Biochar: Biomass Charcoal for Soil improvement

Biochar, a powerfully circular way to fight climate change

Biochar technology is a form of charcoal. It is made through a process called pyrolysis which involves burning of biomass in an oven with little or no oxygen. What you get out of it is solid material which then is added into soil. Under the right circumstances, biochar provides a unique opportunity to sequester carbon and improve soil quality by using locally sourced resources, and even a single application can provide benefits for years

Problem

Poor soil fertility and health
High greenhouse gas emissions from agricultural practices
Low crop yields and agricultural productivity
Ineffective management of agricultural waste
Dependence on traditional, environmentally harmful fertilizers
Soil erosion and nutrient leaching
Unsustainable land use practices
Limited contributions to climate change mitigation efforts

Solution

Turning agricultural residues into biochar reduces the need for farmers to burn residues, while also creating a valuable soil amendment that can improve soil, reduce water usage, lower methane emissions, and save on input costs for expensive and polluting chemical fertilizers. Biochar fertilizer can:

Reduce the money you spend on NPK fertilizer when used on the long run;
Reduce the money you spend on pesticides;
Increase your crop yields;
Improve your soil; and
Increase your soil’s ability to hold water.
Moderate your soil acidity
Increase water retention
Increase number of beneficial soil microbes

Key points to design your business plan

Manufacturers

Producing Biochar technology offers an eco-friendly and sustainable solution to improve soil fertility, increase crop yields, and sequester carbon, benefiting farmers and contributing to environmental health globally.

To efficiently produce Biochar, it is essential to:

Identify source reliable suppliers for production equipment, which costs around 305 USD and is available in Nigeria (Kano State: +2347066787854). Small-scale systems processing 500 kg/hr). This facility could produce several tons of Biochar annually, generating significant revenue.

Your potential customers include farmers, agricultural cooperatives, development projects, government agencies, and NGOs focused on sustainable agriculture.

Establishing strong partnerships with distribution networks and agricultural stakeholders is crucial for the success of your business.

Users

Using Biochar is a cost-effective and sustainable farming practice that enhances crop yields, improves soil health, and reduces dependence on synthetic fertilizers.

To successfully implement this technology, you will need:

Reliable suppliers for Biochar and possibly equipment for on-site production. For optimal results, farmers need 5 to 10 tons of Biochar per hectare.
About the cost structure, you need to find cost of biochar per ton which is available in Nigeria (Nigeria; +234806755265).

Estimating the profit margin based on Biochar's impact on yield and input costs will be essential for maximizing economic benefits.

Your main partners is biochar manufacturers.

The United Nations Sustainable Development Goals that are applicable to this technology.

Goal 1: no poverty

Goal 3: good health and well-being

Goal 13: climate action

Goal 15: life on land

For more effectiveness and rapid activation,

Mix biochar with organic manure or compost and incorporate it into the soil during land preparation.
Frequency of application: Due to its gradual process in decomposing in soil, single applications of biochar can provide beneficial effects over several growing seasons in the field.
Therefore, biochar does not need to be applied with each crop, as is usually the case for manures, compost, and synthetic fertilizers.

Biochar is great stuff but it can be dangerous to you and your crops. Therefore, Keep your biochar wet – the tiny particles can get in your lungs and cause cancer
Never put biochar in your soil immediately after making it.

Biochar is very powerful if you use too much you risk:
• Locking up the nitrogen in your soil
• Locking up any chemical fertilizers you are using
• Locking up any pesticides and herbicides you are using

Materials and Equipment

Drum
Duct tube
Ignition cone
Feed stalk (e.g., rice husk, wood, shavings or other crop residues)
Ignition material
Water
Nylon/leather
Rope

Rice Husk Biochar Production Procedure

Feed the ignition material into the ignition cone
Insert the cone into the drum
Fill the drum with the feed stalk
Ignite the material inside the cone
Insert the duct tube into the ignition cone and confirm the smoke is escaping through the pipe
After 3-4 hrs stir the rice husk with the formed biochar
Fill the drum with the rice husk to the brim
After 1-2 hrs wet the duct tube with water and remove
Shut the air/oxygen by covering the drum with leather
Leave it in this condition until the next day
The biochar is ready to be activated with compost or compost tea
