Black liquor is a byproduct of the paper-making process that is created during the chemical pulping of wood. It is a dark, viscous substance that contains lignin, hemicellulose, and other impurities from the wood chips used to make paper.
Black liquor is typically burned in a recovery boiler to generate steam and electricity for the paper mill. This process not only helps the mill become more self-sufficient but also reduces the amount of waste that needs to be disposed of.
Chemical Composition
Black liquor contains a high concentration of organic materials such as lignin, which is not useful in the paper-making process. It also has a high pH level, making it caustic and corrosive.
Recovery Process
After the black liquor is burned, the remaining chemicals and inorganic materials are used to make new pulping chemicals. This closed-loop system ensures that the paper-making process is more sustainable and eco-friendly.
Environmental Impact
While burning black liquor does release some greenhouse gases, it is considered a more environmentally friendly option compared to other methods of waste disposal. Its use in generating energy helps to reduce the reliance on fossil fuels.
Black liquor plays a crucial role in the paper-making industry by not only providing energy for the mill but also by reducing waste and promoting sustainability. Its utilization in the recovery process showcases the industry's commitment to environmental responsibility.
