Since 2000, Aldesa has held ISO 14001:2004 certification for Environmental Management from AENOR; this ensures compliance with applicable environmental legislation and regulations relating to the environment and the use of processes which avoid, reduce or control pollution, placing particular emphasis on prevention and ensuring continuous improvement in the company's environmental performance.

In order to meet the requirements of this standard, Aldesa draws up an Environmental Management Plan for each job which, in addition to identifying and evaluating the environmental issues generated by activities on the job (waste, atmospheric emissions, noise, etc), identifies the applicable environmental legislation and ensures full compliance with all such legislation and regulations by the Company itself and its subcontractors, and establishes an objective for environmental improvement.

In addition, the Group establishes direct environmental improvement actions for each of its projects, by setting environmental objectives. The main impact of construction work is the quantity of inert waste generated (those materials which are not physically, chemically or biologically transformed in any way), such as the material from excavations or demolition, rubble, wood and scrap metal. As part of its environmental commitment, the Company is working to reduce continuously the amount of such waste that is sent to landfill sites.

The Company seeks alternatives, such as recycling on the job itself by looking at other options to the original plans; or, in the case of excavations, sending the material excavated to other projects which require earth, thus avoiding the need for new quarries. Another alternative to depositing waste in a landfill site is to use excess material for agricultural improvements. Waste wood and metal is handed over to authorised bodies for recycling.

Dangerous waste materials – those which due to their composition and properties are potentially dangerous for health and the Environment, such as empty spray, paint, resin, foam and silicate containers, and waste from machines, such as brake oil, filters, used oil, etc – are separated and managed for each job by companies authorised by the competent authorities.

Noise pollution and atmospheric emissions are controlled through control of the machinery used on the site, by preventative maintenance and by use of recently manufactured machinery and ensuring that all official technical inspections are up-to-date.

As part of its Recycling Policy, the Group’s offices ensure systematic collection of waste material such as paper and toner from printers and photocopiers on a daily basis using authorised companies, which then recycle and reuse, respectively, the waste.

To practically implement these policies, Aldesa has drawn up various good practice manuals which are given to the relevant workers. The Company also shares its environmental concerns with its suppliers and other companies it works with, particularly when their activities could have a significant impact on the job, ensuring that their employees have the appropriate training and environmental awareness to carry out their tasks.
