With the innovation of carbonization technology, the boundaries of carbonization machine raw materials are extending from traditional agricultural and forestry waste to a wider field. Urban greening prunings, a long-neglected resource, show amazing potential through graded processing: fine branches and leaves with a diameter of less than 2 cm can be made into ecological filter materials with a porosity of 75% after low-temperature carbonization for rainwater purification systems; thick dry branches are suitable for high-temperature treatment and converted into high-calorific value barbecue charcoal. The establishment of a cooperation model with municipal departments enables enterprises to obtain raw materials at a negative price (processing subsidies), achieving dual benefits of environmental protection and economy.

Even more disruptive is the development of marine biomass: salt-containing biomass such as seaweed and mangrove litter, after being treated with patented dechlorination technology, its carbonization products have emerged in the field of fuel cell catalysts. Laboratory data show that the conductivity of seaweed charcoal is 2-3 orders of magnitude higher than that of traditional bamboo charcoal, which provides a possibility for machine-made charcoal to enter the new energy track. The innovative application of agricultural processing waste such as coffee shells and cocoa pods has opened up the market for specialty carbons. After controlled oxygen carbonization at a specific temperature range, the unique aromatic substances of the raw materials can be retained, making them the preferred materials for high-end water treatment and food-grade activated carbon.

These breakthroughs not only expand the raw material map, but also give birth to a new value dimension. When the machine-made carbon industry breaks away from the traditional positioning of "fuel supplier" and turns to environmentally friendly materials, industrial catalysis, new energy and other fields, its market space is leaping from tens of billions to hundreds of billions. This industrial revolution triggered by raw material innovation will redefine the future of biomass carbonization.
