Great news for the environment

At the beginning of November, the Chinese National Development and Reform Commission announced an ambitious plan to replace plastics with bamboo. According to the plan, by the end of 2025, the infrastructure should be in place to gradually replace plastics with renewable materials wherever it is technically feasible and economically viable. The Hunan province, known for its cultivation of fast-growing woody grasses, has become the center of this program. By 2028, the value of its bamboo production is expected to exceed 100 billion yuan annually.

Bamboo instead of plastic

The Hunan province was chosen as the pilot region for the national project. This was not by chance. With over 1.2 million hectares of bamboo plantations, which thrive in the local humid subtropical climate, it is the third largest supplier of this commodity in China. At the same time, it has a dense network of processing companies and manufacturing clusters. Therefore, it was chosen as a promising "laboratory" for the national innovation program.

In the land of giant grasses

Eight teams from local universities are working on the project under the umbrella of a newly established Bamboo Industry Research Institute, which is directly linked to the corporate sector. This sector is represented by more than 4,000 processing companies, which together form a complex industrial chain. The total value of bamboo production in the province last year reached 54 billion yuan. This inland province, with a population of 66 million, holds a dominant position in a number of product categories. For example, half of the disposable cutlery sold in China comes from Hunan.

The benefits of the Bambusoidea subfamily

“Bamboo grows quickly, has a short maturation cycle, high strength, toughness, and hardness. It is naturally renewable, recyclable, and biodegradable,” says Wu Yiqiang from the Central South University of Forestry and Technology, listing the benefits of the plant, which can reach a height of up to 40 meters. According to him, the plant has enormous potential for reducing the burden on the environment and the carbon footprint.

However, bamboo products are not only "carbon neutral": the plant absorbs CO2 from the atmosphere, which gives it a unique advantage in replacing plastic products and reducing plastic pollution. "Globally, 430 million tons of plastic products are produced annually. However, with the development of technology, the areas of bamboo use are constantly expanding. This will allow us to significantly reduce plastic consumption," adds Wu Yiqiang.

Bamboo plastic pallets

The program is based on two pillars: substituting plastic products with bamboo products (e.g., artificial textile with bamboo fiber products) and developing plant materials for further processing. Engineers at New Material Technology Co. Ltd., located in the economic zone in Taojiang County, have developed a technology for processing bamboo waste into a moldable material that is highly strong and durable when hardened. Xianlian Tianxia Company uses this material to produce pallets for logistics. "Our pallets are half the price of plastic ones. At the same time, they show better results in durability tests," explains Huang Dai from Xianlian Tianxia. According to him, the superior properties of the raw material are due to the higher strength of the bamboo fibers. In seven months, the company sold bamboo pallets for 26 million yuan.

From clothing to construction: The range of products is very broad. Companies in Taojiang, Suining, and other cities supply underwear, home textiles, tableware, toys, furniture, and also building materials. Their products are increasingly being purchased by foreign partners. A competitive advantage for Hunan companies is the low tariffs. Many countries are imposing higher import duties on products with a significant carbon footprint, including plastic products. Specifically, the European Union plans to impose a 26% tariff on imports of plastic products. Challenge: High price Overcoming the obstacles to implementing the "bamboo instead of plastic" concept in practice requires a great deal of effort. Despite the obvious advantages of natural materials in everyday life, plastic remains dominant, which is reflected in its market share. The main reason is the high price of the renewable raw material. For example, kindergartens are aware that natural bamboo toys are environmentally friendly and completely safe (non-toxic), but they hesitate to purchase them due to their higher price. Similarly, the food service sector is still resistant to the wider adoption of natural tableware: disposable plastic tableware is cheaper. Innovation will change the situation The relatively high cost of the plant-based raw material is mainly due to the still high proportion of manual labor involved in its processing. Bamboo is mostly harvested by hand, and its transportation from high-altitude plantations using special cable cars is challenging. A ton of fresh Hunan bamboo costs an average of 500 yuan, with the cost of harvesting exceeding 350 yuan. The situation is expected to change with the introduction of modern harvesting machines, which engineers are developing with the primary goal of minimizing human labor. Another factor is reducing logistics costs through investments in transportation infrastructure. However, the most important role will be played by applied research and the companies themselves: innovations in materials and processing methods can help bamboo overcome plastic. This is already happening in the production of pallets. Therefore, the government program includes massive support for participating companies and research institutions. Ivan Černý, Photo archive.
