Biochar Carbon Removal
Biochar carbon removal (also called pyrogenic carbon capture and storage) is a negative emissions technology. It involves the production of biochar through pyrolysis of residual biomass and the subsequent application of the biochar in soils or durable materials (e.g. cement, tar). The carbon dioxide sequestered by the plants used for the biochar production is therewith stored for several hundreds of years, which creates carbon sinks. Definition The term refers to the practice of producing biochar from sustainably sourced biomass and ensuring that it is stored for a long period of time. The concept makes use of the photosynthesis process, through which plants remove CO2 from the atmosphere during their growth. This carbon dioxide is stabilised within the biochar during the production process and can subsequently be stored for several hundreds or thousands of years. Biochar Carbon Removal falls into the category of carbon dioxide removal (CDR) technologies.Constanze Werner et al. ...

Carbon Capture And Storage
Carbon capture and storage (CCS) is a process by which carbon dioxide (CO2) from industrial installations is separated before it is released into the atmosphere, then transported to a long-term storage location.IPCC, 2021Annex VII: Glossary atthews, J.B.R., V.

Soil Fertility
Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.Bodenfruchtbarkeit Retrieved on 2015-11-09. It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time. A fertile soil has the following properties: * The ability to supply essential plant nutrients and water in adequate amounts and proportions for plant growth and reproduction; and * The absence of toxic substances which may inhibit plant growth e. ...

Terra Preta
''Terra preta'' (, literally "black soil" in Portuguese language, Portuguese), also known as Amazonian dark earth or Indian black earth, is a type of very dark, fertile human impact on the environment, anthropogenic soil (anthrosol) found in the Amazon Basin. In Portuguese its full name is or ' ("black soil of the Indigenous peoples of the Americas, Indian", "Indians' black earth"). ''Terra mulata'' ("mulatto earth") is lighter or brownish in color. ''Terra preta'' owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bones, broken pottery, compost and manure to the low fertility Amazonian soil. A product of indigenous Indigenous peoples of the Amazon, Amazonian soil management and slash-and-char agriculture, the charcoal is stable and remains in the soil for thousands of years, binding and retaining minerals and nutrients. ''Terra preta'' is characterized by the presence of low-temperature charcoal residues in high ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dark Earth
In geology and archaeology, dark earth is a substratum, up to thick, that indicates settlement over long periods of time. The material is high in organic matter, including charcoal, which gives it its characteristic dark colour; it may also contain fragments of pottery, tile, animal bone and other artefacts. It is interpreted as soil enriched with the sooty remains of thatched roofs from houses without chimneys, with other waste materials. In some areas it appears to give the soil added fertility. London's dark earth was originally called 'black earth' by archaeologists. It was renamed 'dark earth' because of confusion with the ''chernozem'' (black earth soils in Russia), whose dark colour is traditionally (not universally) thought to come from humus, rather than soot. Charred material as agricultural improver In the Hebrides, it was customary to remove the thatch from the "black houses" every spring, and spread it on the fields as fertilizer, improved by the soot which it re ...

List Of Emerging Technologies
This is a list of emerging technologies, which are emerging technologies, in-development technical innovations that have significant potential in their applications. The criteria for this list is that the technology must: # Exist in some way; purely Hypothetical technology, hypothetical technologies cannot be considered emerging and should be covered in the list of hypothetical technologies instead. However, technologies being actively researched and prototyped are acceptable. # Have a Wikipedia article or adjacent citation covering them. # Not be widely used yet. Mainstream or extensively commercialized technologies can no longer be considered emerging. Listing here is not a prediction that the technology will become widely adopted, only a recognition of significant ''potential'' to become widely adopted or highly useful if ongoing work continues, is successful, and the work is not overtaken by other technologies.

Climate Engineering
Geoengineering (also known as climate engineering or climate intervention) is the deliberate large-scale interventions in the Earth’s climate system intended to counteract human-caused climate change. The term commonly encompasses two broad categories: large-scale carbon dioxide removal (CDR) and solar radiation modification (SRM). CDR involves techniques to remove carbon dioxide from the atmosphere and is generally considered a form of climate change mitigation. SRM aims to reduce global warming by reflecting a small portion of sunlight (solar radiation) away from Earth and back into space. Although historically grouped together, these approaches differ substantially in mechanisms, timelines, and risk profiles, and are now typically discussed separately.IPCC (2022Chapter 1: Introduction and FramingiClimate Change 2022: Mitigation of Climate Change.

Pyrolysis
Pyrolysis is a process involving the Bond cleavage, separation of covalent bonds in organic matter by thermal decomposition within an Chemically inert, inert environment without oxygen. Etymology The word ''pyrolysis'' is coined from the Greek language, Greek-derived morpheme, elements ''pyro-'' (from Ancient Greek : - "fire, heat, fever") and ''lysis'' ( : - "separation, loosening"). Applications Pyrolysis is most commonly used in the treatment of organic compound, organic materials. It is one of the processes involved in the charring of wood or pyrolysis of biomass. In general, pyrolysis of organic substances produces volatile products and leaves Char (chemistry), char, a carbon-rich solid residue. Extreme pyrolysis, which leaves mostly carbon as the residue, is called carbonization. Pyrolysis is considered one of the steps in the processes of gasification or combustion. Laypeople often confuse pyrolysis gas with syngas. Pyrolysis gas has a high percentage of heavy tar ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Composite Material
A composite or composite material (also composition material) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Composite materials with more than one distinct layer are called ''composite laminates''. Typical engineered composite materials are made up of a binding agent forming the ''matrix'' and a Filler (materials), filler material (particulates or fibres) giving ''substance'', e.g.: * Concrete, reinforced concrete and masonry with cement, lime or Mortar (masonry), mortar (which is itself a composite material) as a binder * Composite wood such as glulam and plywood with wood glue as a binder * Reinforced plastics, such as fiberglass and fibre-rein ...

Durability
Durability is the ability of a physical product to remain functional, without requiring excessive maintenance or repair, when faced with the challenges of normal operation over its design lifetime. There are several measures of durability in use, including years of life, hours of use, and number of operational cycles. In economics, goods with a long usable life are referred to as durable goods. Because there is no objective measure of durability for clothing, price has become an important indicator. Requirements for product durability Product durability is predicated by good repairability and regenerability in conjunction with maintenance. Every durable product must be capable of adapting to technical, technological and design developments. This must be accompanied by a willingness on the part of consumers to forgo having the "very latest" version of a product. In the United Kingdom, durability as a characteristic relating to the quality of goods that can be demanded by ...
