How is Cathay implementing digital enterprise now? 

In distant Wusu, Xinjiang, China, a digital factory is quietly rewriting the future of the bio-manufacturing industry. While 76% of manufacturers believe an 'Industry 4.0’ strategy will increase their competitiveness, only 57% say they are prepared for digital transformation and only 6% have a clear roadmap* (Source: McKinsey). The few who take this leap are those with the vision and courage to step into the unknown and tap into a limitless potential. (*Source: McKinsey Quaterly, May 2017)

Tackling the challenges

The digital factory: the key to unlocking the potential of a growing industry

Cathay produces polymers – an essential element for various chemical products – with bio-manufacturing, using renewable raw materials like corn instead of oil. Expanding the business meant reproducing a highly complex and sensitive laboratory process at an industrial scale. Cathay needed a technology partner who could provide the full potential of digital manufacturing. Consistency, repeatability, guaranteed quality and greater efficiency – this was the secret to Cathay’s successful expansion, and the key to a new future for the bio-manufacturing industry.

Cathay’s Wusu plant adopts Siemens’s complete digital factory solution, covering the entire lifecycle of the plant in design, construction, operation and maintenance, enabling Cathay to fully upgrade every step of its process, from R&D to production.
