Innovation in growth, sustainability at the core Our commitment to eco-friendly solutions and innovative technologies places us at the forefront of sustainable development. At Certhon, sustainability is at the core of everything we do. With our deep knowledge and experience, we help growers achieve their sustainability goals while simultaneously increasing their productivity and profitability. Our advanced greenhouses utilize technologies such as geothermal energy and biomass to ensure a minimal ecological footprint. Energy & CO2 By using renewable energy sources, CHP systems, ATES, solar and geothermal energy, we reduce reliance on fossil fuels. Water & Chemistry Our recirculation systems and water-saving technologies drastically reduce water consumption and minimize waste of resources. Circularity & Society Our data-driven approach enables growers to make decisions based on real-time insights, leading to more efficient cultivation processes and less waste. Our approach to sustainability Sustainability is woven into everything we do. We strive to minimize our ecological footprint by developing efficient and environmentally friendly solutions. This commitment extends to both our operations and the projects we undertake. All our projects aim to increase energy efficiency and reduce water consumption without compromising crop quality. Innovation as the driving force Innovation is central to our sustainability strategy. By continuously investing in research and development, we introduce groundbreaking technologies that reduce the environmental impact of horticulture. Our advanced greenhouses and indoor farms employ the latest techniques in climate control, LED lighting, and automated cultivation systems. These innovations enable growers to achieve higher yields while using fewer natural resources. Sustainable energy solutions At Certhon, we prioritize sustainable energy sources such as geothermal energy, waste heat, heat pumps, green gas, electric boilers, CHP systems, and biomass. These innovations reduce reliance on fossil fuels and minimize the ecological footprint of our projects. Our technologies provide efficient energy solutions that contribute to a green and sustainable future for the horticulture sector. Sustainable solutions in practice All our solutions are designed with a future-forward approach and are successfully implemented today. We integrate smart technology and plant sciences with a commitment to achieving the most sustainable and energy-efficient solutions. Each innovation promotes sustainability and moves us closer to emission-free cultivation. Here are just a few of the innovations and techniques we deploy in our project implementations: Smart air circulation The JSK represents a world-first in precision cooling technology. Developed by Certhon, this unique cooling system is designed for both cooling and dehumidifying greenhouses. Its intelligent air circulation ensures highly uniform air distribution. Combined with precise control over relative humidity and temperature, this system maintains optimal climate control within the greenhouse. By utilizing waste heat, our greenhouses operate as highly efficient energy sources, resulting in significantly reduced energy costs. Heat pump In addition to heating the greenhouse during winter by extracting heat from the ground, the heat pump also serves a crucial role in summer. It can be used to cool the greenhouses using cold water, utilizing only natural heat sources and maintaining a consistent temperature inside the greenhouses. Thermal Energy Storage System (ATES) Excess heated water produced during summer is stored in the ground using a thermal energy storage (ATES) system. A heat pump extracts heat from the ground when heating the greenhouse is required again. Aquifer Storage & Recovery (ASR) Captured rainwater is temporarily stored above ground for filtration purposes. Using a specialized well, the filtered water is then infiltrated into an aquifer layer in the ground. When water is needed for cultivation, it is pumped up as required and stored in the above-ground rainwater storage. Underground water storage proves to be a smart and functional solution for preserving water for future use. Aquathermy system An aquathermy system efficiently and sustainably heats greenhouses by harnessing natural heat from surface water sources, such as canals. Implementing an aquathermy system enhances the sustainability of greenhouse heating solutions even further. Maximizing energy-efficient cultivation Real-time insights into plant transpiration and photosynthesis provide growers with the knowledge needed to cultivate as energy-efficiently as possible and improve production. This includes optimizing water delivery, preventing diseases and pests, and initially focusing on the relationship between photosynthesis and transpiration. Cultivation trials in climate chambers thus become an indispensable tool for optimal resource utilization in greenhouse farming. Sustainable Development Goals Goals By questioning the status quo of growing we can constantly improve how we feed and green the world. We believe in a healthy world for everyone. In terms of food, ecology and the economy. So we continually challenge ourselves and our customers, not only to reinvent food systems, but also to help shape a healthy economic climate that matches those beliefs. 06.
