Mobile pyrolysis plant technology to produce standard charcoal and biochar
Summary:
UK-based multi-national environmental science and engineering firm has developed a complete mobile batch pyrolysis plant technology to produce standard charcoal and biochar. The technology can be used to pyrolyse any unchipped woody biomass where transport or economic issues preclude removal. The biochar product can be used as a highly valuable soil amendment for agriculture. Partnership sought on commercial or technical agreement basis.
Description:
The UK-based multi-disciplinary environmental science and engineering firm develops/implements innovative and effective solutions in areas as diverse as environmental and social management and impact assessments, water management and treatment, energy and carbon, waste management, climate change, international development, and sustainability and environmental information.

The company has developed a mobile batch pyrolysis plant technology to produce standard charcoal and biochar applicable to any log or stick-sized woody biomass. Pyrolysis is the high temperature treatment of the woody waste in a low oxygen environment. Pyrolysis converts the woody waste into a special form of char known as biochar, which has a variety of valuable applications. Biochar is typically used as a soil amendment, with other potential applications of char products, including manufacture of BBQ fuel, activated carbon, or filtering media.

The technology and the support systems around it make the entire process a unique offering as all activities are conducted in-situ - the process provides a complete biochar processing solution at the biomass location. The technology can accept log or stick sized woody biomass (no chipping required) and is loaded using standard machinery (e.g. loader or forklift etc). The biochar product is then screened, crushed and quenched on site and loaded into bulk bags ready to go. All of this is accomplished with the technology and standard machinery and so provides a complete pyrolysis plant for farming, forestry, and other waste management operations.

The technology has been operated extensively in Australia over the past four years; wood wastes processed have included softwoods (e.g. willow, poplar, pine etc), hardwoods (e.g. eucalyptus, mahogany, jarrah etc), municipal greenwaste, demolition wood waste and railway sleepers.

Multiple pyrolysis units can be deployed with bolt-on electricity generation for a longer-term bioenergy hub arrangement. The technology is also particularly useful for the in-situ treatment of diseased trees and plants, providing a method of complete destruction of pathogens with minimal risk of spread. A sophisticated thermal oxidiser arrangement also makes the technology suitable for certain contaminated biomass sources where contaminants can be volatilised and destroyed in the high temperature flue system.

Key benefits include:
· environmentally friendly, easy/safe to use
· sequester carbon for potential carbon credit generation
· much lower capital outlay than fixed plant installations
· reduced regulatory requirements compared with fixed installations
· no site works required
· no on-site power requirements
· arrives fully operational - no lengthy setup and commissioning
· modern control system minimises operator time
· excellent payback time and internal rates of return
· practical - no chipping required

Cooperation is sought with industry partners, government and non-government organisations active in farming, forestry, construction, waste management and other industries which produce stranded or uneconomical woody biomass situations; as follows:

1. commercial agreement with partners seeking to trial or purchase the existing technology
2. technology agreement with partners interested in collaborating to further develop the technology for specific feedstock types
Advantages and Innovations:
The transportable pyrolysis furnace´s key parameters:

· Easily transported unit/access to most remote areas.
· Batch processing with 15 m3 internal volume per batch (~3 to 6 tonnes (metric) of undried timber feedstock.)*
· Pyrolysis converts biomass to ~1 to 2 tonne biochar per batch*.
· Processes larger wood feedstocks, including logs. Minimal feedstock pre-treatment is required (no chipping required). To process larger woody feedstocks in a suitable time, the maximum recommended woody dimensions are: no greater than 150 mm diameter (6¿).
· Batch processing takes a few hours, normally 4~5 hrs per batch depending on moisture content and wood feedstock diameter (for diameter less than 150 mm (6¿), processing should be less than five hours).
· Targeted processing temperature range can be selected from 300-550oC.
· Destruction of all pathogens.
· Biochar product has very high fixed carbon content.
· Very low emissions.
· High thermal energy output.
· No smoke: the high thermal oxidiser temperature minimises volatile emissions. When operating there are no visible smoke emissions - the technology can therefore be operated in an urban environment.
· Designed for farm, forestry and waste management operations.
· The biochar product is screened, crushed and packaged at the end of the process on site.
· A sophisticated control system with multi-sensory input. Once ignited, operator input requirements are minimal. It can be operated unattended, monitored and controlled remotely via smartphone and will quench and shut itself down at the conclusion of the process. This allows unattended operation overnight.
· Optional heat recovery for drying/space heating.
· Optional wood vinegar and bio-oil recovery system.
· Optional small-scale power generation.
