Disposal of Durian Shells | Can Durian Shells Be Processed into Biochar

Durian is known as the “King of Fruits”, favored worldwide for its unique flavor and high nutritional value.

While people enjoy delicious durian, large amounts of waste durian shells are often ignored.

Traditionally, durian shells are regarded as useless garbage.

Random disposal causes environmental pollution and serious resource waste.

In fact, durian shell is a high-quality biomass raw material and can be fully processed into biochar.

Durian shell features hard texture and unique fibrous structure.

It is rich in cellulose, hemicellulose and lignin, which are essential components for biomass carbonization and energy production.

Dry the raw durian shells first to reduce moisture content.

It effectively improves carbonization efficiency and ensures stable finished charcoal quality.

Crush the dried durian shells into uniform particle size.

Proper particle size makes feeding and furnace carbonization smoother.

Put crushed durian shell materials into the carbonization furnace.

Under oxygen-free or micro-oxygen environment, heat the material at 300℃–600℃ for thermal pyrolysis.

The biomass raw material is fully decomposed and converted into solid biochar.

After carbonization is completed, cool the high-temperature biochar down to room temperature.

Pack the finished products in standard specifications for convenient storage and transportation.

Durian shell biochar has excellent adsorption performance, high calorific value and stable chemical properties.

It is widely used in multiple fields:

Durian shell recycling conforms to environmental protection rules and sustainable development concepts.

It turns waste fruit shell into valuable reusable resources, bringing both environmental benefits and considerable economic profits.
