Aurutris Waste to Energy™ Process Overview

The Waste to Energy™ Process

Aurutris is the first company to prototype a commercially scalable Waste to Energy™ facility with ground breaking and patented technology. We use a process called, Hydrothermal Decomposition to produce an Engineered Pulverized Fuel (EPF). Our  Waste to Energy™ facility utilizes a number of previously proven technologies that have been used in Asia and Europe for MSW, sludge, medical waste and vegetation waste processing. These technologies have been brought together to form the Green Waste to Energy™ process architecture.

The Hydrothermal processing system, known as the Resource Recycling System (“RRS”), was originally developed by  Hokuto Kougyo Co of Japan, one of the key partners of Aurutris, for the disposal of hazardous hospital (red bag) wastes and the patented production of a wood powder, used for the manufacturing of Bio Plastic. The Complete Combustion Chamber system (“CCC”), a technology developed by Jasper in Germany, another key partner of Aurutris, is used for the combustion of processed waste such as MSW, biomass and industrial wastes. The Resource Recycling System generates waste water which must be treated before discharge to a municipality wastewater treatment plant. The Waste Water Treatment System (“WWTS”) is a technology developed by ETC of South Korea, for the treatment of industrial wastewater. Aurutris also incorporates other conventional equipment for receiving, sorting, shredding and storing MSW/sludge prior to the Hydrothermal treatment and combustion of the Engineered Pulverized Fuel (EPF), as well as conventional heat recovery and steam turbine equipment for recovering useful energy from the combustion process. A highly advanced air quality control system is also incorporated.

The First Sustainable Zero Emissions Waste Processing Solution

At the moment, the planet is facing extremely complicated environmental challenges. Our land is overflowing with unhealthy landfills and outdated waste processing techniques which produce by-product pollutants that threaten our air, water and food chain.

Aurutris’s Waste to Energy™ process brings the first truly sustainable solution for waste processing to the world. We are able to tackle two problems with one facility. Our increased demand for energy and the disposal of our waste. Our patented technology brings a sustainable bridge to a healthy environment from the clean processing of waste through to the delivery of electrical energy. We are able to process both municipal solid waste and sewage sludge with near Zero Emissions. As by-products, we produce an Engineered Pulverized Fuel (EPF) and then electricity. Other than initial startup, this integrated process requires no fossil fuels to operate the facility. Aurutris has developed this innovative solution by combining a variety of trade secrets, patented and patent pending technologies from partners in Japan, South Korea, and Germany.

6 Key Steps – Aurutris Waste to Energy™ Process

Aurutris facilities include all necessary equipment and systems to receive and process municipal solid waste (MSW) and bio-solids into a prepared fuel (Aurutris Engineered Pulverized Fuel or EPF). EPF is then combusted to produce steam for both the Resource Recycling System (RRS) and the turbines that generate electricity which can be sold to the grid.

The Aurutris Waste to Energy™ process consists of the following major process areas:

- MSW/Sludge receiving and pre-processing;
Hydrothermal Treatment of waste and bio-solids into pulverized fuel;
Dewatering and drying of the pulverized fuel;

Additional processes for Aurutris  Waste to Energy™:

- Combustion of the pulverized fuel;
Steam production and electric generation, and;
- Waste water treatment and air pollution control.

Advanced Air Quality Control System

Aurutris facilities incorporate a sophisticated multi-pollutant air quality control system (AQCS). The AQCS will include the following major components:

- Twin Cyclone for initial particulate removal;
Selective Catalytic Reduction (SCR) with urea injection to reduce NOx and VOC;
- Fabric filter baghouse to control particulate matter (PM) and metals;
- Wet Scrubber with sodium hydroxide to control SO2, HCl, HF and; 
- Carbon Adsorption system to control mercury (Hg) and VOC.
