Biochar is a variety of charcoal which is used as a nutritional supplement for soil.
Yes, cardboard can be used as biochar, provided it is free from harmful chemicals and additives. When heated in a low-oxygen environment during pyrolysis, cardboard transforms into biochar, which can improve soil health, enhance water retention, and sequester carbon. However, it is important to ensure that the cardboard is clean and uncoated to avoid introducing toxins into the soil.
Biochar is basically charcoal. It can be made from almost any biological substance rich in carbon, such as wood, straw, various kinds of plant material, compost and so on. It is usually made from wood because wood has a structure with various sized holes in it, mostly for conducting water or sap in the tree, and these form places where micro flora can live. When biochar is made, it is not processed at a high temperature, so the physical structure of the wood is not lost. Biochar benefits the soil by providing places for micro flora to life, holding water, and holding various nutrients to prevent them from washing away. The nutrients and water are available to plants with roots in or near the biochar, so it provides fertility to the soil. Biochar also has the benefit of providing for carbon sequestration, which is valuable for taking carbon dioxide out of the air and helping with global warming. Soil with biochar added is called terra preta.
The optimal application rate of biochar varies depending on the soil type, crop type, and climate conditions. As a general guideline, a common application rate of biochar is around 2 to 10 tons per acre for agricultural purposes. It is recommended to conduct soil tests and consult with experts to determine the most suitable application rate for specific conditions.
Biochar is charcoal made from wood or other similar material such as straw, which has large holes in it from the water and sap carrying veins remaining. In order to retain the structure of the wood, it is made at low temperature. Biochar provides places for micro flora to grow, and also holds water and nutrients that can be available for plants. Wnen mixed with soil, the result is terra preta. To be used, it is added to the soil of a garden or farm field and mixed in. It should be mixed in gently so as to prevent worms from being killed. It might make up 5% to 10% of the soil when the job is done, but it should not all be mixed in at once. Two or three years of adding smaller amounts is better. Once the biochar is in the soil, there should be no need to till. There should also be very little need to add fertilizer, though trace minerals might be added. In the Amazon, where the soil is mostly very poor, there are patches of biochar several thousand years old. The poor soil remains poor in nature, but the patches of biochar build up thicker every year. This is because of the biological activity in the biochar.
Il biochar è un eccellente ammendante agricolo di origine vegetale e pertanto consentito anche in agricoltura biologica. La sua struttura a spugna lo rende idoneo a trattenere l'acqua nelle sue pareti e irlasciarla gradatamente nel coso del tempo. Il biochar mantiene i terreni umidi anche durante lunghi periodi di siccità.
Wood pyrolysis is a thermal decomposition process that occurs in the absence of oxygen, where wood is heated to high temperatures, typically between 300 and 600 degrees Celsius. This process breaks down the wood into various components, including biochar, bio-oil, and syngas, which can be utilized as renewable energy sources or for other applications. The resulting biochar can improve soil quality, while bio-oil can be refined into fuels or chemicals. Overall, wood pyrolysis is a sustainable method for converting biomass into valuable resources.
Biochar is a form of charcoal produced from organic materials like wood, crop residue, or animal manure through a process called pyrolysis. It is rich in carbon and has a high surface area, which makes it a good soil amendment for improving soil fertility and carbon sequestration.

Pyrolysis is a process where organic materials are rapidly heated in the absence of oxygen, causing them to break down into simpler molecules like gases, liquids, and solids. This process can be used to convert biomass or waste materials into biochar, bio-oil, and syngas, which can be used as energy sources or chemicals.
Inside a pyrolysis reactor, organic materials are heated in the absence of oxygen to break down into smaller molecules, gases, and char. This process creates bio-oil, gases like methane and hydrogen, and solid biochar. These byproducts can be used for energy production and various industrial applications.
On average, 1 ton of bio-char can sequester around 3 tons of carbon dioxide per annum. This sequestration occurs as the bio-char is stable and does not decompose, effectively locking the carbon in the soil for an extended period.
Biomass is being used as a renewable energy source by converting organic materials such as wood, crop residues, and animal waste into heat, electricity, or biofuels. This process helps reduce greenhouse gas emissions and provides a sustainable alternative to fossil fuels for power generation and heating. Biomass can also be used in the production of bioplastics, biochar, and other bioproducts.
