As you search for VPN videos and other explainer videos to give you a lesson or two regarding how they are set up or how a product is used, you might have come across waste management guides, tutorials, and journals. Well, in the process, you may encounter terms that you are not conversant with, such as waste and biomass valorisation. The numerous links you click to get a glimpse of what this is about may lead to something new, and this can be annoying. Today, you have come to the right place!
What is waste and biomass valorisation?
Waste and biomass valorisation is a term that you will never fail to come across when waste management topic is discussed. It is simply the process by which waste is treated. The treatment can be done for several reasons. One of them is for disposal. It could also be done for sorting or even storage.
What really motivated the valorisation or treatment of waste is the depletion of materials. This saw the need for recycling of waste and residues to address the socio-economic concerns that had resulted from the exhaustion.
The process of waste valorisation
The method of waste and biomass valorisation involves the following major activities:
1. Processing of residue into raw materials
This is actually one of the most popular ways of waste valorisation. As the term suggests, the process merely involves the processing of waste or turning it into raw materials. It is quite straightforward. For instance, plastic bags can be processed and used to make computer cases and so on. Another good example is carbon dioxide. Being waste from plants or even humans, it is converted to methanol which is used to make fuel and other materials through a process known as carbon dioxide hydrogenation.
2. Finished or semi-finished products as energy sources
Some of the waste may be in the form of finished or semi-finished products. These residues are used as inputs for the production of other items. A good example is steel which can be used in the manufacturing of bicycles. Salt also is a good example and is used in food production.
3. Biomass Valorisation
When it comes to biomass valorisation, microwave technology is employed. In this process, heat is used to break down these waste products. Engineers and other stakeholders are also looking to improve the process by creating bacterial engines to increase the rate of biological decomposition.
Processes like pyrolysis are also employed to transform these materials chemically. Through biomass valorisation, fossil fuel and micronutrient fertilisers are created.The various valorisation techniques were invented to manage waste and also increase sustainability in the manufacturing industries. Engineers continue to research and develop new ways and processes that could make it more efficient.
