The ASEAN member countries alone are producing whopping tons of solid waste, which amounts to about 100 million tons every year. Adding the other Southeast Asian countries, the total waste is almost 250 million. This is more than the amount of waste generated by the US, meaning there is need to address the issue as a global concern. Both the South East Asian countries and other environmental associations have established various approaches to deal with the waste management challenges.
Managing waste is a solution that is complex, and it incorporates more than 30 different industries. It includes collecting the waste, transporting, disposing of the garbage, sewage, and various waste materials. By definition, waste management is a process of processing solid waste and provides a wide variety of solutions that recycle items excluding putting the waste into the trash bins. Recycling refers to the process of making use of the materials as a resource, and very hotel in the South East Asia is currently mandated to participate in the waste management approaches. However, the process must be done in a safe and more efficient way.
Waste management is also known as waste disposal. It is an activity and action that is needed to manage waste right from its inception to the final disposal. There are specific regulations and monitoring ways based on the legal framework that also relates to guidance and recycling the waste. The typical methods of managing wastes are divided into several categories such as reduction and reuse, recycling, feeding animals, fermentation, composting, landfills, land application, and incineration. Most of these methods have been proposed by the ASEAN member states in order to minimize the number of disposable materials.
Methods of Waste Management
Given the many methods that can be used to manage solid waste, we are going to look at the most commonly used approaches that are applicable in small, medium and large hotel businesses.
A landfill is the most common way to dispose of waste nowadays. It entails burying waste into the ground or a designated piece of land that is monitored by a municipal council. Developing countries mostly use this kind of waste management method because it is a bit cheaper, and the amount of waste generated is not enormous to deserve other sophisticated and expensive methods. However, there are processes that are applied to reduce bad odor and harm of the waste before it is thrown into the ground.
In many South East Asian countries, this method is being discouraged by the ASEAN organization due to lack of enough space. This ensures that the minimal space available for landfills do not lead to contamination of the environment by the methane gases generated by the landfills. According to environmentalists, landfills are responsible for water and air pollution that can severely bring negative effects to the environment as well as harming the lives of animals and humans.
This is also known as combustion where the waste is burned at high temperatures to convert it to gaseous and residue products. The advantage of this method is the ability to reduce the amount of waste and also decreasing the space required for a landfill. This thermal treatment of waste uses the incinerators to convert the materials into steam, heat, gas, and ash. In the South East Asia, the countries lack adequate space for creating new landfills and therefore the incineration process is being considered as the best option.
Recycling and Recovery
Recovery is the process of making use of already discarded items. These items are processed in order to obtain the materials and then convert them into energy or another useful form such as electricity, fuel, or heat. Recycling, on the other hand, entails conversion of waste products into new materials that prevent energy consumption of other raw materials.
A garbage disposal is an electric unit that is used to dispose of soft food waste by grinding and flushing them down the drain. It has been one of the agendas of various environmental conservation meetings and forums all over the world. The new hotels in the Southeast Asian countries are being encouraged to use garbage disposal to dispose of their food waste products. This will reduce overloading the already limited number of landfills. Garbage disposals grind food stuff and mix with water, and then the liquid waste is flushed and directed into the sewer line through the main drain. More info on disposal mag.
