Ros Roca S.A. was founded in 1953 and has concentrated its activities in the environmental sector with specialization in waste collection and waste processing systems.
Within the Ros Roca group further European enterprises owned or partially owned by Ros Roca are working in different countries with Ros Roca's products and services. Besides the main company business of waste collection systems like refuse collectors, street cleaning machines, vacuum systems, and pneumatic waste collection systems, waste processing systems obtain increasing importance.
This is the consequence of a worldwide growing demand for waste treatment in order to protect the environment. Ros Roca is one of the market leaders in the world in the environmental sector with 1.100 employees and exporting environmental technologies to more than 70 countries.

In the Ros Roca Group the two companies Ros Roca S.A. and Ros Roca Internacional S.L. have started their activities in the early 1990s with waste treatment technologies. Meanwhile different innovative, efficient, environmentally-friendly and economically interesting waste treatment solutions are offered to customers all over the world.
Numerous industrial scale plants with capacities of up to 100.000 tons per year are in operation in different European countries and the key personal has an experience of more than 10 years in implementing such plants.

The main focus of our activities are mechanical-biological waste treatment systems combining sorting, digestion and composting systems where energy producing systems gain more and more importance following the general strategies for waste treatment in Europe. Having a strong financial power the companies are mainly working as 
| Anaerobic Digestion Advantages of this digestion process
Process works independently from humidity of waste
High flexibility in treatment of different types of organic waste
High biogas quality
Little exploitation costs
Hygienization according to EU Animal By-Products Regulation 1774/2002
High compost quality
High flexibility in marketing of digestate or compost
No moving elements in the digestor
Little energy consumption
Little wear | 
| Composting in rotating drums Organic waste can also be treated efficiently by aerobic composting in rotating drums.
Here the first intensive composting process takes place in a closed, forced aerated and temperature controlled steel drum with an especially developed protection layer against corrosion inside.
The process is a dynamic system with the possibility to move the drum in a controlled way with a speed of up to 1 rotation per minute.

| Composting in tunnels The composting of organic waste is a proven and well developed technology. The tunnels are fabricated in concrete in different sizes and are equipped with an aeration floor developed by Ros Roca.
The organic material is charged into the tunnels by front-end loader or automatically with conveyors. For aeration each tunnel is equipped with a blower which is blowing air through the aeration floor to ensure an efficient oxygen supply of the microorganisms.
For charging or discharging the tunnels they are equipped with doors which are gas-tight to assure that no odour-loaded air can leak during the composting process. Usually the organic material is composted for two weeks in the tunnels. After that the organic material will be finally maturated by windrow composting. The process parameters like temperature, oxygen, carbon dioxide are measured continuously and are used to control the composting process. Odour-loaded air from the composting process is sucked off by ventilators and cleaned by scrubber / biofilter.
Advantages of the tunnel composting process
Composting in closed units makes possible specific sucking of odour-loaded air
Minimised air consumption by computer control
No mechanical equipment in a corrosive atmosphere
Economic solution for small and big capacities
Modular system easily extendable
Simple compost maturation in windrows
