Explocom 1, Lupeni

Explocom is a family-owned business that has been producing BBQ charcoal since 1992. The company is now transitioning from BBQ charcoal to biochar for soil amendment and construction materials. In addition, Explocom produces liquid pyrolytic bio-condensate or wood vinegar. The feedstock is FSC certified sawmill waste. The company recently received the EBC certificate for sustainable biochar production.

Explocom uses the retort method of pyrolysis. The heat from the syngas combustion is used in the pyrolysis process and for drying incoming feedstock. Excess syngas can be captured and stored for renewable electricity production onsite. During pyrolysis, the biochar reaches a 600°C temperature and after the process is finished it is left for 24 hours to cool down and afterwards it is pulverized. Explocom sells biochar both in powder and in granular form under the brand name Gekka Biochar. They have plans to install additional machinery that will increase the biochar production capacity threefold.

The biochar has a carbon content of 78%. A lifecycle assessment (LCA) of Explocom’s production process was carried out by Accend in 2023. The LCA accounts for all process emissions from harvesting of the wood, transport to the production site, and the manufacturing of the biochar on-site and confirms that 2.41 tonnes of CO2 are removed by every 1 ton of biochar.

3rd party verification against the Puro Standard was completed in Q4 2023.

Renewable energy. Biochar production produces renewable energy as a bi-product.
Reduced use of fossil fuel based fertilisers
Green jobs: Biochar prodcution can increase employment and tax revenue in rural areas
Crop yields: Biochar improves soil health by increasing water retention, nutrient availability, and microbial activity.
Waste management: Biochar can be produced from waste materials such as agricultural waste, wood chips, and sawdust, reducing the amount of waste going to landfills.
Air pollution reduction: Biochar production reduces the amount of greenhouse gases and air pollutants generated by burning biomass waste.
Animal feed: Biochar can be mixed with animal feed to improve the nutritional value, weight gain and reduce the methane emissions from their digestion. Water purification: Biochar can be used to filter and purify water, removing pollutants and heavy metals.
Concrete production: Biochar can be used as an ingredient in the production of concrete, reducing the amount of cement used, and therefore the emissions generated during its production.
Aquatic life: The application of biochar to soils reduces phosphorus leeching into stream and waterways where it can cause eutrophication.
