It is common not to know well what to pour into the gray container, especially in cities where the brown container also exists. In Spain, the recycling containers The most well-known are yellow (plastic and metal containers), blue (paper and cardboard) and green (glass). But what is recycled in the grey container? In this article we will clear up any doubts about its use and provide you with clear and detailed information.
Errors with the gray container
The grey container is the oldest type of waste collection system, and has traditionally been used for waste that no one knows where to deposit. However, throwing any type of waste into this container is a common mistake. Although not everything can be recycled, it is important to correctly classify what should specifically go into the grey container.
For example, waste such as batteries, used oil or electronics have their deposits or specific collection points, and must be taken to clean points for proper treatment and recycling. The most common mistake is not properly separating these special wastes that do not belong in the grey container, thus worsening the efficiency of recycling systems.
What to put in the grey container?
The grey container is intended for waste that is not recyclable and cannot be composted. This includes a large amount of biodegradable waste that eventually decompose on their own, but cannot be used to make new products or compost.
Some examples of what we can pour into this container are:
- Food waste and pruning that cannot be composted or are too complex to handle, such as bones or fish bones.
- Hygienic products such as diapers, pads, wipes, cigarette butts or cork stoppers.
- Household cleaning waste such as dust or hair that we collect when sweeping or vacuuming.
- Small objects such as chewing gum, baby bottles, pacifiers or any similar type of waste.
It is important to note that although not everything that goes into the grey container can be recycled in the traditional sense, it can be managed appropriately to avoid additional contamination. Much of this waste will be taken to controlled landfills or incinerators. These processes allow for the creation of clean energy or proper waste management to reduce its environmental impact.
Is waste from the grey container recycled?
It is a common question: is the waste in the grey container recycled? Although the answer is not a resounding "yes", many of these wastes can receive a proper treatmentFor example, some non-recyclable plastics or textiles can be reused to produce energy, through controlled incineration processes that limit pollutants.
A clear example is the obtaining of compost from biodegradable waste. However, the presence of impurities such as cigarette butts or sanitary items in this waste means that it is not possible to obtain good quality compost, which justifies the separation between the brown container (for pure organic matter) and the grey container.
In fact, waste that cannot be used ends up in controlled landfills, where it undergoes exhaustive compaction and classification processes. Its decomposition is also monitored to prevent contamination of soil and groundwater.
Differences with the brown container
El brown container It is specifically designed for waste reusable organicThis includes fruit and vegetable scraps, peelings, pruning waste, or even coffee grounds and eggshells. The main difference with the grey bin is that the waste from the brown bin undergoes a composting process to make natural fertiliser, while the grey bin collects what cannot be used in this way.
Separating this waste correctly is essential to avoid contaminating the compost. For example, cigarette butts or sanitary pads cannot decompose naturally like fruit peels. Proper use of the brown bin allows you to make the most of organic waste and minimise the use of chemical fertilisers, which helps to preserve the environment.
What you should not throw in the grey container
In addition to waste that should go into other recycling containers, such as plastics and packaging in the yellow container, glass in the green or paper and cardboard in the blue, there are also a series of products that should never be thrown away to the grey container:
- Hazardous waste such as oil, batteries, paints or chemicals, which require special treatment in clean points.
- Household appliances and electronic devices, which must be placed in specific containers or taken to recycling centres.
- Glass containers, which must go in the green container.
Separate waste properly allows us to reduce the amount of waste which reaches landfills and enables recyclable and reusable materials to be used to their full potential.
If you want to do your part to help the environment, it's vital to make sure you're managing your waste correctly at home. The brown, yellow, blue and green bins all have a clear purpose, as does the grey bin, which should be reserved for what can't be recycled in other ways. As recycling policies continue to improve, we're likely to see a noticeable reduction in the use of grey bins, in favour of more sustainable systems based on composting and reuse.
