A biotechnology for aerobic conversion of food waste into organic fertilizer under controlled aeration, stirring, pH and temperature at 55–65°C, is proposed. To maintain neutral pH at the beginning of the bioconversion 5% CaCO 3 was added to the total solids of the food waste. The addition of 20% horticultural waste compost as a bulking agent to the food wastes (w.w./w.w.), improved the bioconversion and increased the stability of the final product. No starter culture was needed for aerobic bioconversion of food waste into organic fertilizer for 10 days. The low contents of heavy metals in the raw materials used in the bioconversions ensured the safety of fertilizer from food waste for application in agriculture. The addition of 4% organic fertilizer to the subsoil increased the yield and growth of Ipomoea aquatica(Kang Kong) by 1.5 to 2 times. The addition of phosphorus is required to enhance the positive effect of organic fertilizer on plant growth.
In just 3 hours, California Safe Soil turns fresh food waste into a liquid fertilizer which promises to boost yields, cut costs, and reduce water pollution in agriculture.
The amount of food wasted each day in just the US alone is enormous, and while we can all easily begin to do something about the food waste that we’re personally responsible for, addressing the huge volume of food waste at the institutional and business level is a much more challenging puzzle.
The majority of organic waste you have in your home can be made into a superb fertilizer which will be ideal for your garden and plants. Natural fertilizer is a great alternative to many artificial brands currently on the market. Creating compost is becoming more and more popular. The process is simple, quick and can allow you to create a large amount of fertilizer in a short space of time. .
Step One – Collect Household Waste
Think carefully about the food products you are throwing away and whether they can be beneficial to making a fertilizer. Avoid oils, grease, milk products and fatty meats because these will only serve to make your compost a slushy mess. The things you should be on the look out for are peelings from fruit and vegetables, nuts, eggshells and over-ripened fruit. Also, make sure you can get your hands on some wood ash as this helps the composting process. This will be easy if you have an open fireplace.
Step Two – Collect Garden Waste
Save all leaves and clippings from any gardening work you do. Nothing will make the fertilizer more productive than a healthy amount of natural waste. Consider laying the leaves and garden waste around your lawn before you cut the grass. As your lawnmower goes over the top, it will suck in the waste and mix it with grass cuttings. You can then empty the lawnmower onto your compost heap. Nearly all excess garden clippings can be put into the compost mix although it should ideally be added over a period of days for the ideal effect.
Step Three – Other Materials to Include
Another organic material you can include is sawdust. Piles of sawdust can accumulate if you have been sawing wood or you can purchase large bags of it from any good gardening store. If you have your own livestock, add some of the manure to the compost pile. You can buy this in small amounts from nearby farms or from other locations that keep animals.
Step Four – Create Compost
Place all of your compost materials into a compost barrel. This barrel should be slightly raised from the floor and should have a handle which you can turn to rotate the barrel and the compost. Spin the barrel at least two times per day. This will make all of the compost materials mix together and combine natural benefits to make a very effective fertilizer. Make sure the barrel has a couple of slits down the side to allow moisture to escape as the barrel is turned.
Step Five – Spread
Once your compost has turned into a dark and soil-like mixture, it is ready to be spread. Use a large garden fork to pick the compost up and throw it over areas you would like to fertilize. Do not be afraid to be generous but remember that the compost is only a growing aid. Allow the compost layer to seep in and take effect before you fork on another load.
