The Organics Pyroclast
The Organics Pyroclast is a thermal decomposition technology that converts biomass waste materials into biochar. It can also be used to convert RDF from MSW into ash.
The system utilises a patented closed-loop pyrolysis chamber that operates in the absence of oxygen to break down biomass and produce biochar. Material is carbonised at a temperature of 450-800°C in a patented tube-screw reactor with a slow residence time up to 30 minutes.
Configured around a standard ISO container, for ease of transport and shipping, depending on feedstock a standard unit is rated 0.5 – 1.0 tph feed on a continuous basis.
Biomass material, such as agricultural residues, woody wastes, and organic wastes are typically dried to <20% moisture content and reduced into particles with a nominal size of 20-50mm to facilitate efficient loading and conversion to biochar.
The prepared biomass is loaded into the pyroclast reactor designed to withstand high temperatures and prevent ingress of air.
The pyrolysis process operates at temperatures between 450º to 800ºC dependent on feedstock and required product characteristics. As the reactor reaches the target temperature, the biomass undergoes thermal decomposition.
The Pyroclast utilises a slow pyrolysis process that ensures by controlling temperature and residence time we maximise the production of biochar.
Syngas is then fed into a thermal oxidiser where it is combusted to produce heat, steam, or electricity. This energy can be used on-site to power the pyrolysis process or exported to the grid.
The biochar generated from the Pyroclast can be used in various ways. It can be directly applied to soils as a nutrient-rich soil amendment, improving soil fertility, water retention and generate VCM credits for lon term carbon sequestration.
Biochar can also be used in construction materials, as a filtration medium, or as a carbon source in industrial processes such as cement and ferrosilicon manufacture.
Biochar Explained
Photosynthesis is the process that plants employ to absorb the carbon dioxide needed to grow. The carbon is stored in the plant and the oxygen is released into the atmosphere; a highly efficient system that maintains nature’s balance. The carbon is then stored in the plant until the end of its life. But, when the plant dies, or is cut down, the carbon is released back into the atmosphere in the form of CO2. Sustainable management of biomass, in which carbon has been stored involves prevention of the carbon from being released back into the atmosphere. The most effective manner of achieving this is by using pyrolysis, an ancient technique first used over a three thousand years ago.
Biochar is an organic product created by heating biomass in an oxygen-free environment. This process produces a stable form of carbon, which can be used as a soil amendment to improve soil health, as well as a carbon sequestration method to reduce greenhouse gas emissions. Biochar can also be used to generate carbon credits, which are tradable certificates that represent reductions in greenhouse gas emissions.
Carbon Sequestration
Biochar is a carbon-rich solid material produced by pyrolysis involving the heating of biomass in the absence of oxygen. Biochar can contribute to carbon sequestration via:
1. Carbon Capture: During the pyrolysis process, organic materials, such as agricultural waste or forestry residues, are heated, leading to the release of volatile gases and leaving behind carbon-rich biochar. This carbon capture process prevents the carbon in the biomass from being released into the atmosphere as carbon dioxide (CO2), a greenhouse gas that contributes to global warming.
2. Long-Term Carbon Storage: Biochar has a high carbon content and is resistant to decomposition. When applied to soils, it can act as a long-term carbon sink, effectively sequestering carbon for significant periods, potentially ranging from decades to centuries. The stability of biochar in soil allows for the retention of carbon that would otherwise be released back into the atmosphere through decomposition processes.
3. Soil Improvement: Biochar offers several soil-related benefits, including improved water retention, enhanced nutrient cycling, and increased microbial activity. These properties can contribute to increased agricultural productivity and soil health. Additionally, the presence of biochar in soil can provide a habitat for beneficial soil organisms, which further support plant growth.
4. Reduction of Nitrous Oxide Emissions: Biochar application to agricultural soils has been found to reduce nitrous oxide (N2O) emissions, another potent greenhouse gas. Nitrous oxide is released through microbial processes in soils, especially in nitrogen-rich environments. Biochar’s porous structure and chemical properties can help mitigate N2O emissions by providing a stable environment for microorganisms involved in nitrogen cycling.
5. Co-Benefits: Apart from carbon sequestration, biochar has potential co-benefits such as reducing nutrient runoff from agricultural fields, improving soil fertility, and reducing the need for synthetic fertilizers. These co-benefits can enhance agricultural sustainability and contribute to environmental and economic gains.
It is important to note that the actual carbon sequestration potential of biochar depends on several factors, including the type of feedstock, production methods, application rates, and soil conditions. Additionally, the sustainability of biochar systems must consider the life cycle analysis of the entire process, including biomass sourcing and energy requirements for pyrolysis.
Biochar in Agriculture
Soil Improvement: Biochar is known to enhance soil fertility and structure. When added to soil, it improves water retention, reduces nutrient leaching, and increases nutrient availability for plants. It also provides a stable habitat for beneficial microorganisms that support plant growth.
Nutrient Retention: Biochar has a high cation exchange capacity (CEC), which means it can hold and exchange essential plant nutrients like potassium, phosphorus, and calcium. This helps prevent nutrient runoff and leaching, allowing plants to access these nutrients over an extended period.
pH Regulation: Depending on its source material, biochar can have varying effects on soil pH. Some types of biochar have a neutral pH, while others may be slightly alkaline or acidic. This can be advantageous for farmers as it helps regulate soil pH, making it more suitable for optimal plant growth and nutrient availability.
Disease and Pest Management: Biochar can indirectly contribute to disease and pest management. It enhances soil microbiota diversity, promoting the growth of beneficial microbes that suppress pathogenic organisms. Additionally, the porous structure of biochar can provide a physical barrier against certain pests.
Water Management: Biochar improves water holding capacity in soil, reducing water loss through evaporation and increasing water availability to plants during dry periods. This can be particularly beneficial in areas prone to drought or with sandy soils that have poor water retention.
It is important to note that the effects of biochar can vary depending on factors such as the type of biochar used, soil type, climate, and crop species. Therefore, it is recommended to consider site-specific conditions and conduct proper research or consult with agricultural experts when implementing biochar applications in agriculture.
Biochar and Carbon Credits
Production of biochar from biomass residues prevents a large part of the carbon contained in the biomass from escaping into the atmosphere. The Pyroclast locks in up to 3 t CO₂ per tonne of biochar (with approx. 80% C-content for more than 1000 years.
If this biochar and the CO₂ bound in it is put into a permanent carbon sink as a soil improver or filler, the recycler receives carbon offset credits.
Engineered Biochar
The incorporation of biochar into construction materials is an active field of development and research. It has considerable potential for being incorporated into materials such as concrete, cement, and asphalt, offering potential benefits in terms of sustainability and carbon sequestration.
Concrete: Concrete is a widely used construction material that consists of cement, aggregates (such as sand and gravel), and water. Researchers have been exploring the addition of biochar as a partial replacement for cement in concrete mixes. The addition of biochar can enhance certain properties of concrete, such as reducing its density, improving thermal insulation, and potentially enhancing its mechanical strength. Additionally, the incorporation of biochar in concrete can potentially sequester carbon and offset the carbon emissions associated with cement production.
Cement: Cement is a key component of concrete and is responsible for the release of a significant amount of carbon dioxide during its production. One approach being studied is the use of biochar as a partial replacement for cement in the production of low-carbon or carbon-neutral cements. This can help reduce the overall carbon footprint associated with cement production and contribute to carbon sequestration.
Asphalt: Asphalt is commonly used in road construction and paving. Research is underway to explore the incorporation of biochar into asphalt mixtures. The addition of biochar to asphalt can potentially improve its mechanical properties, such as durability and resistance to cracking, while also providing opportunities for carbon sequestration.
In all of these applications, the use of biochar in construction materials offers the potential to sequester carbon and reduce the overall carbon footprint of the built environment.
Research and development in these fields are ongoing to optimise these applications and ensure their viability on a larger scale.
It’s important to consult with experts and follow industry guidelines and standards when considering the incorporation of biochar into construction materials to ensure the desired outcomes in terms of sustainability, performance, and carbon sequestration.
