We have been in the business of industrial waste recycling for 25 years, having developed mobile and stationary screeners and technologies to bring more value into the recycling process by recovering the most useful materials and giving operators the right equipment to landfill as little waste as possible. 25 years later over 600 Ecostar disc screens are successfully treating different materials in very distinct environments around the world, and our work is not done. With a population that is constantly growing – the United Nations projects that by the end of the year the global population will reach 8 billion people, almost 13% more than 10 years ago – the world will produce more waste.  Working towards a circular economy, the materials we recover must overcome the waste we produce, and Ecostar disc screens are best suited to do the job. Before discussing the Ecostar screening systems’ advantages in real cases, let’s briefly see what some of the recycling needs are today.

Waste and recyclable materials to be tackled globally

Entire regions and states are doing their best to reduce their waste and find solutions to recover and reuse waste and recyclable materials. The needs are different depending on the public policies and legislation, the number of waste management systems in place, objectives set by Governments or higher forums, or even public pressure.

In regions or countries where the separate collection is not mandatory or fully implemented there’s still too much MSW that hits landfills or open dumps, take for example some Asian countries, or some Western Balkans countries, where according to an European Environment Agency report in 2022, most municipal waste is sent to landfill. Moreover, a WorldBank report from 2016 states that out of 45 cities in Europe and Central Asia that reported some type of source separation, paper and cardboard, plastic and packaging and glass are the streams of waste most separated at source. While organic waste (food and green) is still not fully separated at source, thus much of it is lost.  Organic waste, by the way, seems to be the highest component of our entire waste globally.

Europe, on top of the recycling targets set by the European Commission, is now facing an energy crisis, thus organic waste became an extremely valuable resource to produce biogas and biomethane. A great example of managing food waste comes from Copenhagen, which starting this October will use the collected food waste to produce biogas and biomethane to replace fossil fuels.

Italy, for example, has 1.7 billion euros coming from PNRR (Piano Nazionale di Ripresa e Resilienza) to develop new biomethane production plants or modernize old ones aimed at producing clean fuel for transportation, residential homes, industry and the services market. But the Italian PNRR is also providing 2.1 billion euros to invest in improving the management of waste and boosting the circular economy in various sectors as:

  • Paper and cardboard
  • Textile
  • Plastics
  • And electrical and electronic equipment

Romania also has incoming funds of 1.2 billion euros from PNRR to improve and increase investment in waste infrastructure. Part of the resources is destined for the development of collection centers for bulky waste that are to be designed and implemented by the local authorities.

How can operators benefit from using the Ecostar disc screens in their plants?

Thanks to our Dynamic Disc Screening, Hyper Dynamic Disc Screening and Screening Width Adjustment technologies and our 25 years of experience in treating waste, operators can take great advantage of working different materials with our stationary or mobile screeners, depending on their operational needs. Here are some key examples of our screens at work:

1. Screening of organic waste in Croatia. This is the story of Ponikve eko otok Krk utility company in Croatia, which in 2020 decided to implement a complete sorting line – Ecostar’s Hexpert system – to treat organic waste from the island of Krk. The sorting line works at a capacity of 10 T/H, 500-600 kg /m³ bulk density, and 40-60% humidity, and separates the organic material from torn bags from other unwanted waste. The under-screen fraction is treated by a magnetic belt separator to remove any metals with an excellent degree of cleanliness. The organic material is sent to the aerobic digestion process. Besides the quality of separation, the sorting line has another great advantage, thus an energy consumption lower than 44 kWh for a total installed power of 56 kW. To find out more about the system.

2. The separation of organic waste from MSW is extremely necessary where the organic waste is not separated at the source. This is the case of an Hextra mobile disc screen with DDS technology in a plant in Italy, where the waste gets separated into two fractions of 0-20mm organic section, and oversize. The Hextra 2F is equipped with a DDS anti-wrapping system, can be equipped with a diesel generator or 100% electric supply (depending on the operator’s needs), a screening variation system, and a sliding feeding system.

3. Waste to energy is another area where Ecostar screens are leading the way. Here we are in a plant in the UK, where our stationary dynamic disc screen Hexact is treating waste for SRF (Solid Recovered Fuel) at a capacity of 30 T/H and a required screening section of 0-20mm. The Hexact screen works in a line with a pre-shredder and in the first two months of operation the stationary screen worked more than 800 hours, requiring zero cleaning maintenance.

4. Plastic recycling. To get different raw materials from plastics a multi-fractions screen is necessary. Thanks to our screeners and technologies the operator can screen up to 20 T/H of plastics at different fractions of 20, 50, 100, 150 and 200mm. Should the operator need to pass from a 20omm to 150 mm section or from 200 mm to 100 mm, SWAT is our technology with which one can quickly change the screening section on-site, which is to be installed on DDS screens.

Come and meet us at Ecomondo, at stand 050, in the A3 pavilion

At the Ecostar booth, you will be able to check out our machines in action with various materials in different environments within our client’s recycling plants. We are to display our stationary screen Hexact 5000, a modular solution equipped with the DDS technology designed to treat materials such as compost, wood, biomass, metals, tires, glass, car fluff, RDF/SRF, or construction and demolition debris. The DDS technology is known for providing high performance in terms of productivity, quality of separation, and -70 power consumption thanks to the 7.5 kW electric motors. Moreover, the Hardox discs lead to lower maintenance costs due to wear while the anti-wrapping and anti-clogging system to lower maintenance and downtime of the machine.
