Cassava starch processing

The cassava starch industry in Vietnam comprises approximately 120 industrial-scale processing factories across 27 provinces and cities. These factories have a combined design capacity of 11.3 million tons of fresh tubers per year, with an actual production capacity of 8.62 million tons annually. Cassava starch has diverse applications, including food, pharmaceuticals, cosmetics, and confectionery. Modified cassava starch serves as a primary raw material for eco-friendly biofuels, addressing global fuel demand. Cassava starch production in Vietnam can be categorized into small-scale (70-74%), medium-scale (16-20%), and large-scale (about 10%) operations, with large-scale facilities utilizing advanced technology and imported equipment for higher efficiency and quality.

Cassava processing and application

Cassava starch finds applications across various industries, including food, confectionery, sweeteners, adhesives, plywood, textiles, paper, biodegradable packaging, monosodium glutamate (MSG), excipients, livestock feed, and alcohol production. Cassava chips serve as an alternative raw material for ethanol production. Cassava tubers can be processed into chips and pellets for animal feed, and cassava leaves are used as livestock fodder. In the food industry, cassava and its derivatives are employed for thickening, texturing, and stabilizing various products. Cassava starch is also utilized in the production of glue, biodegradable packaging, paper, and textiles, enhancing product properties and performance.

Native cassava starch processing

Cassava starch processing methods include manual processing, semi-mechanized processing, and modern processing. In manual processing, cassava tubers undergo washing, hand-peeling, scraping, and drying. Semi-mechanized processing involves manual peeling and electric motor-driven grinding with added water, followed by filtration and sedimentation. Modern processing prioritizes quality and efficiency, utilizing advanced technology for stages from receiving tubers to drying, with an emphasis on minimizing oxidation.

Innovation/Modern technology

Vietnam faces challenges in its energy security due to declining domestic oil reserves and increasing oil imports, projected to reach 50-60% by 2050. To address this, the country is exploring alternative energy sources, with biofuels emerging as a key option. The government recognizes the economic strain caused by fossil fuel dependence and aims to reduce reliance on imported petroleum through domestic biofuel production. They have set ambitious targets, aiming for a 21% biofuels share by 2015 and 100% by 2050. However, barriers include the lack of a comprehensive policy framework to support bioethanol, issues with supply chain management, technology access, and upfront investment requirements. Complex institutional arrangements also pose challenges. Innovations like the High Gravity fermentation process and viscosity reduction enzymes offer potential solutions to improve ethanol production efficiency.

Strategies for knowledge and technology

Strategies for knowledge and technology transfer include organizing local training, translating materials into the local language, establishing national cassava organizations, and creating local networks within the cassava value chain. In conclusion, Vietnam's cassava starch industry has grown substantially, but it faces challenges and opportunities, particularly in the realm of biofuels. Government policies, technology innovations, and efficient supply chains will be critical to its continued development and sustainability.

SWOT Analysis

Strengths in Vietnam's biofuel industry include rapid cassava production growth, government policies since 2003 supporting energy efficiency and biofuel development, and ongoing development projects. Weaknesses encompass plant shutdowns, technology barriers, and a lack of qualified workers. Opportunities arise from increased government attention to biofuel production, while threats include pollution in processing and market price fluctuations.
