bayawan city biodiesel project
DESCRIPTION
Bayawan City trailblazing towards fuel and energy self sufficiencyTRANSCRIPT
``
Bayawan City Profile Population : 110,250 Area: 69,908 hectares (largest in Region 7) Mostly hilly with mildly sloping to rolling terrain Current / Emerging crops: sugar, rice, corn,
coconut / rubber, jatropha, coffee Fishing is a major industry (a tuna “highway”)
3rd class component city (CY 2007) 28 Barangays (7 urban, 21 rural) 80% of land area is rural Aims to be the Agriculture Capital of
Negros Oriental
Municipal waters is 225 sq kms
LGU’s Carbon Footprint
City has more than 100 diesel powered trucks, tractors, bulldozers, and other heavy equipment
City consumes an average of 75,000 liters of diesel fuel/month
Appetite for Fuel:
Economic development feeds on energy.
The Biodiesel Advantage• A substitute fuel derived from plant oils• Can be used directly on existing diesel
engines; no need for modifications• Lesser and cleaner emissions• Bio-degradable, safer to handle• Renewable and can be locally produced• Contributes to rural development • Keeps engine cleaner and more efficient

Learning by Doing
Creation of Research and Development Team on Biodiesel Production on May 15, 2006
R & D team presents first batch of coco-biodiesel sample to the City Mayor on July, 2006
In a year’s time, the team was able to:
Establish suitable processing methodsDetermine oil extraction methodsDesign a small-scale processing plantConduct initial tests on vehicles
Process FlowMethanol = 20% of volume of oilCrude

TRANSESTERIFICATION(stirred / mixed for 1- 2 hours

Sowing the Seeds of Industry
Seed oil is inedible…thus cheaper feedstock for biodiesel
Can be intercropped with coffee, corn, mongo, among others
Productive life is 40 years and with proper cultural practices, can yield 2 to 7 tons of seed per hectare
A hardy perennial, Jatropha curcas (tuba-tuba) was adopted by the LGU for agro-forestry as bio-energy crop
Dry Jatropha seeds have 30% oil content by weight
Scale Design of Bayawan City’s batch processing biodiesel plant.
1st test run using 95 % jatropha biofuel on March 6, 2008
Validating Jatropha’s Horsepower
PGMA inspects jatropha biodiesel powered vehicle of the city
Mixture of 50% petroleum diesel, 45% raw jatropha oil, and 5% Coco biodiesel
Towards Energy Self-Sufficiency
Total approximate outlay for bldg and equip: 1.5 M pesos
Designed for 100 liter per batch processing, scalable to 2000 liters daily production
DOE Sec. Angelo Reyes checks out the city’s biodiesel project
Processing plant with lab / office
Oil Expelling – A Vital Component
Newly acquired coconut oil expeller being tested at the
city’s biodiesel plant
Variations in the use of a manual expeller used for jatropha seeds
PLANT OIL STOVE
Raw jatropha or coconut oil can also be used as fuel for cooking

Taking the nautical highway on 100% biodiesel
City Mayor’s service vehicle has been running on 100% coco biodiesel for more than 9 months
Total distance traveled as of June, 2009: 23,459 kms.

Challenges and Directions Improvement of production facilities
Long term tests with city’s vehicles
Supply of methanol
Sharing of technology
Jatropha Intensification Project to establish 500 hectares plantation
Tapping of LGU’s coconut resources
Coconut-for-fuel sharing scheme
Back to the Future…Now“The diesel engine can be fed with vegetable oils and would help considerably in the development of agriculture …,”
June, 2004 issue
“The use of vegetable oils for engine fuels may seem insignificant today. But such oils may become in course of time as important as petroleum and the coal tar products of the present time.” - Dr. Rudolf Karl Diesel, 1912
