Sustainability 4.0: eco-efficient with alloy free blocking and MES

By Michael Kreis, Satisloh





Besides the well-known KPI´s like throughput, lead-time or yield it becomes more and more important to operate production facilities in a sustainable and eco-efficient way. Are these contradictory requirements or maybe even complementary tasks? In general, waste generation, as well as water and energy consumption, are the biggest hurdles in achieving a green lab operation.

This talk outlines the most promising levers to make an ophthalmic lab more eco-efficient by avoiding waste as well as reusing energy and water. The biggest opportunity to run a production in a sustainable way lies in the optimization of throughput and yield. Keeping machines running and producing quality lenses in the first pass will reduce waste generation and consumption of energy and water per good lens dramatically.

Key to leveraging these potentials is the use of green technologies like next generation ART blocking as well as smart routing and scheduling with MES. To get the right job at the right moment to the right machine is crucial to maintain high productivity and therefore high efficiency. Even in smaller labs it is almost impossible to do this manually and optimize the usage of the equipment at the same time. Every waste – no matter if unused machine time, scrapped lenses or excessive use of materials – will also create an economical loss. Automation with MES based software routing and the use of green technologies are therefore not only eco-efficient but also help a lab’s profitability.
