Different Drying Methods Used By Municipal Solid Waste Dryers

The amount of waste management will increase as a result of the rise in population. The high percentage of waste requires an improved way of waste management to keep the environment clean. However, the waste composition is different depending on the consumption patterns, economic development, and living standards of each state. The difference in composition has made drying companies use several drying methods depending on the structure of each waste. Here are some of them.

1 Biodrying

Biotechnology is a dying process that uses a combination of aeration and heat coming from natural organic matter to dry the waste. The process operates on the internal energy produced by the decomposed waste, and the biological issues released during the process include bacteria, fungi, cellulose degrades, and actinomycetes. As the process continues, the person operating the machine might add inoculation materials to the dryer to reduce water and remove excess water.

Many countries have adopted biotechnology because it is economical and environmentally friendly, and it can produce superior bio dried material at a minimum residence period. However, for the proper growth of microorganisms during the biotechnology process, the realtor should have the right temperature and the required aeration.

2. Biostabilization

Biostabilization is a process of enhanced biological degradation of organic matter to reduce environmental pollution. The process in this method is similar to the drying process, but the only difference is the preparation of materials to be filtered. Also, the time required for stabilization is longer than in the bio drying process.

With the use of innovative technology, the products produced in stabilization can be used for agricultural activities. Besides, the products can provide numerous economic advantages, including GHG emission reduction and efficient land space utilization.

3. Solar Drying

For years different people have used the sun and wind to preserve and dry varied foods. However, in the last decade, many countries decided to change their energy policies to reduce the importation of petroleum and started to use renewable energy. One of them is solar energy, which is beneficial to the environment because it is easy to utilize for renewable energy.

The solar dying takes place in a modular solar dryer, which aids in heating and air circulation. When dying different products, the dryer removes moisture according to the temperatures required for each crop. However, the drying amount per hour depends on the climate conditions of each area.

4. Thermal Drying

Thermal drying removes excess moisture using a large amount of which is transferred to the wet solid to evaporate the water. The process is, however, expansive and sometimes harmful to the environment because it produces a non-renewable energy resource.

When companies use drying ovens for the drying process, the products dry by evaporation through heat from currents. The ovens are favorable because they help to control the temperature and dry the products quickly. The short dehydration process is enabled by setting the right temperatures.

The world’s population is growing at an alarming rate, and so is the solid waste. The rise has prompted waste drying companies to adopt different waste management methods to keep the environment clean. The four methods above are some of the best practices that most countries have adopted for use for waste management.
