What is organic?

We most commonly think of the term "organic" in relation to naturally grown foods, so you may think the UTOC is able to consume only plant matter.  Chemically speaking, the term "organic" refers to anything that includes carbon-bonded atoms, including plastics, rubber, various chemicals and gases, and biological material.  All organics, by the chemical definition, can be processed by UTOC. 

UTOC ash is the metal and mineral fractions of UTOC feedstocks.
See our list of UTOC feedstocks.

Isn't UTOC just an incinerator?

No.  UTOC burns far hotter than an incinerator, utilizes flameless combustion technology, has lower CAPEX and O&M costs, and has significantly lower emissions; a summary of the more significant of UTOC’s many differentiations.

Isn't combustion bad?

Burning waste is bad for the environment because it creates toxic vapors and particulate that cause all manner of health problems. Open garbage fires are the worst offenders and yet almost half of the world's waste is disposed of this way.

Emerging technologies are working to find solutions to the world's garbage and sewage problems, some of them promising and some not, but all helping to advance our efforts. What they all do is challenge what we think we know, and only as we adopt new ways of thinking can we advance. Einstein said, "We cannot solve our problems with the same thinking we used when we created them."

UTOC does emit carbon dioxide and trace amounts of toxins while recycling waste, but it is cleaner, cheaper and more efficient than conventional technology today, and it will get rid of the garbage. This is a much healthier solution compared to open garbage fires or scattering garbage around the countryside and in our waterways and growing landfills, leaching toxins, attracting vermin and disease, and releasing odors and methane for years to come.

People who openly condemn new technology without merit, slow down progress, whether they are biased, unaware of the advances being made, citing outdated technology reports, or clinging to impractical ideals about recycling. Meanwhile, the garbage continues to pile up.

Ideally, we should recycle everything, and because of that we refer to UTOC as the "recycler of last resort." But until we learn to cleanly and sustainably recycle everything, we need an effective clean solution now that will stop the world choking on its own waste.

Why reclaim landfills?

Reclaimed land could be used for parks and other development, it would reduce the generation of greenhouse gases, it would help us save on carbon taxes, and would significantly offset fossil fuel electricity and heat production costs and environmental impacts; a significant contribution to cleaning up the planet.

And since UTOC can pay for itself, this would cost us very little.

Isn't ash disposal as problematic as waste disposal?

No, because UTOC ash is only the metal and mineral fractions of feedstocks, zero organic material.  Plus, depending on laboratory analysis, UTOC ash can be an agricultural land nutrient or used as asphalt/concrete aggregate.

How much ash is produced from 1,000 tonnes of municipal waste?

Approximately 66 tonnes.

Would that ash go to a landfill?

No, not necessarily.  Ash has numerous industrial uses so can be recycled if you have the facility to do so.

What gases does UTOC release into the atmosphere?

Approximately 22.5% water, 19.5% carbon dioxide, 57.0% nitrogen, 1.0% oxygen, 30 mg/m^3 NOx; zero carbon monoxide, zero methane.

What is required for maintenance of the UTOC?

There is a detailed manual of specific maintenance needs for the life of the UTOC, all of which can be done by qualified service contractors. UTOC items that require routine maintenance are external/insertion components such as actuators, drives, augers, sensors, and the like. Our technical staff are available for consultations by email and mobile phone during normal business hours (9am to 5pm CST).  Our representatives travel to project sites when required to support UTOC system service personnel.

Does UTOC require Municipal Solid Waste to be sorted?

No.  There is no requirement to sort, blend, or manage feedstock; just shredding down to 75mm lump size.  UTOC safely recycles all organic waste, including "un-recyclable" plastics.  Inorganics (metals and minerals) that enter the UTOC exit as ash.

Does all UTOC feedstock have to be dry?

UTOC can process any organic feedstock with up to approximately 65% moisture content.  That includes pesticides and various other chemicals, sewage sludge, household containers that still have food in them, and even wet paper and cardboard that is typically not recyclable.

Do the shredder and auger require a lot of maintenance?

The shredder requires no more than any other piece of industrial equipment.  The auger requires very little maintenance due to its very low speed, approximately 1/150 the speed of conventional augers.

Can the UTOC operate continuously?

Yes.  Continuous operation is much preferred as long as the UTOC is supplied with feedstock at its minimum processing rate, approximately 15% of design processing capacity.

Who can operate the UTOC?

Labour workforce entry personnel can operate and perform routine UTOC maintenance after receiving our initial training.  Our technicians are available remotely to assist with problems that may arise

What is required to start and maintain the operation of the UTOC?

Each UTOC startup takes 24 to 36 hours.  Once the 1000°C minimum operating temperature is reached, the UTOC operates continuously with no supplemental fuel or other thermal energy inputs as long as feed rates exceed its minimum requirement, approximately 15% of design capacity.  Smallest UTOC system capacity is approximately 5.5 tonnes of Municipal Solid Waste per day.

How does the UTOC system compare to other similar systems?

UTOC utilizes high temperature flameless combustion technology which offers many benefits including being the most cost effective option for converting planet garbage into energy.

Plus the savings mount up when you consider UTOC emissions and carbon footprint are the lowest of thermal waste recycling alternatives.

Revenue/cost offsets from energy sales, tipping fees, and carbon credits result from UTOC conversion of biological and manufactured organic wastes into clean, >1300°C gas streams.  UTOC project simple payback durations (mostly between 2 and 10 years) qualify for private financing, eliminating ALL government (taxpayer) funding requirements.

UTOC replaces landfills using less than 5% of their footprint, thus saving valuable land.

We have a good waste management system. Why consider UTOC?

The questions to ask yourself are:
What is the levelized lifetime cost of a UTOC Energy From Waste plant?
No cost.  Short simple payback UTOC projects financed over their 30 year life generate monthly revenues/cost offsets the day they go into operation. 
Will your system achieve the UN's target for greenhouse gas reduction?
Multiple third party tests have shown ultra low UTOC system emissions to be well below the most stringent environmental limits.
Does your system responsibly protect the environment?
UTOC has a small footprint, consumes no resources, has ultra low emissions;  it helps clean up the planet.
UTOC is the most efficient and "greenest" option for addressing planet waste, clean water and sustainable energy urgencies.

What is the size of a UTOC system?

The footprint of a UTOC plant for a population of 530,000, processing ~1,000 tonnes per day (tpd) MSW and producing ~40MW/hour electricity plus ~70MW/hour heat plus ~66 tpd of ash, is approximately 3 hectares.

What is the expected lifespan of the UTOC?

The UTOC has an expected operation life of 30 years.

Are there any unusual hazards for personel?

None, as long as the system is operated in accordance with VOsPS Operating & Maintenance guidelines.
