Recovered energy provides „clean” energy sources. It can be energy recovered in the process of thermal waste transformation or as the heat from data centers and industrial heat. Using recovered energy involves retrieving energy that would otherwise be lost.
Using recovered energy
The concept of using recovered energy is very simple. First, we identify then remove any waste products that might be hazardous or can be recycled.Once the waste has been sorted, it is incinerated, which releases enough heat to produce steam. This steam is then fed into the pipe system to provide an energy source:it can drive turbines to produce electricity or can supply a whole neighborhood or city as a „collective central heating system”.
Using methane as energy source
Methane is a gas sourced from coal mines. Released into the atmosphere before being used, its impact on the air pollution is even 25 times greater than CO₂. However, methane can be a valuable source of energy, as its calorific value is twice of the coal calorific value. The electricity and heat generated from methane can be used for the producer’s own needs or it can be shared with clients.
The benefits of recovered energy
This type of energy offers an array of benefits. It can replace fossil fuels like gas, oil and coal with an energy source that would otherwise be „lost”. Unlike its carbon counterparts, however, recovered energy by definition creates no additional CO₂ emissions. It also provides a cheap source of energy that reduces production costs, provided the site from which the energy is recovered is not too far from the buildings or facilities to be heated.
