Supporting innovative solutions for land management issues and identify carbon removal opportunities.

Rice husk to premium biochar project

Mekong Delta, Vietnam


Project Overview

Biocare has partnered with the Australian Department of Foreign Affairs and Trade, leading universities in Australia and Vietnam and a Vietnamese biochar operator to create a landmark biochar project in the Mekong Delta.

This region produces more than 80% of Vietnam’s rice harvest with significant biomass waste that is traditionally burned in the open air or left to decompose.

Feed stock

The project feedstock consists of the collected rice husk residues from nearby rice farms and mills.


Biocare is providing a bespoke high efficiency pyrolysis continuous reactor to meet carbon registry standards.

Biomass and carbon removal potential

With over 80% of Vietnam's rice harvest originating from the Mekong Delta, this initiative addresses the prevalent issue of burning or neglecting agricultural waste, which contributes to significant methane and CO2 emissions. The transformation of this waste biomass into biochar not only represents a robust carbon storage solution but also enhances soil quality by improving water and nutrient retention and mitigates soil acidification and nitrate leaching.

Project Carbon Removal Approach

Baseline scenario

Combustion into rice husk ash

​​Project scenario

Biochar Production

Rice husks are abundant in the 

Mekong Delta. Huge amounts of rice husks are combusted in boilers to dry rice paddy and the resulting ash is often sold for low prices, dumped into waterways, or even some mills pay for its removal. The rice husk is often combusted in an uncontrolled manner producing crystalline silica ash, which has a low value and is also carcinogenic and a health hazard..

Opportunity to convert the wood

into biochar to upcycle waste and generate CDRs*.

Biochar will safely sequester carbon for hundreds of years in addition to delivering numerous co-benefits.
