What is carbon removal? Carbon removal, also known as carbon dioxide removal (CDR) or carbon drawdown, is the process of capturing carbon dioxide (CO2) from the atmosphere and locking it away for decades or centuries in plants, soils, oceans, rocks, saline aquifers, depleted oil wells and other geological reservoirs, or long-lived products like cement. Scientists have proposed many different methods of carbon removal. Some of these are already in use at relatively small scales, whereas others remain in the early stages of research and development. Technologies and practices for implementing carbon removal are often called negative emissions technologies (NETs). Carbon removal is not the same as carbon capture Although they are often conflated, carbon removal is importantly different than fossil carbon capture and use or storage (fossil CCUS). Carbon capture and storage (CCS) captures CO2 from a smokestack or flue, such as in a gas-fired power plant or a cement factory, and then s...

  The relationships between pollution and economic development are complex with several possible feedback loops that are predicated on drivers and consequences of economic growth, ecosystem resilience and the ultimate reliance of financial capital on nature. The aim to achieve the sustainable development goals (SDGs) is an opportunity to revise and organize the debates between pollution and economic development. Each year more than 30 giga-tons of CO2 are released into the Earth’s atmosphere: this is the main source of the greenhouse gases that contribute to climate change. The largest part of these gases comes from the use of fossil fuels, the generation of energy through non-renewable channels and polluting human activities. The last report of the World Meteorological Organization (WMO) pointed out that during the last year recorded (2020), the concentration of CO2 in the atmosphere broke another record, despite a drop in fossil fuel emissions during the Covid-19 pandemic. Sp...

  What is a 3D printer? 3D printer is a new technology t he birth of 3D printing was in 1984 in the hands of Chuck Hull who invented a process known as stereolithography in which layers are added by curing photopolymers with UV lasers, after that layer by layer technology used in each layer has 0.1mm depth, in 1999 it was first used in medicine then parts of human such as ears, fingers  was done,  in 2005 3D  printing technology  became open  source, in  2006 the  first SLS (selective laser sintering) machine became variable, in 2008 the first self-replication printer which made the printer able to print the majority of its own components. Main Components Of 3D Printer Print Bed: The print bed is a flat surface where the extruder deposits the filament from solid objects. This bed is heated while printing but it depends upon which filament or material we are going to use. Most of the beds are made of aluminum but now a days there is also gla...
