Biomass pellet fuel, resembling a thick pencil, has a cylindrical shape and measures about two to three centimeters in length. At first glance, it might look like animal feed, but this is not for livestock—it’s for boilers. These pellets are a form of biomass fuel, and more and more companies are adopting them as part of their efforts to meet environmental standards and boost economic efficiency. Industries such as textiles, food processing, and chemicals are increasingly turning to clean energy alternatives, driving a low-carbon transformation.
One popular raw material for these pellets is the abandoned palm shell. Companies like Shishi Yongning have invested over 300,000 yuan to replace traditional coal-fired boilers with a "chain biomass boiler." Similarly, Land Group in Shishi spent between 50,000 and 60,000 yuan per boiler, switching from coal to palm shells. Palm shells, once considered waste, are now recognized as an eco-friendly fuel. Originally used in Malaysia since 2005, they’ve gained popularity in Europe and are now being imported into China, particularly from Indonesia.
After drying, palm shells can be burned directly without additional processing. Their heat value ranges between 4,600 to 5,000 kcal/kg, which is higher than many other biofuels. According to officials at Quanzhou Entry-Exit Inspection and Quarantine Bureau, local enterprises are now importing palm shells from Fujian ports, with demand expected to grow rapidly.
The benefits of biomass fuels are clear. As cities push for cleaner environments, coal is being phased out in favor of alternatives like biomass, electricity, diesel, or natural gas. According to Wang Zhenquan, general manager of Quanzhou Hengxing Energy, biomass offers greater economic returns. For example, a four-ton oil-fired boiler requires 88kg of heavy oil per ton of steam, costing around 418 yuan. Switching to biomass can save up to 40%, leading to annual savings of 2.4 million yuan for a company consuming 500,000 yuan in fuel monthly.
In addition to cost savings, biomass fuels significantly reduce pollution. Companies that previously dealt with coal dust and ash now enjoy cleaner boiler rooms. Replacing 10,000 tons of coal with palm shells annually can cut COâ‚‚ emissions by 161,000 tons, along with 150 tons of soot, 80 tons of sulfur dioxide, and 70 tons of nitrogen oxides.
Despite its advantages, biomass fuel still faces challenges. While it is more expensive than coal—costing about 20% more—its high calorific value and purity make it economically viable in the long run. It also reduces labor needs, with one worker now sufficient instead of four. Palm shells, in particular, are cost-effective, priced at $80 per ton, 10–15% cheaper than bituminous coal. Using them can save 1,200 tons of standard coal annually and qualify companies for government awards of 300,000 to 500,000 yuan.
To secure supply, companies like Hengxing Energy have established dozens of acquisition points in Southeast Asia. However, supply still lags behind demand, limiting the widespread adoption of this green fuel. Despite this, the trend shows no signs of slowing down.
