The many benefits of resource efficiency

In today’s industrial landscape, there is a growing impetus for actors to enhance resource efficiency, with some pioneers already formulating responses. Heightened awareness of the environmental impacts of resource depletion, pollution, and waste generation is driving this shift, while many also see opportunities for improved competitiveness.

As engineers, we hold a pivotal role in advancing resource efficiency. But how do we achieve this? One crucial avenue is learning from the past. When I entered the engineering scene over 20 years ago, the thumb rule was to over-dimension everything as “that is how we normally do it, and it is good to overdimension for future needs”. This often led to unnecessary oversizing of systems and excessive consumption of materials without clear justification.

Another effective approach is optimizing operations. Finely tuned processes not only yield higher outputs but also produce fewer emissions with reduced toxicity. This optimization is intricately linked to ongoing learning and skill development and efficient utilization of modern control systems.

In this issue, we highlight an intriguing “urban mining” initiative. Finnish pioneers have developed an innovative method to promote resource efficiency through the recovery of metals classified as critical raw materials from electronic waste. Overall, technologies aimed at reclaiming valuable resources from waste streams and repurposing them for various applications are crucial in addressing global resource consumption. Extracting energy from organic waste through anaerobic digestion, as well as repurposing waste materials in construction projects, represents highly responsible examples of engineering fundamentals.

Recently, when a lock on my trusty old luggage broke, I chose to repair it for €40 instead of investing €500 in a new one. While the replacement lock may look different, it serves its purpose perfectly. This small decision reflects a broader mindset of resourcefulness and cost savings.

By adopting such resource-wise practices, we not only contribute to sustainability but also save significant resources and money in the process!

Urban mining pioneers refine rare earth metals from electronic waste

Reading time: 6 min

A Finnish consortium has developed an innovative method for extracting rare earth metals (REEs) from electronic waste, an approach known as urban mining. This not only conserves natural resources but also reduces dependence on China. Despite current legislation not fully supporting the needs of such circular economy projects, the consortium members have diligently pushed the project forward, painting a promising picture for the future.

The increasing significance of critical raw materials

As we pivot away from fossil fuels towards cleaner energy systems, adept utilization and management of materials become increasingly important. For instance, the expansion prospects of many key technologies face constraints due to the escalating demand for critical raw materials. Concurrently, waste and by-products are emerging as noteworthy reservoirs of raw materials, underscoring their newfound significance.

Elomatic’s visualization team leader Marko Jaakonmäki sees digitalization as a key factor in moving towards a carbon-neutral circular economy. He predicts a new divide in the industry: companies that can quickly adopt new technologies will thrive, while those with low levels of digital maturity will lose market share.

From idea to production in less than two years

From idea to production in less than two years – Hailia devised a way to upcycle surplus fish raw materials into delicious everyday food

Reading time: 5 min

The technology developed by Finnish startup Hailia offers an ecological alternative, for example, to tuna or minced meat. It enables the transformation of small pelagic fish or sidestreams from fish filleting, typically used as feed for livestock, into versatile food products. The company’s future plans include entry into international markets.

A transformative shift in the pharmaceutical industry:Resource efficiency with single-use equipment

Reading time: 4 min

In recent years, the global pharmaceutical industry has faced increasing pressure to minimize its environmental footprint while maintaining the highest standards of product quality and safety. One innovative approach gaining traction is the adoption of single-use equipment in pharmaceutical production processes. This shift not only enhances efficiency and flexibility but also significantly reduces resource consumption and waste generation.

Resource efficiency not only underpins eco-friendly business models but also fosters economic viability. A resource-wise approach considers even more broadly the use of renewable resources, the circular economy, well-being, and reduces dependence on limited natural resources. However, sustainable development demands various skills, rethinking, and actions from organizations.
