Despite the uptake of digital tools, only 59 percent of manufacturers cite improved sustainability as a reason to digitalize their operations. However, digitalization’s potential extends far beyond its perceived applications. Data collated by the Association of Swedish Engineering Industries (Teknikföretagen) emphasizes the importance of digital tools in achieving sustainability goals—leveraging IT technology in other sectors, such as manufacturing, has the potential to reduce total CO2 emissions by as much as 20 percent.
Increasing digital tool use is vital to aligning manufacturing activity with the Paris Agreement, increasing resource efficiency and, crucially, reducing waste. Globally, industrial waste is almost 18 times greater than municipal solid waste, according to the most recent data from the World Bank. All manufacturing facilities generate waste, much of which could be avoided.
Overproduction and defect output are two of the most common contributors to waste generation. Facilities running on legacy technologies that lack the sophistication to deal with the challenges of modern-day manufacturing are far too common. However, this doesn’t mean that manufacturers should accept generating huge waste as unavoidable. Industrial waste must be reduced, and data can play a key role in achieving this—if manufacturers know what to do with it.
Every manufacturing facility, regardless of its size, complexity or age, generates a significant amount of data every day. In a smart factory, this data includes everything from equipment performance to product quality and is collected via sensors installed on each machine. Starting small, with each individual machine’s data, is the first method of reducing waste on a large scale.
Small changes to individual processes accumulate and together have a huge impact on operational efficiency. Collecting data from machinery on the shop floor and analyzing it allows manufacturers to monitor processes and act. Manufacturers can then use this data to optimize individual machine processes by detecting inefficient processes, streamlining production and logistics planning and predicting upcoming maintenance needs. By making several smaller processes more energy efficient, data can be used to control—and reduce—overall energy consumption.
Energy inefficiencies can be identified in real time, giving manufacturers the opportunity to identify potential reasons and solutions. For example, when looking at energy consumption data, manufacturers may discover one piece of equipment that uses significantly more energy than others. Manufacturers can then identify the cause of increased power consumption and implement improvements to streamline machine efficiency.
Continuously analyzing data in real time can also help streamline machine maintenance. Data analytics can identify upcoming problems before they happen. If a machine experiences a problem or a change in performance, it may start to produce parts that are not fit for purpose, which would ultimately end up as waste. Data on machine performance can help to identify minute changes in machine behavior as soon as they occur, so that engineers can carry out predictive maintenance before multiple defective products are produced.
The CoroPlus suite of products in the Data Driven Machining offering from Sandvik Coromant, helps manufacturing organizations improve efficiency, reduce waste, and increase productivity. The CoroPlus Process Control monitors machines in real time and triggers actions in accordance with programmed protocols. If specific, predetermined issues occur, the solution automatically triggers a correctional action, e.g., stopping the machine or replacing a worn cutting tool. Conducting maintenance in this way improves operational efficiency by as much as 89 percent and reduces waste by allowing manufacturers to assess data, monitor machine performance, and identify faults before they occur.
Data produced by conducting life cycle assessments (LCA) can also help reduce waste. An LCA assesses the environmental impact of a product at every stage of its life span by considering how a product’s raw materials are extracted, the quantity of resources required, the materials and energy used during manufacturing, packaging and distribution, the impacts of the product’s functional use, and the waste and pollution created at the end of the product’s life.
By considering every single step of the product’s life cycle, an LCA leaves no stone unturned. Once an LCA has been completed, manufacturers can identify big sustainability flaws in a product, evaluate the sustainability of products still in development, and design new, more sustainable solutions.
However, it is not just the products themselves that must be considered, but also their packaging. Packaging is necessary but raises many environmental concerns due to its demand for resources. The problem is also shared globally. In the U.K., nearly 44 million tons of packaging waste are produced annually by commerce and industry, while 28 percent of total municipal solid waste in the U.S. is attributed to packaging.
Sandvik Coromant recognizes the problem with packaging, even for products like cutting tools, and recently launched its package selector application (PSA). The PSA uses data to analyze a 3D CAD model of the Sandvik Coromant product to be packaged, identifies its critical points, and uses an AI algorithm to recommend the smallest amount of packaging possible. This improves the LCA of Sandvik Coromant’s tools by reducing packaging waste produced for their distribution to manufacturers.
Data can also be used to facilitate a closed loop manufacturing chain, where waste from one process is used as a resource in another. This promotes a circular manufacturing economy, where waste is minimized as much as possible through continuous reuse.
Using data from an LCA, along with machine data, manufacturers can improve the efficiency and circularity of their products through constant product and process improvements. Efficiently implementing a production system of this kind requires a robust data strategy. To create a strong data architecture, manufacturers need a digital infrastructure that can easily synchronize operations, potentially across several locations, and identify opportunities to utilize waste that would otherwise be in silo. Sandvik Coromant’s CoroPlus suite of machine connectivity and sensor embedded tool solutions makes digital machining accessible to manufacturers, equipping them with the “close to cutting-edge” data needed to make use of their waste resources for more sustainable operations.
Data can seem overwhelming at first—with such vast quantities available, it can be hard to determine what to do with it. However, with the correct strategy, it can prove a valuable tool for reducing industrial waste by improving efficiency, enabling predictive maintenance, inspiring innovative product development, and streamlining resource management across machines, facilities, and even entire companies.
