Fully automatic composting machines: Let the buyer beware


Just Google “fully automatic composting machines”, a number of companies making out-of-the-world claims pop up instantly. Among them, “composting in 24 hours” is the most common.

I have been approached by a few vendors in Bengaluru to write about their products as a community composting method. When I met them, each vendor made different claims although all of them ran on similar technology. Some had sophisticated temperature display panels and the rest were basic. The shapes and sizes varied, too. But all of them seemed to consume power and let out CO2 intensely. Interestingly, none of the vendors buckled when I pressured them to get compost samples tested. They politely said they would, but never came back. Secondly, none of them came up with carbon emission analysis either.

Composting in 24 hours?

Please refer to this post on how composting happens. Composting is a process that progresses in stages and at each stage, certain types of microbes enter the pile and work their magic on it. Can all this happen in 24 hours, flat?

The claims

When I grilled a vendor, he claimed that they have imported “special microbes” from Canada. What does that mean? These particular microbes are not present in the Indian soil? Or, are these typically those that survive at sub-zero conditions but become suddenly hyperactive in a hot region?

I have been told that this ‘process’ doesn’t need a shredder as the machine itself will take care of it inside. In fact, even thick branches get ‘composted’ in 24 hours. How does that happen? A vendor replied that the temperature goes up and helps break down the material completely. As already discussed, only extremophiles survive at 122°C. Does that mean these machines are loaded with only extremophiles? If yes, then who will fill in for fungi and actinomycetes?

One vendor also claimed that these microbes can survive without food for one year. Now that’s another claim one should be wary about.

Is it compost or burnt carbon?

When I cross-checked all these findings with an expert, he said that “what comes out of these machines is not compost, but burnt carbon”. Since he has also been promoting his own composting system, he didn’t want to be quoted for obvious reasons. However, he regretted how government authorities are falling for these claims and letting such machines hit the market without due diligence. More importantly, he was concerned about the wrecked-up electrical conductivity of such ‘compost’ which can damage the soil composition and kill the plants.

Test reveals “zero” microbes

SAVITHA AP6215The above corroboration of facts was the final nail. But still, taking refuge in a laboratory test seemed sensible. I teamed up with compost expert Vani Murthy and her team-mate Shyamala Suresh and got a sample from one such machine tested. When the microbial load turned out to be “zero”, it answered all the doubts. Compost with zero microbes?

I sincerely hope that the vendors come out clean on this particular claim and tell what it exactly is instead of passing it off as “nutritious compost”. Those who still want may buy the product. But those who are genuinely in need of quality compost can look for other options.

Moreover, these machines consume huge amounts of power and emit CO2, thereby defeating the very purpose of reducing carbon footprint as far as solid waste management goes. The entire philosophy behind supporting sustainable solutions is rooted in the fact that our own so-called solutions should not boomerang on us and trigger a new set of problems. But that doesn’t seem to be the case with this.

Every credibility gap is a gullibility fill

This line rings so true in this context! The stinking garbage piles are reaching new heights, so is the mad rush for finding solutions. Those that promise fast results catch our attention but we refuse to ask even basic questions.

One may argue that it’s better than sending the wet waste to landfills. But that’s not a rational explanation to the crisis at hand. In fact, the genesis of landfill crisis all over the world lies in the “out of sight, out of mind” attitude. If we are ready look at these automatic composters as a solution, we should also be content with incinerators at every road curve. They will ‘solve’ the landfill crisis in a few weeks, won’t they?

The only way to prevent more vendors from jumping on to this ‘24-hour compost’ bandwagon is to reject quick-fixes and look for sustainable composting options. There are quite a few that suit your budget, space and other constraints.

Let’s compost responsibly. That’s the only way forward.

I request all the discerning readers and experts to forward their thoughts and comments (for or against) towards a constructive discussion on these fully automatic composting machines. Please present your thoughts with proper data in case you disagree with my findings and interpretations presented here. Thank you.

  3. People should realize composting naturally is the best method, which is obviously a time taking one. The wait and hard work is worth.. Patience is Virtue!! Thanks a lot Savita madam and Vani ji for creating the best possible awareness by doing all the ground work, take all the pain and teach us.

  5. Thanks for putting in the effort to bust these scams-in-the-making. More strength to the likes of you. These fraudsters are cashing in on people’s good intentions/guilt. I hope there is some kind of audit process to eliminate fraudsters from the genuine solutions. I’ll share this post on my social media channels.

  7. Savitha Mam,
    That’s an enlighting post by you. HoweverI I wounder it’s not just households that are falling prey to these claims but so are many corporates in their swanky offices. I had an opportunity to see some of the big corporates composting facilities in bangalore and was left wondering is this also a compost. I feel it’s high time there is awareness created to people on composting and the simple (complex for many) mechanism involved. I would rather look at Cow dung slurry as a inoculate rather then costly cultured microbial consortia developed in labs as a start. The shredding and mixing done in mechanised systems can easily be done with some manual effort.
    Common man falling prey is one part but governments and corporates falling prey to these claims calls for some high level of awareness creation.
    Regards,
    Ajay

    • You are right, Ajay. It’s disappointing to see such products getting approved and entering the market. I also agree with your love to work with cow dung but let me tell you, it’s not easily available in all areas of Bangalore. Moreover, we will be pushing it too far if we pressure people to use only dung as an inoculant. There’s nothing wrong in using lab-produced inoculants so long as it does not subvert the principles of nature. Expediting the whole composting process becomes inevitable as space is a major constraint. But this particular one cannot be called a ‘solution’ as it does not stick to any basic rules of composting.
      Thanks for your comment. 🙂

  8. Savitha, the write up is very informative and with sufficient fore-warnings. At Sovereign Park, as you have seen, we are very happy with the simple and efficient process installed by Sudh-Labh. No power needed and no C-footprints. No hurry either. The normal natural conversion takes 10-12 weeks to start off and thereafter compost output depends on the rate of loading the digestor. We are 40 apartments and no wet waste has gone out of the premises since Sept. 2014. We are using the compost in our own garden till now. There may be similar simple alternatives, sans powered equipments and accelarators. People should think in totality, discuss with the experienced, visit and see working sites and decide. Arise, awake and appreciate !

    • Hi Gopinath,
      We have 171 flats, would like to go for waste management. I too contacted by several vendors for 24 hours magic (cost varies from 4.5 Lakhs to 12 lakhs depends upon the size), But After seeing you post, would like to go for normal natural conversion. I would like to discuss with you further, Can you drop a mail to me: murugaraj.s@gmail.com

  10. Dear Madam,
    Request to please give your comment on ECOMAN’S Waste Management System ” FOODIE”, who have supplied equipment to various instityutions and hotels which convert Waste to Manure within 24 hours and cost of such machine for 1TPD waste is approx 35 lakhs INR. Even they produced Compost test certificate certified by Goa Pollution Control Board. I am really surprised how the waste will be converted to manure within 24 hours.They say in their brochure ” high technology which naturally converts waste to compost within 24 hours by using special micro organisms developmed through advanced bio-technology. They say their special microorganisms thrive in high temperature and effective in highly acidic and salty conditions. Please clarify me technically to have better clarity.

    • Mr Parameshwar, Whether it is Ecoman/Foodie or any other, I request you to pull out a little sample out of the ‘compost’ lot coming out of one such machine and get it tested at a good material testing lab. Please do not depend on the reports produced by the vendors, no matter where they got it done from. I request you to do some research on your own and talk to scientists, eco activists you know. What I am not able to understand is people’s urge to buy this machine which comes at lakhs of rupees just as they would buy an instant coffee maker. Please think this through. I am sure your test report won’t be different from the one I have put up here. Once you have it in your hand, I request you create awareness among people/potential buyers.

      Thank you.

  11. Dear Ms. Savitha Hiremath, we recently started marketing these Quick Composting machines in the Middle East and the response is good. I was not aware of these points you had raised. Is it possible to meet and discuss this issue personally? I will be in Mumbai on 12th November. Regards. Viren Narkar

  12. Hi ,

    Read your page on Fully Automatic Composting Machine , quite informative . No fully automatic composting manufacturer are ready to discuss on the quality of compost .

    Priorities are different for Organic Waste disposal ;
    ” Waste disposal because of Govt. pressure ” ,
    ” Compost manufacturing & quality ” ,
    ” To reduce cost of handling & disposal ” ,
    ” Non availability of land for sustainable disposal ” ,
    ” Lack of awareness or pressure from society ” .
    ” Compromise on quality of compost for fancy looking product ” .
    ” Use of fancy looking OWC m/c as a show piece ” .

    How to select right product for ” Composting of Organic Waste ” in green & sustainable way .

    • Thanks for your detailed inputs. Some vendors also produce regular compost, get it tested and pass it off as a testimonial to their own instant compost. Customers must do their homework before buying such machines. Regards.

  13. Hi Savita ,

    Did you ever sent compost ( as claimed by automatic OWC machine manufacturer ) generated from any automatic OWC machine , to any govt. approved lab for their quality check . Few manufacturers are not only adopting wrong practices to reduce volume of organic waste but their cost of conversion also is very high. Power consumption is huge , adds CO2 to environment and increases carbon economy .

    Area of least importance and Lack of awareness are making institutions , organisations to pay huge amount in the name of faster relief from organic waste .Actual process and output compost quality should be highlighted and shared with concerned and interested individuals, organizations , institutions & Govt. authorities

    Probable user dept. / institutions / NGOs should try the machines and get output quality checked in govt. certified lab. before ordering the same. Regards,
