The current processing methods for paper sludge are based on diverse methods of incineration and landfilling. Although there has been an increase in energy recovery from the burning processes, a paper sludge molecule is mainly composed by water and cellulose, which makes this way of disposal quite ineffective and energy demanding.

The table below compares some of the current paper sludge disposal methods with DBG’s process. It can be observed that our technology does not recycle the waste but it upcycles it. This is achieved thanks to our patented enzymatic process where biomimicry is thoughtfully applied, and which allows the heating value of paper sludge (11 MJ/kg for our sludge mix) to increase and obtain 5 times more energy out of it. Paper sludge coming in, bioLNG coming out.

Moreover, the energy requirements are significantly lower than incineration methods and no harmful emissions are released to the environment during the processing

“Paper sludge coming in, bioLNG going out.”
