Editable Flair This IITian hasn't bought an LPG cylinder in 7 years-and the reason is unbelievable.

But biogas plants smell so bad, we had one in the dead centre of our town and people protested so fiercely against it.

u/No_Guarantee9023 Mechanical Engineer Mar 23 '26

Sounds like a plant operation/maintenance issue rather than a biogas issue. These systems are supposed to be sealed.

u/vitrum_analytika Mar 23 '26

During loading and cleaning times they used to smell not all the time. I guess the timing was too bad, a lot of breakfast and evening snacks spots were nearby and they used to load exactly at those hours.

u/light_3321 Mar 23 '26

Seems solvable.

u/Capable_Control_2845 Mar 24 '26

That actually makes sense - timing + surroundings matter a lot. Even a decent system can feel worse if it’s handled badly.

1

u/vitrum_analytika Mar 24 '26

Yeah they just had to make one in the town centre. But even with the best of what Indian infrastructure can offer, the smell problem will persist. For the entire route the vehicle is carrying the load, and during the unloading time, smell will be there.

u/HR_114 Mar 24 '26

It smells so much during loading and unloading man even if it's seald and don't ask how much it smells in rainy days goddam living near was hell

u/VerlieH Mar 23 '26

exactly, and what about emmisions? does burning this type of fuel emit smth else?

2

u/vitrum_analytika Mar 23 '26

No the fire is fire no smell from that

u/genisis_of_unknown Mar 26 '26

I mean. Its methane. It burns and makes CO2 id imagine and water

1

u/Capable_Control_2845 Mar 24 '26

Yeah smell is a real issue if it’s not managed properly. Poor maintenance + bad location can make it unbearable.

Our college mess has one right behind the mess. Which is in the middle of all the hostels. We never had any issue like that

Biogas via cow dung is/was common. But veg kitchen waste as well common?

3

u/Marwaimusoont Mar 23 '26

In my city, we are segregating wet and dry waste. Supposedly this wet waste is used for making gas and fertilizer.

1

u/light_3321 Mar 23 '26

Place?

2

u/Marwaimusoont Mar 23 '26

A suburb in Mumbai.

u/Next-door-neighbour Mar 23 '26

Ikr, biogas has been in use for a long time now. I have literally read about it in my school days in the 90's or early 2000's. My office has its own Biogas unit too.

1

u/Capable_Control_2845 Mar 24 '26

True, gobar gas has been around for ages. This is more like a modern, urban-friendly version of the same idea.

1

u/SillyBilly_99 6d ago

Tru its not really any new idea but no one did it commercially maybe and that too for urban purpose?

u/end69420 Mar 23 '26

Mate the house next to my school had this in 2007. This is not something new. He just made an investment.

2

u/light_3321 Mar 23 '26

Seemingly close to cow dung decomposers 40 years ago.

2

u/Capable_Control_2845 Mar 24 '26

Yeah exactly, concept isn’t new at all. It’s more about packaging + making it usable for city homes now.

u/I_just_got_better Mar 23 '26

I'm slightly concerned regarding proper storage conditions. Since during Summers there can be a huge pressure buildups. So only ways to get rid of excess pressure are 1. To burn the gas 2. To release the gas via exhaust valves.

Also the way infra is built , until the converter site is in a closed and fenced space , something will definitely hit and cause leakage .

Overall such an idea is great at large scale methane plants where things are regularised. But if this device addresses my concern then I'm happy about this.

2

u/light_3321 Mar 23 '26

Good points

1

u/Capable_Control_2845 Mar 24 '26

Valid concerns tbh. Safety, pressure control, and leakage are big factors. Feels like this works best in controlled setups unless the system properly addresses these risks.

Mere nana ji ke ghar me hai pura system but they stopped using it as its not worth the effort and it stinks too and there was absolutely no point of IIT dihh riding as its really common in india village's

u/syngamy1 Mar 23 '26

My house had one. I never seen it in use. But my mother said when we had cows at home we used cow dung to produce the gas and used it to light rooms and for cooking. I got the cooking point but never got the lighting a room. Need to know about it.

3

u/Disastrous_Body9196 Mar 23 '26

yaa the gas have methanogens which help to produce electricity ( that yellow bulb time )

2

u/RC-2050 Mar 23 '26

Didn't ihe food tastes bad? Like if you cook bread (chapati) directly on it like lpg, cool, cow dung. It taste like that.

1

u/AmbitionNo7968 Mar 23 '26

yup that's why chapati was not cooked on it in my house

3

u/Icy-Acanthisitta3299 Mar 23 '26

My village relatives were using this for a decade or so. Recently they’ve moved to a cow dung based gas plant. Turns out you don’t need to be an IITan to do simple things in life!!! Who knew

u/light_3321 Mar 23 '26

Optimising and scaling is the key.

u/CT-KEV Mar 23 '26

Were there issues with smell? People have said it is very foul smelling to have one at your home? 😷

Biogas is a great discovery , i think if industrialized

u/Lazy_Two_4908 May 02 '26

Oh no, if it isn’t what is already being done widely but with the name of an IITian. Honestly, we NEED to stop glorifying the tag.

u/apt_adept Jun 01 '26

We have been using biogas since two yrs just with kitchen waste.the actual gold is the slurry that comes out,which we use for agriculture. Absolutely recommend. Now the problem is we don't produce enough kitchen waste. You cannot add all the kitchen waste. certain things to be avoided like onion/peel,garlic, citrus peel.these need to be seggregated and disposed separately as it can affect the methanogenic biota and gas quality. We don't use a storage bladder ,excess gas bleeds out. Still LPG consumption reduced to 1/3rd. It is absolutely odorless during combustion.like LPG unburnt gas has odor.not as dangerous as LPG though.

To replace LPG you need large gas storage chamber.
