Therefore, backed by our practical experience, we are applying innovative methods to provide our customers with high-tech process supply systems in different industry sectors that are moving towards the circular economy. We specialise in the semiconductor industry and will move into the cosmetics industry in 2023. In the future, we expect to expand into other industries as well.
In order to enhance the efficiency of energy saving and waste reduction, Nova Tech has studied the details of each system optimisation, divided the system into design and operation phases, and considered the environmental benefits that can be enhanced in different phases of different systems, and endeavoured to make the system as perfect as possible.
Nova Tech's non-energy engineering technologies and systems involved in climate change mitigation include: gas mixing systems, chemical dilution systems, bleed water combined with reclaimed water systems, chemical waste recycling equipment, aluminium etchant recycling technology, etc. In 2023, the total amount of the above construction in progress will be $3,502 million.
Process Efficiency and Quality Optimisation
Improving resource efficiency and process optimisation has always been a core focus for us. Nova Tech's goal is to provide our customers with highly accurate and stable process systems that improve the energy and resource efficiency of their factories and the life of their process systems. In 2023, we have optimised many of our designs to improve performance. For example, we converted the lighting in our machines to energy-efficient fluorescent lamps, which are expected to reduce power consumption by 75 percent. Through years of engineering expertise, Nova Tech continues to design processes that optimise efficiency and quality for our customers.
Pollution Prevention and Waste Recycling
Pollution prevention, recycling and reuse of waste materials are issues of great concern in recent years. ova Tech aims to achieve circular economy in high-tech processes by utilising its own technologies to reuse waste for its customers and to enhance their ability to properly treat waste and wastewater. Our representative technologies are effluent/reclaimed water systems, highefficiency thin-film oil and gas recovery devices, low-temperature sludge drying technology and high-efficiency denitrification treatment systems.
High-value Energy/Resource Recycling
High-tech factories have many high-value pharmaceuticals, which can cause significant harm to people and the environment if they are accidentally leaked into the environment.
Nova Tech provides recycling and reuse systems for high-value raw materials in customers' processes through its products and technologies, which reduces customers' costs and fulfils its environmental responsibility. Our representative technologies include: chemical waste recycling and reuse equipment, aluminium etchant recycling technology, and high-efficiency thin-film oil and gas recovery equipment.
| Chemical Waste Liquid Recycling Equipment |
The high-tech industry and the manufacturing industry use a considerable number of chemical materials in the production process, leaving a large quantity of waste chemicals after production. We have introduced overseas waste liquid recycling technology, which uses special recycling equipment to recycle high unit-price waste liquids into raw materials that can be reused in the original manufacturing process, thus effectively utilising resources and avoiding wastage. Relevant achievements include: assisting customers in the recovery of
stripping solutions, process cleaning solvents and tetramethylamine in wastewater. We recycle chemicals by distillation and the different boiling points of the target chemicals. Highly efficient heat exchange is also used in the process to efficiently recover heat and reduce energy consumption. This technology can be customised to adjust the recovery rate of chemicals in the process, and the maximum solvent recovery rate can reach over 90%.
In the manufacturing process of panel factories, the photoresist diluent waste liquid is difficult to be recycled due to its complex solvent and photoresist components. Outsourcing the process is costly and the recycling technology has limited performance. In 2023, Nova Tech cooperated with the Industrial Technology Research Institute (ITRI) for the second time to add a new SRS recycling system for a well-known photovoltaic panel supplier, which makes use of the distillation heat method and the characteristics of different boiling points of the subject chemicals to recover the used organic solvent stripping solution for the supplier to recycle and reuse directly in the factory. This not only reduces production
costs, but also achieves waste reduction and reduces transport risks.At the same time, the effective heat exchange efficiency in this process also recovers heat energy and reduces energy consumption.
The design capacity of the recycling system constructed by both parties is 1,200L/hr, with a recycling rate of over 90%, which simplifies the traditional purification unit and saves energy, overcomes the clogging problem of photoresist, and purifies the solvent to achieve the benefit of carbon reduction, and the total project amount reaches $27 million.
| High-efficiency Thin Film Oil and Gas Recovery Unit |
Achieve recycling and improve the air quality
in the factory for customers. Nova Tech has been working with a leading German equipment manufacturer to develop laminated membrane oil and gas recovery technology, which is designed to increase oil and gas recovery and recycling and significantly reduce air pollutant emissions. The technology separates tank oil from clean air, converts the oil and gas into a liquid that can be recycled into the tank, and purifies the clean air for discharge in a combined system of compression, absorption and selective gas permeation membranes.
The system recycles any oil and gas that may escape from the tanks, reduces the proportion of oil and gas that escapes into the atmosphere, and reduces the concentration of VOCs emitted from the tanks with recovery efficiencies of up to 95%. Nova Tech has been working with an equipment supplier to assist the Ciaotou Oil Supply Centre to complete the installation of a recovery system, which is currently in operation. We are currently preparing to apply the same technology to the petroleum brain storage tanks at the CPC Linyuan plant to recycle the oil and gas that may escape from the tanks and reduce the proportion of oil and gas that escapes into the atmosphere. This technology can reduce the concentration of VOC emissions to less than 300 PPM and has a recovery efficiency of up to 95%, which can significantly reduce air pollution emissions and energy wastage.
Nova Tech is actively cooperating with overseas manufacturers in technology development and providing pollution prevention equipment and related technologies to domestic enterprises, assisting customers to add environmental protection and recycling economy equipment, and working with customers to achieve sustainable development and transformation of operations. Nova Tech will continue to improve and mature its technology in the future.
