By choosing Cajo’s sustainable marking systems, forward-thinking manufacturers can save costs and the environment.

It is a fact that technology cannot sustainably continue to advance at the expense of the environment. Sustainability, the conservation of nature and resources for vital ecological balance, is a crucial core value of Cajo’s additive-free product marking solutions. Cajo’s patented laser technology has been proven to be over 90 % more environmentally friendly marking solution than inkjets traditionally used in the manufacturing industry.

Cajo addresses global sustainability challenges by promoting the goal to reduce the use of chemicals, as well as reducing material waste and energy consumption. For instance, energy efficiency has been a priority in the EU. The Europe 2020 Energy Strategy and Waste Framework Directive (Article 4) set the goal of a 20 % improvement in energy efficiency within the EU. Also reducing the amount of waste generated at the source and reducing the hazardous content of that waste is regarded as the highest priority according to the Waste Hierarchy established in the Waste Framework Directive (Article 4). Cajo’s technology is a step forward in achieving both of these environmentally high goals.

Moreover, the European Commission recognises climate change and environmental degradation as an existential threat to Europe and the whole planet. To overcome these challenges, the European Green Deal has been established in 2020 to transform the EU into a modern, resource-efficient and competitive circular economy.

With ecological Cajo lasers sold to and running in over 60 countries around the world, Cajo Technologies provides the global manufacturing industry with the necessary tools for environmentally friendly production while also ensuring companies keep their competitive edge.

Choose Cajo’s green technology and lead the way to a brighter tomorrow.



This is a very unresearched topic so far. In 2020 a study was conducted with Macon Ltd. regarding the carbon footprint of laser labelling. Below you’ll find a short conclusion on the carbon footprint of a laser printer versus inkjets. You can download the full study from the link below.

The study was carried out aiming to define the carbon footprint of industrial labelling with two alternative methods: 1. Cajo Technologies laser labelling and 2. ink labelling. The calculation included the emission of energy and chemicals, assuming an annual workload of 1697 hours. The carbon footprints of the labelling options are 43 kg CO2 eq per annum for Cajo and 501 kg CO2 eq per annum for inkjet. This result indicates that  Cajo`s chemical-free technology enables over 90 % reduction of the carbon footprint of industrial labelling.

The Key Flag is a sign of Finnish work. The Key Flag symbol is awarded by The Association for Finnish Work in recognition of a product made in Finland. In addition, the right to use Key Flag Symbol can be awarded to products with a minimum domestic content of 50 percent of its break-even cost. The calculation takes into consideration all costs related to the product.

We are proud to say that Cajo Technologies’ laser marking equipment is awarded by the Key Flag

Cajo has a patented laser marking method to implement color and traceability markings to metal sustainably without using additives. Our laser marking systems and software are developed and designed by our own product development team. Our devices are developed and manufactured in Northern Finland, in Kempele headquarters – utilizing domestic subcontractors remarkably.
