221 Series Green Range

WAGO Splicing Connector with Levers – Green Range

Nothing is too small to positively impact our environment. Therefore, we have reimagined one of our best-known products: the 221 Series Splicing Connector.

A variant made partially from bio-circular and recycled plastics has been created to help keep existing resources in circulation. This connector provides a more sustainable foundation for the installation from the very start.

Your Benefits:

Plastics made in part from post-consumer recycled material (e.g., recycled PET bottles) and bio-based industrial and household waste (bio-circular)
Reduced consumption of fossil resources by keeping existing resources in circulation
Same quality and certifications as the 221 Series Splicing Connector

Sustainability Has Many Levers – Mission Green Range

As an industrial manufacturing company, we rely on many resources, including energy and raw materials like plastics. Traditional plastics are derived from carbon compounds found in oil and natural gas – non-renewable resources that contribute to climate change and environmental pollution.

To reduce our dependence on newly produced plastics, we have redesigned one of our most popular products. For the past year, the 221 Series Splicing Connector with levers has been available in a new version made from partially bio-circular and recycled plastics (see FAQ). We named it the WAGO Green Range Splicing Connector with Levers. This connector is a key step towards sustainable development, as every significant change begins with the first small step.

Mission Green Range – What Do We Want to Achieve?

In early 2022, the WAGO Green Range Splicing Connector with Levers started its journey through our company’s “Kickbox” innovation program. The result was the introduction of a connector made of partially recycled and bio-circular plastics. After just one year on the market, we want to think further. Through the Green Range Mission, we demonstrate our commitment to continuously working towards more sustainable materials to reduce our environmental impact.

Our mission is to identify and set in motion the levers for a sustainable and resource-conserving product design. However, not everything can be implemented immediately – it’s an ongoing process. Sustainability has many levers. We are gradually learning how to utilize them more effectively, because we firmly believe that this is the future!

The Path to Greater Sustainability

1 Year of the Green Range: Key Insights and Learnings

The Green Range Splicing Connector with Levers marks its first anniversary! This milestone provides an excellent opportunity to look back and reflect. What progress has the Green Range made over the past year, and what valuable lessons have we gained?

We have learned that sustainability is complex and also entails new challenges and demands for all participants, leading to many questions. We want to tackle these together and support you in doing so.
We have conducted a life cycle analysis (LCA) to evaluate the environmental impacts of our product. This analysis aimed to determine how we could further improve the 221 Series Green Range and understand the environmental factors involved.
Our goal was to assess the impact of keeping raw materials in circulation and recycling them. This is precisely what we do with the partially recycled and bio-circular plastics used in the 221 Series Green Range.

Previously, the savings in CO₂ emissions were only available at the single plastic level. With the LCA, we found that we save about 40% CO₂ emissions on the plastic level compared to the classic 221 Series Splicing Connector with levers.
Additionally, copper and spring steel contribute significantly to the remaining CO₂ emissions. In this regard, the key factor is the recycling percentage during melting. The metals we use already come from sources using the highest possible percentage of recycled materials while achieving the same quality standard. The supplier industry is continuously working to reduce CO₂ emissions through recycling and energy-efficient processes. We want to profit from the advances through a close exchange with the supplier industry, thus striving to accelerate CO₂ reduction.
In addition to materials, we are also continuously working to reduce CO₂ emissions related to our in-house processes. Thus, we strive for lower emissions during in-house production through our power consumption and the continuous optimization of our production processes, such as injection molding, punching and reducing rejects.
It is also important to note that an LCA represents a snapshot in time. It is influenced by primary data, evaluation methods and system boundaries, which can change dynamically. Therefore, we focus on our own improvements rather than comparing ourselves to others. We are committed to constantly improving, and we stand by that commitment. After all, the principle still holds: Nothing is too small to have an impact.

The Future at a Glance:

The Same Quality Made from Increasingly Sustainable Plastics

Our well-known connector with orange levers has long incorporated regranulate-based plastics. However, with the WAGO Splicing Connector with Levers Green Range, we’re going further. We continue to circulate existing materials using a combination of bio-based and recycled materials.

We process plastic waste generated during the production of plastic parts internally and generally reuse this regranulate in producing plastic parts. This is how we strive to minimize our plastic waste.
The WAGO Splicing Connector with Levers Green Range features a conductor cross-section of 4 mm², is made up of 77% bio-circular polycarbonate (housing) and at least 27% recycled PBT (lever). The PBT in the 221 Series Splicing Connector with levers (6 mm² conductor cross-section) and the 221 Series Green Range Inline Splicing Connector with levers contains approximately 26% bio-circular plastics.
Same quality: Both connectors meet the same technical standards and certifications, making them suitable for the same applications.
WAGO's Green Range Splicing Connector with levers is ideal for anyone looking to produce or construct more sustainably.

That's in the Connector

Packed in Grass Paper

Not only does the splicing connector use more sustainable resources, its packaging also follows suit. WAGO pays attention to the materials used and the associated environmental footprint when it comes to packaging, too. WAGO’s Green Range Splicing Connector with levers is packaged in grass paper, a more sustainable alternative to 100% recycled paper. Grass paper is made from up to 30% grass fiber and nearly 70% recycled paper. Grass paper production emits less CO₂* and consumes less water** than pure recycled paper production. In addition, its impact on biodiversity is about 28% lower since the grass fiber comes from ecological compensation sites for development or fallow agricultural land. By law, these sites must be mown several times a year, and the grass clippings go into grass paper production.

*Approx. 5.6% reduction in CO₂ emissions **Approx.11% lower water consumption

FAQ

Sustainability is gaining increased importance in social and legal discourse. This is also due to the fact the effects of climate change are becoming more prominent. National and supranational objectives provide the direction, for example, for climate protection goals. Regulatory requirements also have an increasing impact – including the Supply Chain Due Diligence Act and the upcoming EU requirement for sustainability reporting. But regardless of these external developments, we are also convinced that sustainable business is the foundation for long-term success and an indispensable element of corporate responsibility – an attitude that the CEO, management and shareholders fully support. WAGO has participated in the UN Global Compact sustainability initiative since 2012 [1], an endeavor by companies committed to universal sustainability principles, and has voluntarily reported its progress since then. In 2021, we launched our sustainability strategy process with a comprehensive sustainability analysis to establish sustainability in the company in a binding and extensive way; during the process, we set ambitious goals.

As an industrial manufacturing company, we need resources and energy to produce and operate our products. We recognize that this makes us part of the problem when we consider future challenges. Therefore, it is all the more important for us to be part of the solution and assume responsibility as a company and an employer in an integrated way. For this purpose, we have strategically anchored environmental and social sustainability within the WAGO structure. Every entrepreneurial decision is evaluated in coordination with the sustainability program, and the entire supply chain is considered. Nothing is too small or insignificant on this path; every step in the right direction counts. This attitude also allows us to empower and motivate our employees. We also wish to report on successes and failures transparently.

Until now, we have been processing plastics made from fossil raw materials. Part of the fossil molecule chains in the PC and PBT plastic types are replaced by polymers obtained from bio-based residues from industrial and household use and post-consumer waste. With WAGO's Green Range Splicing Connector with levers, we now use plastics made partly from bio-circular material (77% polycarbonate) and recycled material (at least 27% post-consumer PET in PBT). In addition, we package the connectors in a carton made of grass paper. Copper, spring steel and the production are identical to the standard 221 Series Splicing Connector.

The polycarbonate we use is certified under the “International Sustainability and Carbon Certification System” (ISCC Plus). ISCC PLUS is an international certification system that applies to the bioeconomy and the circular economy for food, feed, chemicals, plastics, packaging, textiles and renewable raw materials originating from a process with renewable energy sources. The mass balance is one of the chain of custody options that ISCC PLUS could certify (see “What is mass balance?”). ISCC Plus certification allows complete traceability of the materials used throughout the entire supply chain. In our case, the mass balance ensures that 77% of the PC material is linked to bio-circular materials. This means that 77% of the raw materials linked to the biogenic residues (bio-circular) are used for PC production. These are residual materials from industry and households, such as tall oil, used fats and by-products from cooking oil production.

The bio-circular raw materials are imported with the fossil raw materials at the beginning of plastic production. In production, the bio-circular raw material mixes with the fossil raw material. The mass balance approach then enables the various raw materials to be mathematically assigned to specific plastic materials.

Thus, mass-balanced materials are materials for whose production biobased raw materials or precursors were demonstrably used materially (i.e., not energetically), without their biogenic carbon being reliably detectable in the end product. The proportion of certified renewable (bio-based) raw materials is assigned to specific products based on the assignment requirements.

At least 27% of the new material is made from post-consumer PET bottles diverted from the waste stream. PET bottles (Ocean Bound Plastic/Land Source) are discarded into the environment worldwide, polluting nature. This pollution occurs in waterways, coastlines, beaches and other areas, particularly where recycling systems are lacking. To convert PET bottles into polymers, they must be collected, cleaned and shredded. The shredded bottles are then re-polymerized into PBT through a chemical upcycling process known as “depolymerization,” which involves adding a solvent, petroleum-based molecules, glass fibers and flame retardants. The result is a recycled PBT that retains the same technical properties as conventional PBT.

Products made from recycled bio-based residues are referred to as bio-circular. For example, the PC material used in WAGO's Green Range Splicing Connector with levers comes from residues such as forestry by-products, edible fats or the production of edible oils.

The metals used, such as copper and spring steel, remain the same as in conventional products. These metals are predominantly sourced from recycled scrap.

Non-scrap components included are crucial alloy elements required to maintain our products' technical capabilities and quality.
