bayawan city biodiesel project

``

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

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

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
