Containerized Unit to Transform Biomass Waste to Heat and Biochar

The ALL Power Labs CharTainer is a compact, high-volume, Combined Heat and Biochar (CHAB) pyrolizer system enclosed within a standard 20-foot shipping container. The system is fully automated and complete – from biomass hopper, gasifier-retort, and clean-burning flare with heat exchangers to biochar takeoff – all integrated within the shipping container envelope. The CharTainer uses a scaled-up version of APL’s newest Swirl Hearth architecture previously refined and proven in our PT150 PowerTainer.  The swirl hearth architecture includes technology innovation that widens the range of acceptable feedstock and ensures the quality of biochar produced.

The CharTainer is being developed to meet the ever-increasing demands for localized biomass waste disposal as well as high-quality, high-temperature, electrically active biochar in the agronomy and climate/carbon mitigation sectors. Partnering with our carbon-drawdown initiative, The Local Carbon Network, APL’s engineers have been working with biologists, agronomists, farmers, and climate researchers to perfect biochar-retort technology and biochar application techniques. One result of this work is the design of the Pilot CharTainer, capable of a 250 kgs-of-biomass-per-hour throughput delivering up to 50 kilograms per hour of the highest quality, tar-free, geo-conducting biochar available.

We are currently developing a pilot unit with CEC funding with the intent of commercial Production units being available as early as Q3 2021. We offer these data with reasonable confidence given our long-running data acquisition in the development of our gasifier-genset systems and distribution of their biochar byproduct.


Frequently Asked Questions

The Pilot version of the CharTainer will be shipped to strategic customers in CA starting first half of 2021. We expect to have units available to retail customers towards the end of 2021. Please send a message to to get on the interest list.

The CharTainer will be available in North America only for 2020 and 2021. We will advise on availability in international markets later in the year.

The Pilot CharTainer will cost around $300K USD depending on final configuration such as fuel handling balance of systems and biochar storage and handling. We are committed to lowering costs and expect to lower these prices as production volume increases.

Please review this Pilot CharTainer Spec sheet.

A Beta version of the unit can be observed at our facility in Berkeley CA. We expect the Pilot version to be operational at the same site in the summer of 2020. Please send a message to to schedule a visit.

Please review this Appropriate Feedstock link. We are developing novel reactor architecture that will widen the feedstock range such as finer fuels. Testing will be ongoing in 2020 and we will update the table as results are completed.

We are developing the CharTainer to be able to process hemp waste. Testing of this feedstock will be completed by April 2020 including an analysis of the biochar produced. Please stay tuned for updates at that time.

The quality of the biochar produced is highly conductive with low tar/PAH content. Please review this Skycarbon Specification which show biochar qualities and certifications for walnut feedstock. We expect that the general qualities to be similar for other feedstock.

The emissions are kept very low through a sophisticated cyclonic combustor with real-time NOx feedback for mixture optimization. Third-party emissions testing to EPA standards are being conducted in March 2020. We expect to share results at that time.

The CharTainer is a Combined Heat and Biochar unit (CHAB) with 20% biomass-to-biochar conversion rate. It does not have any electrical power output. The PowerTainer is a Combined Heat, Power and Biochar unit with 5% biomass-to-biochar conversion rate.

The CharTainer is being designed to process biomass waste streams on-site to minimize the waste disposal logistics and costs. The resulting biochar produced is a value-added product that can be used as a key ingredient in soil products. Examples of industries include – tree service companies, green waste recycling yards, cannabis growers and processors, nutshell producers, etc.
