| ![]() Vermicomposting at Home Driving a diesel sedan in Delhi made me feel guilty. Reducing consumption didn’t make me feel any better so, started looking for options on how I could reduce my carbon footprint. Bought houseplants and one day while searching on how to care for houseplants found out about Vermicomposting. Dug a bit deeper and thought why not to start? It would reduce the guilt I was having as well as my contribution to filling up landfills. Vermi-Composting is nothing but composting with the help of worms. Now, you might be wondering what is the use and why when there is already door step garbage collection available? It is because it has many benefits, some of them I’ll mention here:
Time Required: It just takes 2 hours once to get started and once when the bin is full and compost is ready to be harvested. Even if you can’t spare time, almost all of us have domestic staff/keepers which do our household chores. They can do it for you, just teach them on how to do it. It’s a one time thing. To get started 2 dustbins are required - One for wet waste and another for dry waste. Wet Waste dustbin should have all the degradable materials such as fruit and vegetable peels, tea bags etc. Dry Bin should have materials which are non biodegradable such as plastic wrappers, packaging materials, etc. Where to get the worms from? Worms can be purchased from any local nursery, or any acquittance who does vermicomposting and can share these with you. Only few of them are required as they multiply rapidly. If you can’t get them from these sources then “Krishi Vigyan Kendra (KVK)” keeps them. Just locate the nearest KVK. They retail for Rs. 250/kg. Even agricultural universities stock them. How to make a home for them? Materials Required:
How to set it up
Items which can be put in the bin: Food scraps which contain SALT and CITRUS should be avoided. Scraps like fruit peels, vegetable peels, boiled vegetables, rice without SALT, tea/coffee filters/bags, paper with black ink, leaves, crushed egg shells. Even meat and other products can be put in but they attract rodents flies and other insects, so they are not recommended. Source: The Squirm Firm Fun Fact: Worms cannot harm humans in any form so there is no need to be afraid of them. They don’t have eyes or teeth so they cannot follow or bite you. ![]() Some mistakes which you may make: Overfeeding - Overfeeding is the most common cause of killing the worms. What actually happens is when you put in too much scraps which they can’t eat the scraps start to decompose and while it happens it raises the temperature of the bin and makes whole bin anaerobic. Feeding Salty/Lime Products - Never put in any product which contains salt so it is advisable to put in scraps which are natural and unprocessed like vegetable peels, fruit peels, tea/coffee bags etc. Sugar is acceptable but it may attract ants if not covered properly in bedding. Watering - The bin needs a certain level of moisture so watering is a must but it can be done after a few days, everyday is not required. My bin can sustain more than a week of water but I usually water it on weekend. A worm can eat half his weight in a day. So put the scraps according to the quantity you have. Result The final compost looks like tea - soft non-sticky and pure black. ![]() (Source: Google Images) I had put mango scraps in and from a kernel, this plant started. Seedling from kernel This is my bit of conserving environment and reducing waste from landfills which in some parts of our country are now as high as Qutub Minar. If some people start composting after reading my post at their homes, colonies, societies my purpose of writing this post is fulfilled. This is how we can contribute our bit to save the environment!

Senior - BHPian | ![]() Thanks a lot for sharing. We too have been doing composting for kitchen waste. Except for meat / bones, everything bio degradable goes into this. This is just our second (or third) batch. The best part, our garbage outgo has significantly reduced. Only plastic, cardboard and others goes out. It has a mesh thing from the inside that prevents flies coming close to it and surprisingly is odour free which means it can be kept indoors. It came with about 1/4th feed when we got it. Every time it gets full, we leave about 75% of the feed in the society garden and the remaining 25% acts like a catalyst for the next batch. A periodic mixing might be needed once every 2-3 days for best results. For a family of 3, takes us about 2-3 months to fill it up.

| ![]() Great to see the interest in composting waste right at the source I have been doing vermicomposting for 5 years. My setup is 2 large Concrete pots. The idea of having 2 is just to give nature enough time and volume to the whole process. I had great success with pure vermicomposting with Red Wrigglers. We are vegetarian so there was never an issue with meat waste. Things were working great. Then over a period of time I realized then a different set of worms have infested the waste bin. I keep the bin open and in my covered terrace so very good chance of something else getting attacked and making it a home. The composting was still working and I didn't want to tinker with nature. So i let the new worms stay and process the waste. Infact the speed of food getting processed had increased a lot with the new worms. On doing some research i found that I had 2 sets of guests. One was Black soldier fly (BSF) larve and another were Fig worms. Both are great at processing food at a much frantic pace than red wrigglers. Its a myth that you can't add cooked food to a worm bin. We add bread, rice, vegetable anything and everything that is a food waste (Except spoilt milk more on that later). All you have to do it drain out excess water and oil from the food. Say you have a stable bowl of potato vegetable, just soak it in water for 10 mins drain out the water and then throw it in. Soaking it in water is critical so that the oil and excess salt etc get thrown away in the kitchen drain and the organic matter goes into the bin. When adding cooked food add a handful of cocopeat or some other brown material to control the moisture. Too much moisture in the bin makes its anerobic and then it can start stinking. The secret to no smell is to keep the bin dry. But you still need moisture for the microorganism to survice and multiply. Its really easy to find the right balance and get best of both worlds. Once in a while I make it a point to add whey (water on top of Dahi) and diluted butter milk which add more beneficial bacteria to the bin and helps population of good bacteria. The key to composting is not thinking too much and doing as little as possible. Its like a passive investement. If you check the progress everyday you will feel nothing is happening. Check it only once a week and you realize that nature is working its magic. We usually cook moderate quantity and throw out almost nothing. So I never bothered about how to best process cooked food. But when we started using composting pits in our apartment complex people were not keen on seperating out meet and stale food etc from other things that can be put in vermicompost. So I started looking for other options. I read a lot of material on Anerobic composting. I think Bokashi composting is the answer to composting inhouse and that too with just a small container of a closed drum that can be easily kept under the kitchen sink. I didnt want to spend a lot on buying bokashi specific bucket so i experiemented and found a way that is works for me. Bokashi needs about 2-4 weeks for the waste to be processed by fungus and anerobic bacteria. Then at end of 2 weeks i just throw the bokashi composted waste into my normal compost bin. Since the materials have already broken down in bokashi it breaks down even faster in the worm bin. The good thing about Bokashi is that you can add any kind of food into it. Meat, Dairy anything and everything can be added. The key again is to not add too much liquid. The bokashi bucket needs to stay moist but not dripping wet. The food we throw away has enough moisture so there is never a need to add any water to bokashi. IMO Anyone with some spare space should start vermicomposting. Add to that people living in small apartments can definitely have a bokashi setup inhouse and then throw away the fermented stuff into a common composting pit every 2-3 weeks. This is best of both worlds. Last edited by freedom : 23rd August 2018 at 17:27. |

| ![]() This is a great thread considering we need to reduce our carbon footprint. Segregating waste and taking care of our own wet waste is a much needed step in our attempt to clean the environment. I have been composting for about 18 months. I use plastic bins from Greentechlife. This is an indoor composting setup which is aerobic (as opposed to anaerobic). Its very simple to do - actually takes up only 2-3 minutes daily. The first step is to segregate and keep aside our wet waste - vegetable & fruit peels, coffee grinds, tea leaves, leftover spoilt food, dairy, even non-veg (bones, fish, etc). This waste needs to be kept in an air-tight container so that it does not attract flies and insects. Segregating waste and keeping it in an air tight container: ![]() Once a day I empty this waste into the bin and add Bio Bloom Air which is a layering powder made of cocopeat charged with microbes. The bin (aerobic composting has a mesh on top for air): ![]() This is what it looks like from inside: ![]() Compost ready (about 30-45 days later): ![]() There is also a liquid that collects at the bottom which is extremely beneficial for plants. It can also be used as a drain cleaner because the microbes in it eat up all the muck. The cost of a two 20 litre bin set up (enough for a family of 4) is about Rs. 3000. Initial running cost (which is the cost of Bio Bloom Air powder) is about Rs. 250 a month. This cost gets reduced to Rs. 50 a month after 3-4 months since you can use your old compost to do the layering. So its quite fantastic and satisfying!! |
