One of the key values of Aleia Roses is the sustainable production of roses while respecting the environment in each phase of the process.


Sustainable cultivation allows us to control pests and diseases without endangering the health of people and without leaving an impact on the environment.

‘We produce high-quality roses with respect for the people and the planet´,
explains Pablo Villalaín (Integrated Pest Management Manager at Aleia Roses). 

The facilities of Aleia Roses are designed to cultivate in an ecological way, without a pollutive and irreversible impact on the environment.


Thanks to a state-of-the-art computer-driven system, each operation can be controlled precisely, the highest quality can be obtained, and it allows us to make use of all resources in a sustainable way.


One of the pillars of sustainable production is to prevent attacks of plagues and diseases in a biological way. To avoid them, Aleia Roses cooperates with Koppert Biological Systems to implement an Integrated Pest Management program.


In this method biological solutions are being used over chemical ones, fighting the pests with their natural enemies. We prioritize the use of biological solutions following all the certifications that aim to reduce the risks of exposure to chemical products and ensure environmental protection and well-being of the employees.


We collect rainwater in two rafts of 24,000 m3 each, collecting also from the entire roof of the greenhouse. In addition, the water from the irrigation system is purified and reused again. A computerized system of irrigation with added fertilizers waters the crop according to the needs, influenced by the climatic conditions.


Thanks to this system and the excellent water of the nearby river Duero too, the water consumption is reduced in 50% from usual consumption in hydroponic cultivation.


Thanks to the hydroponic cultivation, Aleia Roses increases the productivity compared to traditional growing methods and avoids the contamination of aquifers and soil. This results also in achieving a very efficient way of using water and fertilizers.


Energy saving screens to avoid the loss of warmth.


Use of light structures with diffuse antireflection glass cover, which “diffuses” the intensity of the sun’s rays and distributes them evenly.


Carbon enrichment favours photosynthesis, as well as the productivity and the quality of our roses. CO2 is obtained by burning natural gas for heating, according to the heat demand. In this way, the emission of CO2 into the atmosphere is avoided and the impact on global warming is reduced.


In the near future, the greenhouse will get warmth from the neighboring biomass plant. The emitted gases will be filtered to extract and use in the greenhouse the produced CO2.



According to the United Nations and the European Union, innovation in agriculture and horticulture is the number one priority. The objective of innovation must be to safeguard and, if possible, increase the production of healthy food per hectare, with minimal use of artificial fertilizers and chemical pesticides. Most scientists agree on the fact that this is only possible if cultivation is done according to the concept of Integrated Pest Management.


Sustainable farming consists of all possible crop protection techniques, including monitoring, crop sanitation, mechanical or cultural control, and the introduction of beneficial insects and mites. The use of corrective chemical control measures is to be the last resort.
