BiGchar Technology

BIG’s patented fast rotary hearth technology was developed to satisfy a need for cost effective conversion of waste biomass to charcoal products. The key features of our technology are:


BiGchar units go to the biomass

BiGchar technology was developed to be mobile for one very good reason: namely, to overcome the fact that it is typically too expensive to collect and transport biomass for  commercial production of char. BiGchar mobile units process at the source. The resulting BiGchar product is reduced in volume by as much as 20 fold, making it much more economical to transport to the end user.


High throughput

The BiGchar 2200 is designed to continuously process in excess of 1 tonne per hour of biomass. Most conventional charcoal processes rely on batch methods with throughputs measured in tonnes per day rather than tonnes per hour.

BiG can supply larger units, with increased cost efficiency, but they may compromise mobility. Also smaller units can be supplied, but they may compromise cost efficiency.

The BiGchar 2200 has been designed to have unrestricted mobility on public roads, while offering adequate throughput for cost efficiency..


Low production cost

We believe the BiGchar technology is the lowest cost charcoal process available in Australia that will produce at a commercially viable throughput while meeting current environmental and industrial safety standards.


Flexible site and operational requirements

Mounted on a suitable truck or trailer, the BiGchar 2200 has a foot print of approximately 4 metres long by 2.4 metres wide and a height of 3.5 metres (excluding the exhaust flue).

Using its manual jacking legs, the BiGchar 2200 can stand on its own feet to free its transport vehicle for other duties. The 2200 is suitable to operate on vehicle, off vehicle or within a customised container.

In mobile form the BiGchar 2200 is intended to require a single operator, with a second person required only to assist with unpacking/packing the unit and to relieve the operator for breaks. In fixed site form the BiGchar unit can be configured for largely unattended operation.


Flexible feed requirements

BiGchar units can accept a wide variety of feed materials, including sugar cane trash and other crop waste, chipped green waste, sawdust, poultry litter and animal manure.

BiGchar units will also handle feed moistures up to 25% before external drying is recommended. Moistures up to 50% can be handled, at reduced production rate. BiG can provide external dryers that use the energy from the process off-gases.
