Practical Benefits of Biochar

5 mins 53 secs

Key learning objectives:

  • Identify the disadvantages of incinerating rice husks

  • Outline the benefits of biochar

  • Understand how biochar can create a circular economy

Overview:

Many rice mills sell their rice husk to power plants to incinerate for power and heat. This is economically efficient but bad for the environment, as it releases carbon into the atmosphere and creates a hazardous environment for soils. Biochar provides long-term carbon storage, increases agricultural yields, enhances soils and increases water retention.

Summary
What are the disadvantages of incinerating rice husks?

In the Philippines, most smaller rice mills sell their rice husk to power plants, which incinerate the rice husk to generate power or heat. This is economically efficient but has two major disadvantages. 

1. Fully burning the rice husk releases all of the carbon back into the atmosphere 
2. Generation and disposal of rice ash damages the soil and is a hazardous waste

What are the benefits of biochar? 

1. Increased agricultural yields. Alcom farm trials have shown that after one application of biochar there was a 15-20% increase in paddy and onion yields, relative to the control plot of land. 

2. Soil Enhancement. Biochar improves nutrient and water retention, promotes microbial development and increases the pH of acidic soils. It is especially valuable in degraded agricultural soils.

3. Water Retention. Biochar intercepts nutrients, thereby reducing nutrient leaching into water bodies. It reduces the amount of freshwater required to irrigate crops, indirectly making the soil more drought resilient.  

How can biochar create a circular economy? 
Alcom provides rice mills with electricity and is also marketing the biochar to rice farmers. The rice husk is pyrolyzed into biochar, which is sold to local farmers. The biochar increases agricultural yields, which generates more rice and rice husk, creating a small circular economy.
