  • Let me tell you beforehand, composting is very hard. There are mainly two kinds of composting methods according to the bacterial action. Aerobic and anaerobic. Aerobic compost is not dug but piled as a heap. This can be very smelly and can be inconvenient. You are supposed to turn the compost every three to four days. Generally turn your pile every time you feel the temperature is low. The hotter a pile is the faster as the reactions that were occurring. It could take up to a week or ten days for you to get the compost. And also you are supposed to layer the waste. Dried leaves and grass form a layer on which your garbage forms another layer. Keep this layering going to get composting quick and efficient. Make sure your layered pile is moist and the waste is nicely shred to increase the surface area of decomposition reaction.
    Anaerobic composting is harder and it releases methane which is very flammable. You could use regular bins that are covered by sacks with air holes to accomplish this composting or dedicate an area for piling waste.

    The stronger a light shines the darker are the shadows around it.

  • Many people are doing composting in their backyard or in the balconies near the flower pots. If you have interest in horticulture and you have flower plants in your house then your job becomes easier as the waste leaves and material from the plants is a very good liner for composting. You can buy a composting bin for this purpose or if you have some technical hand you yourself can make a one with some old tin container or big flower pot with a cardboard or plywood or metal sheet with a few holes in it to cover it as well as to keep in touch with limited air.

    This bin is to kept in a place where it gets some sunlight for at least a few hours everyday so that it gets the required heat for bacterial action.

    The bottom of the bin should be layered with dry leaves, grass etc from the plants and over it we should layer the waste from kitchen. Do not put plastic bag parts or paper pieces or metal pieces or other non degradable items in it. We have to sprinkle a little water to keep it wet. After a half inch layer of dry leaves etc we can layer 1-2 inch of kitchen waste and then again half inch of dry grass etc.

    Go on doing this layering till the bin is almost 3/4 th to its capacity and when it starts giving smell mix it upside down and if it appears dry sprinkle a little water time to time.

    Now do not mix new waste from kitchen to it and let it remain like that for 15-20 days and the initial composting is done. After this it is to be transferred to another bin where it will slowly decompose further to become almost a dry manure and after 2 -
    3 months it can be used as it is.

    Meanwhile the first bin can be filled with the recent waste and the cycle repeats.

    It will require some initial attention to keep the bin warm in sunlight and a little bit moist all the time but after a few cycles one can learn it.

    Knowledge is power.

  • The following items from the kitchen and house can be used for composting.
    All vegetable and fruit wastes,
    Anything made out of flour like Old bread, doughnuts, cookies, crackers, pizza crust, noodles etc.
    Cooked or uncooked grains like rice, barley.
    The left outs of coffee and tea powders after using for making coffee and tea.
    Fruit or vegetable pulp, Eggshells etc.

    Don't use the following for composting.
    Meat or meat waste, Fish or fish waste
    Dairy products, such as cheese, butter, cottage cheese, yoghurt, cream cheese, sour cream, etc.
    These items will cause the imbalance in the waste foods and break down slowly. They attract scavenging insects and animals. So it is advisable not to use these materials.

    The procedure:
    1. An open pile or a compost bin can be used, Bins are neat, animals can't reach easily and heat will be well preserved. The bins are readily available in the market. The size and type of bin can be based on the quantity of kitchen waste that will be generated.
    2. Select a location. It should be flat, well-drained and sunny. You should be able to reach easily.
    3. Initially, a layer of course materials to be kept in the bin to allow for drainage and aeration. Then cover this layer with leaves. Then simply alternate between layers of greens materials and browns. Browns are carbon-rich materials.
    4. All the kitchen compostable material is to be collected in a container. When this container is full add all the contents to the bin. You should see that the top layer should be browns.
    6. Whenever you are adding kitchen waste, mix it with the lower layers. Keep the material wet always. It should be like a wrung out sponge. Either water or dry material is to be added to keep the material at the correct level of moisture. Mix the compost once in a week to avoid foul odour and break down of the material.
    7. Finished compost will be dark, ductile and smell like earth. It may take four to six months for the compost to get ready. The compost e which is ready will be in the top. Remove the completed compost and leave the unfinished material in the bin. Never use unfinished compost which may harm the plants.

  • The author is interested in starting a vegetable garden in the terrace of his house. Simultaneously, he wants to convert the bio-waste produced in the house into bio- fertilizer. This is welcome thought. These days there are several options. In the above comments details regarding dry manure production are given. Windrow composting, vermin composting, pipe composting, bucket composting, etc. are different methods generally used.
    But there is another method, which converts the waste into biogas, which can be used for cooking. The slurry coming out of the tank can be used as a manure for vegetables. The same has to be diluted with water before applying. The bio gas coming out of the tank can be connected to a Stove (specifically made for this) and used as combustion fuel for cooking purposes. Thus biogas plant is an option to convert the waste into manure and fuel simultaneously. Details regarding Biogas plants are available on line or through search. Based on the amount of waste produced one has to select the appropriate size. Certain types of waste cannot be introduced into the plant which include onion, lemon, bone, etc.
