Making biomass charcoal briquettes , with considerable profits

Charcoal has a wide range of uses. A large amount of charcoal is needed in industry to make iron smelting reducing agents, adsorbents, carbon disulfide, activated carbon, etc. In daily life, charcoal is often used for hot pot, barbecue, heating, etc. The traditional method of burning charcoal consumes a lot of wood resources, which is not conducive to sustainable development strategies.

In order to ease the contradiction between supply and demand, a machine-made charcoal (biomass charcoal) briquettes with sawdust, wood chips, cotton stalks, coffee shells, coconut shells, sorghum stalks, corn stalks, corn cobs, wheat straw, rice husks, bean shells, peanut shells, bamboo residues, sugarcane residues, papermaking waste residues, etc. as raw materials was born.

Compared with traditional charcoal, biomass charcoal has the following advantages:

• Regular and uniform shape, controllable size and length.
• No charcoal head, no smoke, no sparks, no odor.
• Dense structure, burning time is 3~4 times that of traditional charcoal.
• The calorific value is as high as 2926~3344 MJ/kg, which is 1.5 times that of traditional charcoal.
• Raw materials are available everywhere, with low cost and high profit.
• Fast production speed.

Open a charcoal processing factory for family

1. Investment budget

• 1. The area of the house is 50-100 square meters, and raw material and finished product warehouses are also required. In the early stage of the factory, old factory buildings can be used or idle houses can be rented or simple factory buildings can be built.
• 2. A small-scale machine-made charcoal factory with an annual output of 200-300 tons can be opened. The investment in a full set of equipment (1 sawdust crusher, 1 dryer, 1 molding machine, and 1 carbonization machine) is about 15,000 US dollars.
• 3. Prepare working capital of 5,000 US dollars to purchase raw materials and pay the initial wages of workers. If there are ready-made sawdust, shavings, wood chips, peanut shells, rice husks, cotton stalks and other waste materials, working capital can be reduced.

2. Production process

The production process of biomass charcoal briquettes:

Raw material crushing → drying → briquettes → carbonization → cooling → packaging.

3. Benefit analysis

The level of profit is related to many factors such as production cost, management level, output and quality of machine-made charcoal, market price and tax, among which the quality and production cost of machine-made charcoal have the most obvious impact on profit. The following is an explanation of the profit comparison of high, medium and low temperature charcoal.

• 1. Low temperature charcoal (charcoal for industrial and agricultural production, charcoal for heating, charcoal for hot pot). Its carbonization temperature is low, the yield rate is about 80%, and the quality is slightly poor. The total cost is about US$200/ton, the ex-factory price is about US$800/ton, the profit per ton is about US$600, and the minimum is US$400.
• 2. Medium temperature charcoal (charcoal for hot pot and barbecue). The carbonization temperature is moderate, the yield rate is about 75%, and the quality is moderate. The total cost is about US$500/ton, the ex-factory price is about US$1,000/ton, and the profit per ton is about US$500, and the minimum is US$400.
• 3. High-temperature high-quality charcoal (charcoal for barbecue and export). The carbonization temperature is high, the finished product rate is about 60%, the quality is excellent, and it can be used for export. The total cost is about 800 US dollars/ton, the bid is about 1400 US dollars/ton, and the net profit per ton is 600 US dollars.

From the above analysis, it can be seen that investing in machine-made charcoal (biomass charcoal) has considerable profits
