The nut shell charcoal making machine solves the challenge of nut shell waste disposal while converting it into high-value-added products. It serves as a key link between the nut processing industry and the environmentally friendly energy industry. Nut shells (walnut shells, almond shells, peanuts, macadamia shells, and coconut shells) are excellent raw materials for producing high-quality biochar due to their high hardness and lignin content.
The charcoal making machine heats nut shells under oxygen-deficient or anaerobic conditions, causing them to undergo thermochemical decomposition. Ultimately, the nut shells are converted into biochar, tar, and syngas.
A large peanut processing company in Henan, China, introduced a MJT-2000 peanut shell carbonization equipment in 2023 and quickly turned a profit after commissioning.
This company processes 100,000 tons of peanuts annually, generating approximately 30,000 tons of peanut shell waste. Previously, the company disposed of the peanut shells using a combination of open-air incineration and landfilling. Not only did this cost them annual landfill site rental fees, but they were also repeatedly penalized by environmental protection authorities for pollution from incineration, threatening production suspension.
The nut shell charcoal making machine operates in a fully enclosed process, and the accompanying exhaust gas purification system treats exhaust gases to below emission standards. The peanut shell charcoal production process is smoke-free and odorless, completely eliminating the risk of environmental penalties.
The peanut shell charcoal produced by the biomass carbonization plant provides a low-cost soil improvement material for local agriculture.
Mingjie biomass carbonization plant is not only used for nutshell carbon production, but also for various organic solid waste pyrolysis treatment, such as sludge, animal manure, agricultural waste, forestry waste, etc.
Waste Utilization, Turning Waste into Treasure
The nut shell charcoal making machine converts agricultural waste into high-value products, reduces environmental pollution. After pyrolysis carbonization, nutshells reduce their volume by over 70% and their weight by 50%-60%.
Nutshell charcoal can be used in soil improvement, water purification, electrode materials, and other fields. Combustible gas can directly power the bio charcoal production equipment. Tar can be refined into chemical raw materials such as phenols and aromatics.
Carbon Negative Technology
The entire nut shell charcoal making process stabilizes atmospheric carbon dioxide, contributing to mitigating the greenhouse effect. The oxygen-free pyrolysis process eliminates harmful gases (dioxins and sulfur dioxide) produced by incineration. The nut shell carbonization process also kills insect eggs and pathogens that may be present in the nutshells.
High Product Value
The hardness and pore structure of nutshell charcoal are particularly suitable for producing high-grade activated carbon, offering significant economic benefits.
Achieving a Circular Economy
The payback period for nut shell charcoal making machine is only 2-3 years, providing a sustainable solution for agriculture and industry.
