In my district, a “green change” around the bottom of bamboo is continuing in the mountains. Past piles of mountain, unsuspected crumbs and sawdusts have now become, through technological empowerment, high-quality mechanisms, not only to leave the local environment “silent face”, but also to move out of the country to sell many countries and regions, such as europe, america and south-east asia, to become “black gold” for rural revitalization。
From “waste” to “black gold”
Into the mackerel processing area of the port town, the air was frazzled, the roads were clean and clean, and there was no sign of past dust. In the production workshop of the local lead company, kim kai bioenergy ltd., jiangxi province, the machinery is booming and the production line is working. A carload of bamboo underlays is carried with “eat” and, following multi-track processes such as shredding, drying, rod making and carbide, a box of black-haired charcoal is released。
“these crumbs used to be a burden on businesses, and it was hard to buy them away; they are now precious.” the general manager of kim kai, wu mei ming, standing by the production line, grabbed a sawdust and calculated a fine “ecological bill” for the press. “we bought about 140 tons of sawdust from the surrounding eight bamboo processing companies each day at around $380 a ton. In one case alone, more than 40,000 tons of local bamboo waste can be consumed each year, overcoming the environmental challenges that have plagued businesses for many years.”
However, wu mei ming's “green magic” is much more than that. He described the large quantities of flammable gases that companies produced in the production of mechanism carbon. The direct emissions of these gases in the past were both wasteful and polluting. Today, firms have invested in the construction of gas collection systems to recycle the flammable gases for use in boilers, and the resulting vapour is sold to nearby bamboo processing firms at prices below market prices. This model has been operating steadily for almost four years since its launch in july 2022. He said, “this is a chain that takes resources `drying' clean. We'll make an extra $1. 8 million a year for steam alone."
Up and down, hold hands: a win-win account
This pattern of closed circulation of sawdust-chard-stealing allows upstream and downstream firms to achieve real efficiency gains and mutual benefits. Jiangxi jin jing industries ltd., located not far from kim kai, is a mackerel and mackerel processing enterprise. In the company's busy workshop, the chief of staff, zeng ling, showed journalists a comparison of past and current costs. “it used to cost $50 per ton to process the ton for transport, and now, on the other hand, it is $380 per ton to sell to kim kai. This one makes $430 net per ton of bamboo crumb.” “more importantly, our company used to provide the heat needed to dry its own boilers, not only by burning large amounts of bamboo crumbs each year, but also by paying for electricity, water, maintenance of dust removal equipment and salaries of two boilers. Now we're using all the steam from kim kai, we've stopped our boilers and there are no more smoke and safety in the workshop. The combined costs of fuel, labour and maintenance of equipment are calculated to be approximately $500,000 per year.”
Full bamboo utilization: a bamboo “dry and clean”
My county has over 500,000 acres of bamboo wood. In the past, bamboo processing was concentrated mainly on primary products such as bamboo chopsticks and bamboo floors, with a large number of bamboo crumbs, mackerel and bamboo branches being discarded or burned as waste, wasteing resources and polluting the environment。
In recent years, my county has promoted the transformation of the bamboo industry, led by the concept of circular economy. At present, more than 40 bamboo processing enterprises have been developed throughout the county, starting with a complete “take-all” industrial chain, ranging from bamboo food, bamboo chopsticks, bamboo floors to active charcoal and mechanism charcoal. The entire county consumes more than 150,000 tons of bamboo resources each year, and the bamboo industry produces more than 730 million yuan a year, leading to the employment of thousands of local farmers at home。
At the end of the chain, the mechanism became the “black horse” of export earnings. This green energy product, which is based on bamboo crumbs, has high density, high combustion value, long combustion time and environmentally clean quality and is highly favoured by international markets. Today, my county's mechanisms are not just lukewarm in the domestic market, but also cut across the oceans and far from europe and the united states, the middle east and south-east asia。
Green development: crumbs for the future
From the “environmental burden” of the past to the “green wealth” of today, the luxurious turn of my county has been a microcosm of the dynamic practice of the concept of circular economy at the grass-roots level。
“a mackerel, which, after thorough processing, is made of chopsticks and floors; bamboo crumbs is made of charcoal; steam is supplied to the factory; and the remaining small amount of ash slag can be recovered as potassium fertilizer.” "our goal is to make every piece of bamboo's `dry and quench' as valuable as possible."
In the next step, the county officials said that the drums would continue to improve the chain of bamboo industries, support enterprises in technological innovation, promote the high-end, branding and internationalization of the charcoal industry, and make the bamboo sea a truly revitalized “green bank”。
A pile of useless little bamboo crumbs has now become, with the impetus of the circular economy, a green product with high value added and new dynamics driving sustainable development. In copper drums, green water and green mountains are being transformed into gold mountains。
