Among the activities of Efacec Ambiente, solid waste treatment and processing is the most recent, meeting the goals set for the global improvement of environmental issues.

Efacec Ambiente's intervention scope ranges from mechanical sorting systems to advanced solutions incorporated in municipal and biodegradable solid waste treatment and processing plants.

Solid waste treatment and processing plants are highly suitable, efficient and competitive technological solutions for waste treatment, namely allowing the:

• Production of organic compost through composting processes, which may later be used as a fertilizer in agriculture;
• Production of biogas through anaerobic digestion of the organic fraction, which may be used for electrical and thermal energy production;
• Separation of recyclable items through selective sorting technologies;
• Reduction of organic matter disposal in landfills.

Efacec waste treatment plants also integrate state-of-the-art technology for odour control and wastewater treatment, allowing its reuse within the process or direct discharge into the surrounding environment.
