Technical confinement in landfill

BLUEOTTER possess two landfill technical confinement units, in Setubal and Alenquer, with an annual capacity for the treatment of non-hazardous waste of 130.000 metric tons/year.

Both units, considered state-of-the-art, integrate the environmental, safety and health dimensions in every action concerning their management, complying with every available legislation and best practices available.

Valorisation and Production of Alternative Fuels

BLUEOTTER has two RDF (Refuse Derived Fuel) production lines, one in Setubal and another in Alenquer. These lines can process up to 100,000 metric tons per year.

RDF valorisation allows to reduce the volume of landfill technical confinement, deviating a significant fraction of waste which for its characteristics, namely calorific power, may be subject to a different valorisation operation.

The RDF line of production basically consists on a pre-shredder, having a rigorous control, a magnetic splitter for the removal of iron materials, an air splitter to sort the lightest fraction and to which a higher calorific power is associated and, finally, an ultimate shredder (adjuster), which will assure that the RDF dimensions comply with the requests of energetic valorisation units (cement kilns, boilers, among others), followed by another iron splitter. There is also a metal splitter on the refuse end (heavy fraction)

The final results in respect of the quality of the RDF produced are in line with the highest quality standards pursuant to the Portuguese Standard.

Sorting and Recycling

In Setubal BLUEOTTER has the capacity to store and sort construction and demolition waste (CDW), as well as non-hazardous waste totalling 150,000 metric tons per year.

Organic Valorisation in Bioremediation

BLUEOTTER has the capacity to treat and recycle organic waste by means of bioremediation totalling 28,000 metric tons per year in Setubal.

Resorting to Bioremediation organic valorisation is an ecologic method for the environmental recovery of soils, presenting a higher cost-benefit ratio by comparison to traditional methods of physical and chemical removal of pollutants.

Our facilities in Setubal were the first ones to develop this innovative project nationwide, resorting to this recycling biological process for waste that normally would be destined to deposit in landfill.

The list of EWL codes covered by the operator`s waste management license No. 063/2016, CITRI, regarding Bioremediation is presented below:

Composting Organic Valorisation

BLUEOTTER is developing a modern and innovative treatment and valorisation composting unit for organic waste, in Setubal, with the capacity to treat 60,000 metric tons per year.

This unit will allow to obtain a quality organic compound to be applicable in agriculture. The compound will be subject to a strict alignment with the current Law on Fertilizers.

The beginning of operation of this unit is expected for 2019.

Renewable Energies Production

BLUEOTTER produces Renewable Energies using two energy production plants.

In Alenquer, the solar plant is made of 450 photovoltaic modules and is used for self‑consumption with the purpose of diminishing the energetic dependence of our facilities.

The biogas electric energy production plant in Setubal has a power of 1 MW.

Research, Development and Innovation

BLUEOTTER intends to actively contribute towards the improvement of the quality of the management and environmental management of the sector. In that sense, the company undertakes internal projects for innovation and automatization of procedures while developing partnerships with multinational companies allowing access to the most advanced technologies and methodologies for environmental preservation.

Logistics

BLUEOTTER possesses logistic means for waste transportation and storage, directed mainly towards solid and organic waste.

Laboratory

To offer added value services to clients, the Setubal and Alenquer units possess laboratory departments with highly qualified equipment and professionals holding high technical and academic capacity, with credentials and certified pursuant to Standard 17025.

Read more

The laboratories main function is environmental monitorization, including the characterization of waste destined to landfill, effluent muds, residual waters and RDF (Refuse Derived Fuel) for both units and provide services to a wide range of external clients.
