FAQ

What makes the Waste Conversion Pyrolysis system stand out?

 

Our system is a state-of-the-art long-term solution for municipal and industrial waste disposal, providing the municipalities or factories it serves with additional income from selling its by-products, and the surrounding communities with clean renewable energy.

 

Our system offers an environmentally friendly way of disposing waste and generating energy, helping to address climate change. Therefore, the projects implementing the Waste Conversion Pyrolysis technology qualify for green energy tax reductions. The system has the potential to reduce GHG emissions each year by millions of tons of CO2 equivalent. Moreover, it will provide you with a cleaner and safer environment, avoiding public health risks and ecology program expenses.

 

Why is the Waste Conversion Pyrolysis system considered a renewable energy source?

 

As a rule, solar, wind, and geothermal power are considered renewable or green energy.

 

Our system allows for transformation of a percentage of waste into a gaseous substance which after depuration serves as fuel to produce electrical energy. The continuous feed of waste constantly produced by our communities allows for a constant and reliable energy source.

 

Thus, the more waste we manage, the more energy we receive.

 

What products do we receive as result of the pyrolysis process?

 

Our main product is electricity. This energy source is a fundamental part of business, pleasure and everyday life. In this regard, the electricity generating function of our units is fundamental as well, and it is in everyone’s best interest that this integral part of our system be maintained. The coefficient energy output from a steam gas generator is 30% and cogeneration gas turbines working on depurated syn-gas provide approximately 60-80%. Thus, treating 125 tons of waste a day using one of our Waste Conversion Pyrolysis systems we receive 5 to 10 MW*h or even more, depending on the feedstock's chemical composition.

 

The next byproduct is carbon char. Depending on the feedstock, we have put our carbon production at anywhere between 2 and 10%. Even though this amount of carbon still beats out incineration and other technologies, we went ahead in our patented high-temperature technological process and eliminated virtually any dioxins, furans or other toxins in it thereby making it commercially usable. This allows us to provide more revenue for you and a greater environmnetal safety for our process.

 

What energy source is used to power the Waste Conversion Pyrolysis system?

 

Our system does require heat to begin the conversion process. We use natural gas or propane-butane tanks to provide us with the initial heat. Once the units have achieved the sufficient amount of heat, the waste material is what is used to circulate a constant source of heat. After the initial start, the unit compensates for up to 60% of the energy needed in the operation of the system.

 

Waste heat from the pyrolysis reactor is also recovered and reused in order to provide as much energy output as possible.  We don’t waste any heat and recycle all of our by-products.

 

Why hasn't pyrolysis process been used before?


Pyrolysis has been known for hundreds of years, primarily used in a batch feed system.  Until recently, however, it has not been engineered effectively as a continuous feed system, which would allow for the use of the by-products, such as carbon char, and process mixed waste such as MSW on a continuous basis.  Green Light Energy Solutions has developed a commercially viable pyrolytic conversion system that is efficient, reliable, continuous, and environmentally safe, even with mixed municipal waste.

 

In the past, a general abundance of inexpensive electrical power and ample landfills have limited the commercial viability of conversion technology.  However, now with the growing need for energy, closures of landfills, the high cost of opening new ones, and negative environmental impact of incinerating, pyrolytic technology now offers an environmentally safe and cost effective solution for "waste-to-energy" facilities.

 

How long is the financial return period?

 

The Waste Conversion Pyrolysis system is a cost-effective solution. The value proposition for our customer is that it would recapture revenue from four sources: 

 

    1) Waste disposal (tipping) fees for approx. 300 tons per day with revenues of $5.5 million per year (at price of 50 USD per 1 disposed ton),

    2) Distributed power generation of 5MW with revenues of $5.9million per year (at price of 0.15 USD per 1 generated kW*h),

    3) Revenue from selling recyclable materials amounting approximately 40 tons per day of $2.9 million (at average price of 200 USD for each recycled ton), and

    4) Creation of up to 0.33 million carbon credits. 

 

Generally speaking, project payback can lower down to 5-6 years, yet precise data can only be calculated depending on a particular project.

 

What is the cost of the turn-key operating facility?

 

GLES is an equipment production company and its activity is limited by the production and sales of the proprietary pyrolysis system, excluding the standard equipment for waste pre-processing and for energy generation (heat recovery steam generator or boiler, steam turbine, subsystem, transformer). The cost of the turn-key project thus depends on the cost of the equipment chosen and on the cost of construction and engineering works, infrastructure, utilities connection, acquire of permits and licenses and other services and therefore can only be determined by a general contractor implementing the project.  

 

Please give an idea on processing old tyres with the WCP equipment.


The equipment requires that the waste has diverse morphological composition, i.e. up to 20% of tyres or plastic and 80% of any other organic waste. The point is that our system loaded with the waste of high-carbon content will not produce much gas, but a great amount of solid residue and tar.  We would recommend to add organic waste to the tyres you are going to process.

 

Can GLES recommend general contractor to implement turn-key Waste-to-Energy Project?


We should kindly recommend to work with Technip Stone & Webster Process Technology, Inc. (Technip),  one of the leading global Engineering, Procurement, and Construction (EPC) service provider to the energy industries. To launch the process kindly fill in the Technip WTE Project Summary.

 

Is the technology certified? Kindly provide the environmental sustainability certificates.

 

Technology and equipment were tested in full 125 TPD scale (loaded with the presorted and dryed mixed MSW) and proved its efficiency and invoronmental safety. Independent international agency SGS made and an official  report on the air emissions of the WCP facility.


What about the maintenance of one operating processing line?

 

Scheduled maintenance work is required,  and is standard for the used gearmotors, compressors, air blowers, sensors and other (visual check, lubricating, oil change, overaged sensors replacement, etc).

Scheduled maintenance may be done by the operator-company according to the maintenance regulation. 


Unique GLES components do not require scheduled service and are designed to operate with only visual check.
