Biochar - Terra Preta

Turn excess biomass into valuable soil conditioner
Create prosperity, food security and fix carbon for 2000 years

Unbelievable - even from weed like water hyacinth and water fern...

You have wood waste from pruning?
Avocados, fruit trees, cocoa,
You have wood waste from replanting Palm oil?
You should consider CARBONIZATION!

Everyone knows char coal. This is carbonized wood. It is used for barbecue, cooking, water filtration, medicine and more.

Most of the charcoal in developing countries is produced in the old inefficient style with only 20% or less efficiency.

A new use is biochar as soil enhancer.

This technology is thousands of years old and rediscovered a few decades ago. Therefore, still widely unknown.

Have you thought about increasing your farm yields by biochar from your own waste?

Biochar has a very porous structure. So, it can hold nutrients and water.

Biochar making is very time intensive in the old style or very expensive in industrial style.

SLP developed a Semi-Industrial Carbon Box to

  • reduce CAPEX to 3-5% of the industrial systems
  • increase the carbon efficiency up to 40%
  • reduce OPEX to labour cost only

We operate our C-Box in Batch mode.

No motors.

No electrical connection

Once the carbonization is started, it runs autonomous.

The process stops by itself after complete carbonization.
