Suichang is a resource-rich county. Suichang Bamboo Charcoal has been named as “Hometown of Bamboo Charcoal in China” by China Economic Forest Association for its unique advantages. The history of burning charcoal in Suichang County has a long history. In the Northern Song Dynasty and the Liao Dynasty, there was a custom of building a kiln to burn charcoal. According to the records of Suichang County, “When the Song Dynasty was in the Northern Song Dynasty and the Liao Dynasty (581-1127), the Suichang people opened up the original forest land in the central and southern basins of the county. In this production process, there was a In the 1980s, according to the needs of the international market, Suichang was the first in the country to burn white charcoal (Ugangang charcoal) to Japan, and the white charcoal was compact. It is popular in Japan with a large-scale and long-burning time. The annual export volume reached 3 million US dollars. A number of export charcoal producers have burned white charcoal. In a few short years, Suichang bamboo charcoal industry has developed rapidly. By the end of 2003, the number, scale, output value and depth and breadth of product development of Suichang Bamboo Charcoal Industry have been among the highest in the country, becoming the largest bamboo charcoal production, processing and export base in China, and a veritable “Hometown of Chinese Bamboo Charcoal”. . In order to better protect the environment and natural forest resources, in 1995, the State Forestry Administration ordered a total ban on the cutting of broad-leaved forests. Zhejiang Province gradually banned the burning of natural broad-leaved forest charcoal from 1996, and completely banned charcoal shipments in 1999. . Suichang County began to burn white charcoal in 1996, and the original charcoal production enterprises faced bankruptcy or bankruptcy. Some charcoal merchants who were originally engaged in the export of white charcoal learned that Japan is developing information on bamboo charcoal products. They immediately invested nearly one million yuan and devoted themselves to researching the firing method of bamboo charcoal. After hard work, they first developed a suitable domestic product in Japan. The bamboo charcoal series products demanded by the Korean market have since been born in Suichang and have been flourishing. Suichang Bamboo Charcoal started in the mid-1990s and formed a certain scale in the late 1990s. Under the active guidance and strong promotion of the county party committee and county government, Suichang became the country's largest bamboo charcoal production base in 2003. At the end of 2007, there were 53 bamboo charcoal production and management enterprises registered in Suichang County, employing more than 3,000 people, including 1 provincial leading enterprise, 3 municipal leading enterprises, and 4 enterprises with self-operated export rights. The company has passed ISO9001-2000 quality management system certification, two companies have passed ISO14000 environmental management system certification, and many companies have passed CNAB-S12:2003 organic product quality certification; many products have obtained county, city, provincial and national levels. Honorary title. It has developed more than 200 kinds of bamboo charcoal and bamboo vinegar products, and has 22 patents for bamboo charcoal production, including 2 invention patents and 20 new utility patents. Bamboo charcoal products have realized the original bamboo charcoal refining and tissue charcoal export. The single extensive operation has transformed into a comprehensive modern technology-based enterprise such as bamboo charcoal processing, bamboo vinegar refining, product development and testing, and developed the original charcoal series, daily health care series, humidity control and deodorization series, washing products series, craft jewelry series, Seven series of bamboo charcoal fiber series and bamboo vinegar series. In addition to being exported to Japan, South Korea, Europe, America and Southeast Asia, the domestic market has been expanded in recent years. More than 2,000 chain franchisees have been established in China. Bamboo charcoal enterprises have established more than 3,000 sales agents in major cities across the country, occupying domestic One-third of the market share. Up to now, Suichang has owned three regional brands: “China Bamboo Charcoal Township”, “China Bamboo Charcoal Industrial Base” and “Suichang Bamboo Charcoal” National Geographical Indication Products. The bamboo charcoal industry has become a major emerging industry in Suichang.
