Overview

In 2006, Evergreen Waste Systems, a division of the Evergreen Group, introduced the Thermo-Compactor-Desiccator® (TCD). This system, though no longer in production, was a pioneering technology in sustainable waste management, addressing the challenges of Urban Solid Waste (USW) with an environmentally friendly and cost-effective approach.

Key Features of TCD Technology

The TCD system was designed with a focus on environmental sustainability, aiming to reduce gas and liquid emissions, produce refuse-derived fuel from waste, and ensure compliance with legal regulations and standards. The process combined pressure and heat to desiccate and compact waste, operating at temperatures between 100°-200°C without incineration. This resulted in a sterile, odor-free, and compact end product.

The system effectively captured and treated vapors using bio-filters, significantly reducing carbon dioxide and other harmful emissions, and achieving near-zero emissions during the treatment process. By extracting water content, the TCD reduced waste weight by up to 30% and compacted waste to high densities, effectively doubling landfill capacity.

Cost efficiency was a major advantage of the TCD system, with low operational costs due to reduced emission treatments. The system was also eligible for government subsidies for low environmental impact technologies, and simplified logistics reduced transportation costs and requirements. The TCD featured a continuous, automated process managed by programmable logic controllers (PLC), and its modular design allowed for scalability to handle varying waste volumes. Real-time remote monitoring ensured reliability and facilitated maintenance planning.

In terms of hygiene and safety, the TCD sterilized waste, eliminating health hazards associated with traditional landfills, and prevented groundwater contamination, reducing the risk of diseases.

Engineering and Reliability

The TCD plant was engineered for durability and ease of maintenance, with a lifespan exceeding 20 years. Components were certified to European Union standards, incorporating corrosion control and high-quality materials to ensure long-term reliability.

Applications and Implementation

Ideal for installation at waste transfer stations, landfills, or incinerators, the TCD system enhanced the efficiency of waste management systems by reducing the need for daily transportation and special handling of waste.

Conclusion

The Thermo-Compactor-Desiccator® (TCD) technology from Evergreen Waste Systems, introduced in 2006, marked a significant advancement in sustainable waste management. Although no longer in production, the TCD system provided notable environmental, economic, and operational benefits, aligning with Evergreen’s mission to improve global environmental standards at lower costs and higher efficiency.

Evergreen Walls

Overview

In 2016, Evergreen Systems showcased their innovative Evergreen Walls® technology, a sustainable construction solution using precast concrete elements. This technology, developed to address environmental concerns, was first introduced in 1976 and has since been implemented in over 1,500 projects worldwide.

History and Development

Evergreen Walls® was conceived by Felix P. Jaecklin, with the first wall constructed in Zurich in 1976. Over the years, the concept evolved to meet higher standards of aesthetics, structural performance, and environmental sustainability. The business expanded from Switzerland to various countries, including Germany, France, Italy, Spain, the USA, Canada, Japan, and several others, adapting to local construction codes and requirements.

Technological Features

Evergreen Walls® consist of precast concrete elements that provide durable and cost-effective solutions for a variety of construction needs. These walls are designed to minimize environmental impact, reduce noise, and improve structural integrity. The technology includes several wall systems, such as EVERGREEN® MACRO, MACRO Closed-Face, MACRO Back Beam, EVERWALL, GEO, MAXI, and EPF, each tailored for specific applications.

Competitive Advantages

The walls offer numerous advantages, including minimal land acquisition costs due to their near-vertical structure, reduced excavation needs, and immediate erection without on-site curing time. The use of large precast elements speeds up construction and reduces costs. The high-quality, durable construction ensures great stability and performance under heavy loads and adverse weather conditions. Additionally, Evergreen Walls® are designed to absorb CO2 and are graffiti-proof, making them environmentally friendly and low-maintenance.

Applications

Evergreen Walls® are versatile and can be used for various purposes, including slope retention, erosion control, noise abatement, security barriers, and blast impact resistance. They are suitable for highways, railways, parks, residential and commercial areas, mudslide-prone regions, waterfronts, embassies, and defense installations.

Acoustic Benefits

Evergreen Walls® are highly effective in noise reduction for highways, railways, and industrial plants. Their design ensures high acoustic absorption, reducing the transmission and reflection of sound. This makes them ideal for noise mitigation projects, including sound-absorbing tunnels and barriers.

Engineering and Reliability

The walls are engineered for durability, with a lifespan exceeding 20 years. The components are certified to European standards, ensuring high reliability and safety. The modular design allows for easy installation and maintenance, and the use of quality materials guarantees long-term performance.

Conclusion

The 2016 brochure highlights the continued innovation and global impact of Evergreen Walls®. These walls exemplify Evergreen Systems’ commitment to sustainable construction, offering significant environmental, economic, and operational benefits. Although no longer in production, Evergreen Walls® set a high standard for green wall technologies worldwide.

Evergreen Ozone

Overview

In 2006, Evergreen Ozone, a division of the Evergreen Group, introduced advanced systems for the treatment of air, water, and food products. These systems, based on cutting-edge ozone technology, were designed to improve microbiological safety, environmental sustainability, and operational efficiency. While the specific technologies discussed are no longer in production, they marked significant advancements in environmental management.

Key Features of Evergreen Ozone Technology

Evergreen Ozone developed machinery and plants that leveraged ozone’s powerful oxidizing properties to treat air and water, enhancing the management of microbiological risks. The company focused on creating solutions that complied with stringent hygiene and certification standards, including EMAS, ISO 14000, and Italian Law 155/97.

Environmental Sustainability: The technology utilized ozone, a natural gas that leaves no chemical residue and has a high oxidizing power, making it ideal for various applications. This approach ensured minimal environmental impact while maximizing safety and effectiveness.

Air Treatment: Ozone was used to improve indoor air quality by eliminating bacteria, fungi, molds, and viruses. The systems were applicable in homes, offices, hospitals, hotels, shopping centers, and crowded public spaces. They also enhanced air treatment systems in environments prone to contamination, such as air filtration and distribution systems.

Water Treatment: Since the early 1900s, ozone has been recognized for its efficacy in disinfecting water. Evergreen Ozone systems were designed to treat process waters, sewage, and evaporation towers, and to disinfect drinking water. The technology was used in cities like Amsterdam, Moscow, Paris, and Turin for public water treatment. Additionally, it improved the efficiency of sewage purifiers and reduced the use of chlorine in swimming pools, enhancing health and environmental outcomes.

Food Product Treatment: Ozone technology was applied to extend the shelf life of food products without chemical preservatives, preserving their natural taste and color. This method was particularly effective for cheese and cold cut seasoning, as well as fruit and vegetable conservation.

Technological and Operational Benefits: The systems provided numerous advantages, including the elimination of microorganisms, odor removal, surface disinfection, and the absence of chemical residues.
