All natural environments have a carrying capacity. Whenever the carrying capacity is exceeded there is a strain on the environment. This strain is manifested in a number of ways, such as overpopulation or over consumption. Both of these activities result in the creation of waste. Waste that is increasing in quantity day by day. A lot of which is non biodegradable. This process has been continuing for a long time now, but in the last decade the amount of waste produced has increased exponentially. This has a direct bearing on our environment and creates health hazards for us all.
Apart from reducing the usage of non biodegradable materials such as plastic, we must ensure that biodegradable waste is treated properly, instead of just being dumped untreated.
Traditionally, most of our waste is either incinerated or it is dumped in landfills. Both of these have many adverse environmental effects. Incineration creates a number of harmful gases, which apart from adding to pollution, adds to the green house gas content, which furthers global warming and climate change. Not to mention, the harmful gases produced are bad for human health. Landfills on the other hand, are quickly getting filled and we are running out of space to dump our waste.
The leachate from landfills percolates into the soil and into the groundwater, polluting both. Given these dire consequences, it is of utmost importance to switch to safer and more environment friendly ways of getting rid of our waste. This is where composting comes in.
Composting is a process of wet waste disposal where organic waste such as food stuffs are decomposed through the use of microorganisms. Organic waste composter works to ensure that the perfect circumstances to hasten the decomposition are created. The end result is a return of nutrients to the soil, which enriches it and helps plants grow better. The composted waste can be used to create bio fuel as well as manure. This turns waste into money, as the products created can be sold further, thus providing another initiative to do take this up.
Composting can either be done naturally or an Organic waste composter may be used. An organic waste composter is an independent unit that takes care of the whole process of composting. It is fed waste and it gives you the end result in the form of manure or bio fuel. However, the process of composting, whether you are using an organic waste composter or not, are quite similar. Let us take a closer look.
There are basically two types of microorganisms that have a part to play in this process. They are called aerobic and anaerobic. Bacteria that requires oxygen are called aerobic and the ones that do not require oxygen are called anaerobic. Majority of the microorganisms that take part in the process are bacteria, though a certain percentage of them are fungi too. In addition to microbes, worms also play an important part in the process by helping break down the food.
Before composting, the waste can be shredded, using a shredder, to reduce the volume of the waste so that it can decompose faster, and can even be transported easily if the need arises. We at Earth Care Equipments manufacture the Kwik Shredder to help out with this process. Once the waste has been segregated and/or shredded, the composting can begin. There are typically three stages of the process.
In the first stage, the mesophilic microorganisms begin to break down the waste that is biodegradable. As they do so, the temperature rises, as heat is a natural result of this process and soon the temperatures reach upwards of 40 degrees. This stage lasts a couple of days. Once the mesophilic microorganisms are done, microorganisms that exist in the heat, that are thermophilic in nature take over and start working on the waste. They break down the waste further and the higher temperature acts as an ideal environment for the breaking down of complex compounds in the waste.
This process may last up to a couple of months. However, it must be borne in mind that during this phase the temperatures rise a lot, and if due care is not taken, the resultant heat may damage the very microorganisms that facilitate this process. To avoid doing this, several techniques such as turning the waste periodically in order to air it out, are adopted.
Once all the complex compounds have been broken down, the mesophilic microorganisms return to convert the remaining waste to humus, which can be used.
One must keep in mind that the ratio between the carbon and between the nitrogen must be maintained when waste is composted. If there is a lot of carbon, the composting will take longer and if there is too much nitrogen, the process will emit a foul smell. Other important factors include the moisture content and the oxygen content in the pile. All of these factors must be borne in mind when composting. Often, composting manually can be a tricky process. One may therefore, consider the use of Organic waste composter.
Organic waste Composter, such as the ones manufactured by Earth Care Equipments are fully automatic. They are self sufficient independent units where the waste can be put and the unit takes care of the entire process. For instance, the RTCT or the Re-engineered Traditional Composting Technology can dispose of 5MT to 25MT of waste in an environment friendly way. It takes care of shredding, mixing, and composting. In addition, it also treats leachates and stale gases before the final product is released.
We also have smaller organic waste composters that deal with waste starting from 30 kilograms per day going up to 2000 kilograms per day. We have serviced many large scale clients such as hospitals. Our products have been recommended by the Ministry of Environment and Forest as well.
Composting is integral to our waste management needs and it is an urgent issue that needs to be addressed immediately. The use of Organic Waste Composter to automate and hasten the process of composting is a step in the right direction. The sooner we adopt it, the better are our chances of controlling waste related pollution.
