LG Is Developing a Waterless Washing Machine That Uses Carbon Dioxide Instead of Water

lg waterless washing machine

Traditional washing machines need a lot of water and detergent to clean a batch of dirty clothes. It usually leads to wastage of clean water and adds more pressure to the already-degrading environment. Citing this concern, LG has taken up the responsibility of developing a completely waterless washing machine for the commercial markets.

LG Waterless Washing Machine Details

According to recent reports, LG has started the development process of the waterless washing machine. The South Korean giant started working on the project through a regulatory sandbox program after the Ministry of Trade, Industry, and Energy approved the trial of the technology. The technology involves using carbon dioxide as a replacement for water in washing machines.

LG has apparently found a way to turn environmental carbon dioxide from its natural gas form into a liquid state by a refrigeration and compression process. After turning the gas into a liquid state, the LG waterless washing machine would be able to wash dirty clothes using no water or detergent at all.

As for taking out the pollutants from the dirty clothes, the washing machine will use the viscosity and the surface tension of the liquified carbon dioxide. After the washing process, the appliance will be able to convert the liquid CO2 into its original gas form and reuse it for the next wash.

Hence, there will be no discharge of any kind of gas or detergent-mixed water with the waterless washing machine from LG. This would save a lot of water that is currently being used in households to wash clothes.

As for the availability of the LG waterless washing machine, the company will set up the first unit at its research lab after the development process. It will operate the machine for two years to test its capabilities before making it commercially available in the market.

  1. Mungeri lal ke haseen sapne. Release of co2 will only add to climate change scenario, as co2 is said to be the main cause the climate change on Earth.

    1. Ary, it will absorb from the atmosphere and release back in the atmosphere. Where is the harm? Moreover they are saying the machine will keep it stored for the next cycle.

  2. Those who are suggesting other ways they should work on instead of this. They can only work on something attainable not something impossible that you rant out of your mouth and tell them to make it happen.

  3. Using carbon dioxide: Good thoughts but product may become expensive and changing one’s mind set regarding water less washing would take time to sink in.

    if any washing machine company could come up with a solution to recycle the soap/ rinsing water at an affordable cost, it would reduce water usage by 1/3rd, which would be a major drive in preserving water consumption. Hopefully some one comes up in this concept too..

  4. These companies should instead develop a technology for household that would purify the used water from washing machine & other sources in house & reuse it to save water

  5. Refrigeration again contributes to the greenhouse effect. And what about the power consumption this washing machine will require? The idea sounds good, but is it sustainable in a true sense?

  6. They could have some technology to do the same with water without detergents and recycle the same water for washing purpose

  7. Great idea! If the proof of concept stage is passed then it’s question of time for overcoming challenge in making our commercially viable. Those who developed this deserve Noble price.

  8. Lg gives the best technology in washing machines and this technology help to reduce water wastage and eco friendly also this is verygood idea to next level washing experience

  9. Do you know the cost of liquid CO2? They sell it for soda machines. Not only they will charge a fortune for the “cutting edge” “state of the art” “pioneer” and what not ๐Ÿ˜‚๐Ÿคฃ๐Ÿ˜‚๐Ÿคฃ machine on top one has to get this ere liquid CO2 from somewhere (of course it is not as easily available as Surf Ariel Henko bla bla). I guess will be just a advertisement object.

  10. Sounds good but the technic is still not clear with respect to cost efficiency.๐Ÿค”

  11. Great revolutionary work. However what is the need for converting liquid CO2 to gas after the wash and again back to liquid for the next wash. So much conversion energy can be saved by just cleaning and storing the liquid CO2 appropriately.

    1. Abe 5th fail. CO2 is volatile in liquid state and hence will convert immediately into gas. Thats the reason why your cold drink taste like sweetened water after few hours

    2. Maintaining the CO2 in liquid form is more power consuming. Need to keep the temperature low for extended period of time

  12. Very good invention. Kudos to our scientists I am very happy for the nature & mother earth with less pollution

    1. Refrigeratoin. The halocarbons in refrigeration appliances contribute to the greenhouse effect. These gases prevent heat escaping from the earth and deplete the ozone layer that filters the sun’s rays. The greenhouse effect and ozone layer depletion contribute to global warming.

  13. Amazing innovation from LG. Hope it comes in retail market soon…all my products are from LG. #happycustomer

  14. Water leakage is not harmful. But carbon dioxide leak could lead to asphyxiation depending on location of machine within house. Also operating pressures may increase leading to safety hazard.

      1. He probably is not. Carbon Dioxide is very dangerous if released in large amounts indoors as it can cause asphyxiation as the poster suggested. This is a well known danger in modern data centers where CO2 is used as a fire extinguisher instead of water – which otherwise would wreck the equipment.

      1. No. See Pubmed carbon dioxide poisoning. It can cause tachycardia, convulsions, unconsciousness and death at concentrations > 10 %. It seems there will need to be adequate air exchange in case of system leakage.

  15. This looks promising but given the population and usability, it may take decades even after its development.
    All the best to the team , making life good to better…God Bless

  16. CO2 is very harmful for all living organisms. How will you prevent it from leaking into the laundry room.?

  17. Compressing CO2 to liquid state (~ minus 70degC). & storage requires refrigeration, so it’s not low in power consumption. The technology of CO2 cleaning is used in metal surfaces which withstand temperatures however specially lower temperature withstanding capabilities of synthetic clothing yarn (& not damaging them ) requires demonstration

  18. This is crazy, the compressors, and condensers need will ear up ton of energy, not to mention the lubricant need is also a pollutant

  19. Definately it’s a eco friendly waterless washing machine. If it is come into existence, it will join to weep the pollution through this CO2 liquid washing machine invention.

  20. Waw. Completely out of the box thinking.
    If it gets to reality, it will be a huge breakthrough on laundry industry

  21. Cleaning depends on solubility of dirt in liquid carbon dioxide, colors may also washed-out. ๐Ÿค”

  22. Where do the contaminates on the clothes go?
    Dirty clothes in…..clean clothes out…..where’s the dirty at?

    1. I’m guessing the liquid CO2 with the dirt will pass through some sort of filter which will need replacement after a few cycles of wash. Can’t think of any other way.

    1. Thank goodness at least one person is appreciative of the news. Rest are like the ostriches with their head buried in the sand. Unwilling to believe that there can be any out of the box solution.
