Dr. Rico Cruz was adopted in processing the WCO into biodiesel. To account for the varying quality of purchased WCO, each container purchased from local food establishment was subjected to testing to determine the proper amount of KOH to be used per batch of mixing. It was observed that highly reused cooking oil required up to 21 grams KOH per liter of WCO with a conversion rate of 72-75%. WCO which was relatively less degraded on the other hand only required 11-15 grams KOH per liter of WCO with a recovery rate of as much as 92-95%. Using a fabricated micro-processing plant, the production of biodiesel in larger volumes was tried to enhance the system of production and utilization of biodiesel from WCO for farming operations. The processed biodiesel were tested in PhilRice-CES farm machinery in different blends: B20, B50 and B100. B20 and B50 biodiesel blends were tested in a 75hp four-wheel tractor. Moreover, B20, B50 and B100 biodiesel blends were tested in an 8hp diesel engine. One notable difference was that colorless smoke came out of the exhaust pipe in engines run on biodiesel blends as compared to the black smoke emitted in 100% petroleum diesel fuelled engines. No notable performance difference was observed in the engines run in biodiesel blends compared to 100% petroleum diesel.
