First of all, there are many types of waste: municipal (household, commercial and demolition waste), hazardous (industrial), biomedical, electronic (e-waste), radioactive, etc. Waste management includes the collection, transport, valorization and disposal of these waste. More broadly, it includes any activity involved in the organization of waste management from production to final treatment.
The main principles of waste management are:
Waste management techniques include:
A landfill, sometimes referred to as a garbage dump, is a place where waste is generally stored on the ground. Landfills are the most common and cheapest method for waste disposal in the world.
Incineration of waste is a technique of transformation by the action of fire. Waste combustion can be used to produce electricity and heat, but also is an important source of air pollution.
Recycling is the physical reprocessing of old materials such as metals, plastics and e-waste - industrial or household - into new products. The type of material collected for recycling can vary depending on the city and country.
Composting is a process of conversion and recovery of organic matter into a stabilized, hygienic, soil-like product rich in humic compounds: the compost. Anaerobic digestion is a process similar to composting, that allows the treatment of organic waste and sludge by fermentation in the absence of oxygen.
The collection of household waste is usually done by means of garbage trucks, which go to each point of garbage production to collect garbage. There are also collection systems where a network centralizes waste, such as automated vacuum collection.
Energy recovery from waste, often called waste-to-energy, is the process converting non-recyclable waste materials into usable heat, fuel or electricity through combustion, anaerobic digestion, gasification, pyrolyzation, etc.
Each type of waste corresponds to a management process. To properly manage waste, pre-sorting is necessary. This sorting allows the separation of recyclable from non-recyclable waste, and subsequently the energy recovery.
Sustainable waste management is a key concept of the circular economy and offers many opportunities:
Waste management involves collecting, sorting, treating, recycling, and when properly facilitated providing a source of energy and resources. Therefore, it has a huge economic potential that needs to be leveraged by public and private entities.
Besides creating jobs, improved waste management leads to a better quality of life for local populations, by improving hygiene conditions and reducing health risks related to illegal dumping and inadequate garbage collection.
The main advantage of sustainable waste management is to lessen the impact on the environment, by improving air and water quality and contributing to the reduction of greenhouse gas emissions. Besides, reducing food waste also helps reduce the heavy environmental cost of producing more.
The first one while promoting recycling is to make sure both consumers and recyclers are protected from toxic and dangerous substances that can be found in waste.
2. High costs
Moreover, this cannot be seen as a short-term lucrative investment as it obviously requires a lot of money to implement sustainable waste management strategies.
3. Quality of recycled products
Downcycling, the recycling process that turns waste into products of inferior quality, can cause a problem regarding the quality of secondary products.
