Waste sorting analysis
Advice to municipalities on waste management (environmental performance, service and costs) based on sorting analyses and quality controls of the waste plus an inventory of the opinions of residents.
Flares and gas treatment
Hofstetter is the world’s leading specialist in flaring technology and degassing systems. The company was established in 1975 and to date has installed more than 1,700 systems around the world. Hofstetter solutions and products within the field of gas technology and gas combustion are used everywhere where combustible gases have to be collected, transported or disposed of. We are your partner for landfill gas, biogas, mine gas and industrial gas.
Blue algae control, water chemistry mapping and offshore innovation
TerraCrawler offers an innovative and sustainable solution for water quality management. We use a natural mineral, lanthanum, which binds free phosphates in the water through smart, autonomous distribution. These phosphates are the nutrients for blue algae. With this approach we prevent the growth of blue algae.
Modular digestion of biodegradable waste
The company BioBlox BV offers large scale (custom made) and small scale (modular and scalable) solutions for the treatment of biodegradable waste into energy and organic fertilizers. A key innovation is the application of horizontal digestion tanks, allowing for a better digestion compared to the vertical silo process. The small BioBlocks-based plug and play installations can be deployed within a few months and can be an ideal solution for the organic waste output of e.g. food companies, resorts, farms and waste management centers.
Ammonia Removal: Amotek Hybrid Bio-Chemical Reactor
The Amotek system is a pioneering hybrid bio-chemical reactor designed specifically for ammonia removal, the first of its kind that does not require chemical dosing. This technology is versatile, catering to various sectors including agriculture, paper mills, composting facilities, and other industrial applications. Key Features: - Co-current Trickling System: Engineered to effectively remove ammonia with over 99.5% efficiency. - Broad Application: Suitable for agricultural settings and also effective for reducing ammonia emissions in paper mills, composting facilities, and various other industries. - Future Prospects: Expected to become a leading technology for ammonia reduction, akin to the success of the TORRENTA system for H2S reduction. Why Choose Amotek? - Hybrid Bio-Chemical Reactor: Specifically designed for ammonia removal. - Reliability: Offers consistent performance with few moving parts, extremely high reliability, and near-zero maintenance requirements. - Cost Savings: Features simple installation and minimal disruption to ongoing operations. - Efficiency: Achieves over 99.5% ammonia reduction efficiency. The AMOTEK Process (Patented Technology): - Air polluted with ammonia and organic compounds is introduced into the system, where it is absorbed into a liquid and converted into ammonium (NH4). - The ammonium then travels through the AMOTEK system, oxidizing to form nitrite (NO2). - Finally, the nitrite is converted into nitrate (NO3), and the air exits the system as clean, purified air.
DOPS Recycling Technologies bv: Syngas out of waste
The so-called Direct Carbon Immobilization (DCI™) technology is a thermo-chemical process that produces syngas and fixed carbon, minerals, and metals out of all kinds of hydrocarbons containing waste. The process is currently being tested on a laboratory scale. In 2025, the installation will be scaled up in a modular way to serve a variety of waste streams, including biomass, paper waste, and all sorts of plastics. A great benefit is that, contrary to Waste Incineration Facilities, the process produces no direct emissions of CO2 and keeps carbon and many minerals and (precious) metals available for retrieval.
The Waste Transformers
Our containerized, modular biodigesters turn your food waste into clean energy and biobased fertilizer, right at your premises. By transforming food waste into value, you comply with regulations, strengthen your brand image, attract eco-conscious talent, and showcase your real commitment to sustainability, innovation and real CO2 reductions.
