Diversity and efficiency through environmental work

Efficient infrastructure serves the needs of residents and companies and is environmentally effective. Environmental impacts are inevitably created from construction and maintenance during the life cycle. Destia’s aim is to minimise the impact on the environment for the good of biodiversity and people. At the same time, we are constantly working to improve resource-, material- and energy-efficiency.

Environmental management is based on a management system (ISO 14 001) used throughout Destia. This system ensures that environmental issues are taken into account in all operations and that management is goal-oriented. Infrastructure projects also entail much licensed activity and regulation. Destia operates in accordance with environmental legislation and regulations.

As part of project management, Destia is monitoring the level of satisfaction of customers towards its care of environmental issues.

The use of soil and aggregates

Every year Destia uses about 3 million tonnes of soil and aggregates. Destia has 316 licensed aggregate areas. In 2015, active work went on at about 100 areas.

From an environmental perspective, one of the key fields of responsibility in the extraction of soil and aggregates is to work for the good of biodiversity. The most important work is done in the planning stage of aggregate areas. When acquiring new areas, their natural values are investigated in advance. Protected areas and those otherwise valuable from a perspective of nature are left outside the area of operation. Legislation specifies the most valuable species and habitats, but on its own initiative Destia also aims to conserve other valuable locations.

Extraction areas at the end of their life cycle are treated so that vegetation returns to them as quickly as possible. Biodiversity can also be increased through extraction. For example, a quarry pond, a cliff for birds to nest on or a sunny slope for sun-loving vegetation may be created in the area.

Improving work efficiency

Destia is a pioneer in the use of construction machine automation. Construction machine automation is in use at almost all suitable Destia civil engineering-focused sites. The aim is to boost the performance and precision of work and to reduce material waste. Destia substitutes the use of non-renewable natural resources with renewable alternatives whenever possible. Examples include the reuse of crushed concrete and crushed material made from waste asphalt. In road projects, we use old structural layers where possible.

In project activity, we pay close attention to the planning of operating practices and logistics. We aim, among other things, at the optimisation of fuel consumption and material efficiency. The use of Destia’s fleet of trucks is monitored using a GPS-based system. By combining operating and fuel cost information, we get precise information about the efficiency and economy of each truck. The efficiency of the usage of fleet is monitored in railway business as well.
