What is the nature of waste produced?

Waste sorting

Collection is the collection of waste conditioned by the generator to be routed by the appropriate means of transport to a transfer station, a treatment unit or a final disposal site.[1] Two types of collection can be distinguished: general collection and selective collection:

Transportation consists of the trips to which household waste is subjected from where it is generated to the treatment points or transfer plants. Transportation must be carried out in authorized and properly prepared vehicles to ensure that the waste is not dispersed in the environment.[7] Some of these are:

A household solid waste transfer station, is defined as the set of equipment and facilities where the transshipment of such waste is carried out, from collection vehicles to large tonnage cargo vehicles, to transport it to the final destination sites. The fundamental objective of a transfer station is to increase the overall efficiency of waste management services, through the savings achieved by reducing the overall cost of handling, as well as by reducing transportation times and the intensive use of equipment and human resources.[8] The transfer station is also used for the transportation of waste to the final destination site, where it is transported to the final destination.

Types of waste produced by humans

A material that has already done its job or fulfilled its mission is discarded as waste. Thus, a waste becomes useless and of no economic value to most people. This waste can be disposed of in landfills or landfill, or it can be recycled for reuse.In this EcologyGreen article we talk specifically about one type of waste: solid waste. Read on and find out what solid waste is and how it is classified for proper disposal.

Once collected, the destinations of solid waste for disposal can be:Landfill disposalLandfill is a method of disposal of solid waste that consists of depositing it on the ground, in a spread out and compacted form. This is mostly done with hazardous waste.IncinerationA waste incinerator is a system for treating garbage that consists of burning this waste at high temperatures, which reduces its volume by up to 90% and its weight by 75%. The disadvantage of this system is that it generates ashes, inert residues and gases that can be toxic to people.Separation and utilizationThis system classifies solid waste at the place where it is produced and then recovers it. To recover them, processes, techniques and operations are applied to give back to these materials the possibility of reusing them in their original function or some similar one.You can learn more about this waste in this other EcologíaVerde article on How to treat household solid waste.

Hazardous waste

Improper waste management has negative impacts. On the one hand it can affect health, in the form of diseases; or it can also have detrimental effects on the environment: on the aesthetics of cities, natural landscapes and their species, and on the contamination of water, soil and air. All of these affect our quality of life.

“A waste is a substance or an object that its generator discards or has the intention or obligation to discard according to current regulations”. This is how the Law for the Promotion of Recycling and Extended Producer Responsibility defines it.

With respect to their risk, hazardous waste is classified as waste that may be waste or a mixture of waste that presents health risks and/or adverse effects on the environment. They also have characteristics of corrosiveness, reactivity, toxicity and flammability.

The correct disposal of waste is essential to avoid its negative impact on the environment. Especially when dealing with hazardous waste, what are the consequences of poor waste management?

Solid waste examples

The final disposal of waste in an uncontrolled manner or its lack or incorrect collection generates open dumps. Among these, the most risky are those where waste is systematically and indiscriminately dumped in streams or abandoned or uncontrolled or unprotected spaces, intentionally burned as a way to reduce its volume or by self-combustion and left for different actors to distribute its polluting load.

Pon points out that there are examples of several countries, including Chile, that have implemented policies to improve producer responsibility in specific areas such as “batteries, fluorescent bulbs, batteries, tires, packaging”.

Contrary to most of the available examples – hence the unconventional nature – La Pintana began its management program with the separation of organic waste (fruit, vegetables and pruning waste), based on data from its own analysis:
