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 consuming in the old style or very expensive in industrial style.

SLP is going to develop 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 will 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.

The 6 success factors for biogas projects – now in UNIDO’s new publication

UNIDO (United Nation Industrial Development Organization) has accompanied and support numerous biogas, biomass and biofuel projects in the past worldwide. To compile and share experience, UNIDO held an Expert Group Meeting on biomass with participants from various countries and backgrounds to discuss the lessons learnt for successful biomass projects.

Katharina Danner was invited as resource person for biogas, giving her expertise on international biogas projects to the participants.

The 3 biggest benefits with straw digestion

Benefit 1: Up to 50 % less nutrients at the same biogas quantitiy makes it easier to match with the fertiliser ordinance.

Benefit 2: No new final storage necessary because straw contains only little water. Separation even pulls water out of the system.

Benefit 3: Straw has a calculable price because no animal wants to have it will.
