Technical Development

With nearly 40 years of technology expertise and experiences, CTCI seeks to create a better future with clients using the introduction and research of engineering innovation.  Meanwhile, we keep enhancing our environmental technology abilities so that we can seize the opportunities brought by environmental risks as we develop constructions of related technologies. Since the introduction of green engineering, we have been the pioneer in the engineering industry, increasing the advantages of green technology as one of our sustainable goals, and ensuring that we stay competitive in the future market.

Increasing energy efficiency, saving water, taking care of the ecosystem, and creating a safe working environment are the four essential elements of green engineering. In  the  wake  of  governments  around  the  world pushing  the  goal  of  a  low-carbon economy,  we  are  now  developing  different  kinds  of  high  efficiency, eco-friendly facilities and energy management technologies. We have put them into practice and received great results.

To break through the innovation bottlenecks in today's green engineering, we are committed to finding technical solutions. Simultaneously, we expand our R&D focus from basic technology to technology development, then broadening our discovery into the production management of the whole company to contribute to the future development of the engineering industry.

Usage of Raw Materials

CTCI has always been committed to exceeding the expectations of its clients. In each project, we use accurate calculations to acquire the minimum resources and costs for the construction, preventing waste or use of excess materials and realizing high-efficiency resource management. We make efforts to assess levels of eco-friendliness during the selection of materials. Procurement of eco-friendly materials can reduce resource consumption and pollution. Similarly, we support suppliers who carry out environmental management themselves to encourage development and production of eco-friendly materials.
