Pyrolysis: An Introduction

Given that organic waste is the largest waste stream, one of the answers to the waste problem must deal with is organic waste. Currently these types of waste are generally landfilled, incinerated, or composted in some form. At best these technologies provide a cost recovery, but generally they are costly and are just a way to ensure the waste does not provide any health or other environmental problems.

A different way to deal with these types of waste is pyrolysis. Pyrolysis is the process whereby carbon based materials, such as organic waste, wood chips or rubber tires (to name a few examples), are placed in an oxygen deprived environment and heated to a point at which the composite chemical makeup of the feedstock separates and the molecules recombine into useable products like fuel oil, syngas and a charcoal like product called bio-char. The proportion and quality of these products depends on factors like the composition of the feedstock and the process parameters. The better the pyrolysis process the higher the quality of output products produced and the higher the market value.


Advanced Pyrolysis System

Our Advanced Pyrolysis System (APS) technology is now into its third generation. It includes several unique solutions that are operationally tested and years ahead of competitors. The process combines steam, direct heat, indirect heat, and a three stage fast pyrolysis ensuring a more complete penetration of heat into the feedstock, enabling a more complete and faster decomposition and ultimately higher quality by-products than competing technologies (see pyrolysis and marketable products). Further, the use of steam provides a built in safety feature against particulate combustion and avoids the necessity of near-vacuum required by conventional pyrolysis systems. This means that the APS is relatively safe and compared to competitor technologies produces much less, if any, air pollution.


The APS technology is operational, whereas competitors are characterized by R&D stage projects. As well, the process upgrades make the APS more flexible with regard to feedstock, being able to take many different types of feedstock as well as being robust with respect to impurities. The technology can easily change feedstock with minimal down time, while competitor technologies generally lack this flexibility. Emergent Waste Solutions offers its APS plants at low cost, efficient, modular and, in the future, a mobile alternative depending on the client needs. Competing technologies are easily twice the cost of the solution provided by our technology.
