The Madrid City Council has launched a specific plan to transform El Retiro Park into the Europe's first historic park with 'Zero Waste' certificationThe strategy focuses on completely transforming the way waste is managed within this iconic green space in the capital.
The project aims to have, by 2027 at the latest, at least 90% of the waste generated in the park is reused, recycled or transformed before reaching the landfill. With this, El Retiro aims to become a European benchmark in urban sustainability, aligned with the circular economy policies of the European Union.
A green lung, a World Heritage Site, with a serious waste problem
El Retiro is one of the Madrid's most important green spaces It forms part of the Landscape of Light, declared a World Heritage Site by UNESCO. Its 118 hectares of gardens, ponds, and walkways receive more than 20 million visitors each year, both locals and tourists.
This massive influx has a less visible side: the park generates more than 2.700 tons of waste per yearUntil now, most of that waste ends up mixed together and sent directly to landfill, because the The current waste bin system does not allow for the proper separation of different types of materials. at the moment they are thrown.
The figures handled by the City Council are clear: around 95,4% of the waste corresponds to the residual fractionThat is, unsorted waste that ends up without being reused. Glass accounts for approximately 4,1% (around 108 tons annually) and the organic matter barely reaches 0,23%, about 6 tons.
Something similar happens with packaging and paper or cardboard, which barely reach 2,5 tons each. On the positive side, the tree pruning and maintenance waste, about 205 tons per yearThey already have a specific recycling circuit outside the conventional waste bin system.
Renewal of nearly a thousand waste bins to separate waste at the source
One of the central pillars of the municipal plan is the complete renovation of the 984 waste bins distributed throughout the parkCurrent systems do not allow for the separation of glass, packaging, paper, cardboard, or organic waste, forcing everything to be mixed together and complicating any subsequent recycling attempts. The project proposes, among other measures, to facilitate separate glass, packaging, paper, cardboard or organic from the street furniture itself.
The new container model will focus on the selective separation of waste at sourceso that visitors and employees can dispose of each type of waste in the correct bin from the outset. The aim is to meet the standards required for 'Zero Waste' certification and to make it easier for visitors and employees to dispose of waste properly. the materials give a second life.
With this renovation, the City Council hopes that it will no longer be “normal” for almost all of El Retiro Park's waste to end up directly in the landfill. The idea is that, with a clearer and more visible collection system, the everyday behavior of those who stroll through the park Also, change and get used to properly separating your waste.
This action not only has an environmental dimension, but also one related to the use of public space: the aim is that the visitor experience improvesreducing the dirt and the feeling of disorder associated with overflowing bins or bins with mixed waste.
A new 3.000 m² recycling center in the southern area
Alongside the renovation of street furniture, the City Council has begun work on a waste management center within the park itselfThis facility is located in the southern area, next to the Rose Garden and the Greenhouse Nursery, in a space that until now was only used as an unconditioned collection point.
The future center will occupy around Sqm 3.000 and will have five separate disposal areas, designed to facilitate more efficient selective collection. The planned investment is around 474.000 euros municipal budget, as detailed by the City Council.
Among the planned actions, the following stand out: reduction of asphalt surface and the adaptation of the land so that the area blends better with the park's surroundings. In addition, a new interior lighting network will be installed to improve safety and working conditions, and the perimeter fence will be maintained to preserve access restricted to authorized personnel.
This center will not only allow for the organized temporary storage of garbage, but also optimize the classification and valorization of the different waste streamsThe idea is for the park to have its own management system, closer to and adapted to its specific needs, instead of depending exclusively on external infrastructure.
Objective: to recover 90% of waste and achieve the 'Zero Waste' certification
The municipal plan has a well-defined goal: that El Retiro meets the requirements of the 'Zero Waste' certification, a distinction that recognizes organizations and spaces that manage to minimize the amount of waste that ends up unused in landfills or incinerators.
In practice, this means that at least the 90% of the waste generated in the park must be reused, recycled, or subjected to valorization processesOnly a small residual fraction could ultimately be disposed of, provided it is shown that there is no reasonable margin for giving it another use.
To verify that these levels of material recovery are achieved, an independent entity, Bureau VeritasThe company will be responsible for auditing waste flows in El Retiro Park. The monitoring process will last approximately six months, analyzing how each type of waste is managed from the moment it is deposited in the bins until its final destination.
If the audits confirm that the required criteria are met, the municipal forecast is that Official certification may be granted by mid-2027In this way, El Retiro would become the first European historical park to externally accredit a waste management model based on the circular economy.
A project aligned with European circular economy objectives
The transformation of El Retiro is not understood solely as a local initiative, but as a way of adapt Madrid to the goals set by the European Union Regarding waste, EU legislation sets a target of reducing the amount of waste sent to landfills by up to 10% by 2035, promoting reuse, recycling, and other forms of recovery.
Turning this park into a Zero Waste example fits with that European roadmap and reinforces the city's image as a leader in urban sustainability and heritage protectionThe project combines the preservation of a historic garden with the incorporation of advanced environmental criteria.
The City Council also emphasizes that these types of projects serve to to raise public awareness about responsible waste managementAs it is such a well-known and frequently visited space, any change in El Retiro has a strong symbolic effect and can contribute to normalizing waste separation practices in everyday life.
In the long term, the El Retiro experience could work as This model can be replicated in other parks and green spaces in Madrid and Europe.If the segregated waste bin system, the new recycling center, and external monitoring work as expected, it wouldn't be surprising if other cities consider similar initiatives.
With the investment already committed, the works underway, and a timeline looking ahead to 2027, El Retiro is preparing to go from being just a historical and cultural icon to also becoming a living laboratory for sustainable waste managementThe combination of new infrastructure, changes in street furniture, and independent audits will determine whether this Madrid park finally manages to position itself at the forefront of Europe in the fight against waste.
