The world is struggling to act on the climate impact via various new standards and

regulations. While the USA declined participation under the Trump administration, the

new Biden one will continue to push the climate impact situation. One of the critical

issues is the Circular Economy system to reduce waste. The electricity solution although

100% clean on pollution, will turn into a major waste problem of critical magnitude with

the waste of batteries.

The current renewable energy solutions are ONLY Sun and Wind. Both these systems are

still struggling to find economical energy storage, to be able to provide 24/7 service. The

PV panels, once exhausting their lifetime will also create a major waste problem.

The biggest Climate Impact problem is, by far, the world waste processing one. For

various reasons the WASTE to ENERGY (W2E) has not taken off. This market segment

has yet to show a successful approach and gain back the trust of governments and



We would like to offer NEW PARGDIME approach to these issues.

W2E (Heat Based)

We would like offer a NEW APPROACH to climate impact issue, based on TOTAL waste

processing, ZERO WASTE, Circular Economy and distributed energy. This new approach

does not need to REPLACE solar and wind but merely complement them into 24/7 energy

supply, with no storage utilizing expensive electricity storage schemes.

Actually, the proposed approach is simple, easy to use and extremely environmentally


The circular economy’s first stage is the TOTAL all waste processing. (except hazardous

and C&D). The ability to perform a compete processing scheme at ZERO WASTE to

landfills, solves the current major waste problem. This ability eliminates the need for

source recycling and waste separation, which solves the multi-bin and recycling “cages”. It

is back to the ONE BIN solution. This is a great positive impact on the environment by

cleaning the sidewalks from recycling bins, and dramatically reduces the number of

vehicles to collect the waste.

Once ALL waste is processed, the second stage is turning it into clean energy. The major

reason for the current W2E failure, is the inability to produce even caloric value SinGas to

operate gas engines and turbines. The new approach actually utilizes HEAT as the energy

source and eliminates most of the gas operation and pollution problems.

The new approach to energy based on Heat, does not interfere with the quest for cleaner

power supply, but rather provides clean power for most of the energy uses. The major

advantage of Heat is ZERO pollution.

The HEAT approach also helps in distributing power to the user’s source: (Communities,

Hospitals, Hotels, Industry, Airports, Seaports & Railways).

The power utilization analysis for most customers, shows that only 25%-30% of the

electricity is actually used for lights and motors. The rest (70%-75%) is used to produce

HEAT based services such as HVAC, hot water, steam and water purification

(desalination). Each power generating equipment produces approximately 1.5 MW/heat

for every MW electricity. This phenomenon helps in reducing the actual power generation

and utilizing the access heat for the other uses. It also eliminates the need for cooling

down systems and provides higher efficiencies.

So, what are the real advantages of this new PARADIGME CHANGE:

1. Solving the worlds waste processing problem.

2. Producing clean energy (Hot Air).

3. Providing distributed energy supply via microgrids. (eliminating large power

generating units and high voltage grids).

4. Eliminating the use of GAS based HVAC by utilizing absorption systems.

5. Dramatically reduce the price per KW/H to the consumers.


6. New technologies of organic waste processing, to supply clean Jet Fuel instead of

Bio-Jet fuel. Saving the airline industry $$$$.

7. Reducing the cost of operation of Hotels, Hospitals, Airports and Seaports.

8. A new unique approach to railway operations, eliminating the use of diesel power

and reduces dramatically the pollution.


The pursue of W2E based on circular Economy, Zero Waste and especially utilizing HEAT

as the fuel source establishes the company as a leader in the social and climate impact.

The social impact is based on activities performed in country and providing many

additional jobs at all levels. Furthermore, it enables the upgrade of the local industries in

both technology and management.

The Climate Impact is even more dramatical. The system being TOTALLY clean provides

eligibility for both Green funding and Carbon Credits. It is the fastest response to Carbon

Neutral society.

The current approach to renewables based on solar and wind is yet to be perfected.

Combining these with W2E based on heat solves the interruptible power supply and

provides clean 24/7 power generation.

Finally, the various advanced applications have a major impact on many aspects of the

day to day life. From Hospitals to Airports, Railways and Maritime this new approach

provides a very high impact.

It is time for the world climate impact people to start thinking “outside the box” and adapt

new approaches to reduce pollution.

W2E as energy storage

The world Climate Impact society is looking to replace the use of fossil-based energy with

renewables. However, the concept is that renewables are solar-based and wind-based


The major setback of these solutions is the intermittent power supply. Since the power

(electricity) generation is currently moving from large generation units to smaller local

supply systems eliminating long haul grid traffic, the current solution posses a serious

problem for the continuous power supply.

The acceptable solution is storage. However, physics is preventing the reduction of

storage costs which makes it less economical.

For some odd reason NO ONE is looking at W2E as a solution.

Well, the reason was that W2E, until now, had major problems and thus was not playing a

role in the storage market.


There is however, a new approach to the problem. It is a HYBRID W2E System based on:

ALL Waste processing, Zero waste to landfills, Hot Air based gasification and distributed

power generation via microgrids.

This same system can be installed a supplement to the renewable systems and provide the

necessary power gaps at a very competitive price. Moreover, it solves the major problem

of Waste Processing and eliminates major problems such landfills and waste separation at

the source.

Reducing the cost to the municipalities for waste processing and eliminating vast

Methane pollution from landfills and providing continuous power generation at the


Large power generating wind and solar systems are costly operations especially since it

needs large grid infrastructures and very sophisticated power control systems.

The patented use of hot air as fuel of the EFGT turbines (External Fired Gas Turbine), is

capable of quick start and stop and can be used as the power supply equilibrium at a

fraction of the storage prices.

Batteries of all sorts pose a major waste problem once they have exhausted their service.

It is time to wake up to a new Circular Economy based system that reduces pollution,

solves serious waste problems and generates clean energy for all.

Is there an ideal size of a project that would be optimal for W2E? I imagine that too small and the scale/footprint simply wouldn't be feasible?
