Starch is an abundant material because almost all major agricultural crops contain starch. Potatoes are commonly grown in colder climates, while cassava is an important source of starch in tropical regions. Various grain crops also contribute significantly to the world’s starch supply.

With sufficient sunlight and water, agricultural crops can produce substantial amounts of starch dry matter. Modern processing technologies make it possible to extract starch from agricultural crops with high yields and a high degree of purity.

These characteristics make starch one of the most versatile raw materials for both the food and chemical industries. At its basic level, a starch granule is a compact structure consisting primarily of glucose polymers.

Bioethanol has been used as a vehicle fuel for more than a century. Henry Ford even designed the Model T to run on ethanol. However, the rapid development of the petroleum industry later made fossil fuels the dominant source of energy for transportation.

As interest in renewable energy continues to grow and the need to reduce dependence on fossil fuels becomes increasingly important, bioethanol has once again attracted attention. One agricultural crop with considerable potential as a feedstock for bioethanol production is cassava.

Cassava is particularly interesting because its roots contain starch that can be converted into sugars and subsequently fermented into ethanol. In tropical regions, cassava can also grow well under warm conditions and, depending on the production system, can be harvested throughout the year.

The Thai tapioca industry is expected to focus on tapioca flour exports and Asian markets as part of its growth strategy over the next five years. Industry representatives believe that the value of Thailand’s tapioca exports could reach 100 billion baht as demand for cassava-based products continues to expand.

The strategy reflects Thailand’s effort to strengthen the value of its cassava industry by placing greater emphasis on processed tapioca products, particularly flour. At the same time, the growing demand for cassava as a feedstock for ethanol production is expected to increase competition for domestic cassava roots.

The Commerce Ministry projected that by 2016, domestic demand for cassava roots for ethanol production could surge to 13 million tonnes. Meanwhile, exports could exceed 22.5 million tonnes, bringing total demand to approximately 35.5 million tonnes. This would represent an increase of around 42% from the production level at the time.

The Thai tapioca industry is expected to focus increasingly on tapioca flour exports and Asian markets as part of its growth strategy over the next five years. At the time, industry representatives were optimistic that exports of tapioca products could eventually reach 100 billion baht.

The strategy reflects a broader effort to increase the value of Thailand’s cassava industry. Rather than relying heavily on exports of tapioca chips and pellets, Thailand planned to strengthen the production and export of tapioca flour, which has applications across the food, energy, and other industrial sectors.

The Commerce Ministry projected that by 2016, domestic demand for cassava roots for ethanol production could rise to 13 million tonnes. At the same time, exports were expected to exceed 22.5 million tonnes. Combined, this would bring total cassava demand to around 35.5 million tonnes, approximately 42% higher than the production level at the time.

Cassava prices continued to move upward into the second half of 2011, although the pace of increase was slower than in the previous year. Data from the Ministry of Commerce showed that the consumer price of cassava increased by 1.13% during the first half of 2011, rising from an average of Rp 2,988 per kilogram (kg) in January to Rp 3,022 per kg in June 2011.

The increase was also reflected at the farmer level. Rhomy Irawan, Second Secretary of the Cassava Farmers Association of Indonesia (Aspesindo), said that fresh cassava prices had risen significantly. The average maximum price increased from around Rp 600–650 per kg to Rp 900–1,100 per kg, although prices varied depending on the cassava variety and accessibility of the cassava plantation.

“The price of cassava has increased beyond our expectations. This might be because there has been an increase in demand. But we still need to observe whether the increase is only temporary because of speculators or whether it will remain stable,” Rhomy said by telephone on Tuesday (5/7).

The International Institute of Tropical Agriculture (IITA) has emphasized that Nigeria needs to give greater attention to value addition if it wants to further increase cassava production and gain more economic benefits from the crop.

According to IITA Director General Dr. Peter Hartmann, improving cassava processing could do more than increase farmers’ incomes. It could also help address unemployment by creating additional economic activities and income opportunities in cassava-growing communities.

Hartmann made the remarks at a stakeholders’ forum in Ibadan, Oyo State, marking the conclusion of the CFC-funded Cassava Value Chain Project in Nigeria. The project was implemented by IITA together with its national partners.
