The printing house of Otava Book Printing Ltd. in Keuruu, Central Finland, has been printing books for more than a century. A Finnish publishing company, Otava’s books are manufactured domestically, responsibly, effectively and in a way that respects the environment.

A significant part of the paper and board used is of Finnish, certified quality. Waste recycling is a fundamental part of the company’s operations; any waste from production is carefully sorted where it is created. 97 % of by-products from production is exploited for future use, of which 5 % is energy waste. Less than 2 % of all the waste generated ends up in a landfill.


With its operations guided by the ISO 9001 quality certification and the ISO 14001 environmental certification, the Finnish company Greedled was a natural choice of partner for the lighting renewal at Otava’s printing house. Greenled’s luminaires are made in Finland and are 100 % recyclable. Together with smart lighting control, the LED lights generate significant energy savings for the business operations while also decreasing CO2 emissions.

With the new lighting, the energy savings of the printing house were 75 %, a decrease of 91 tonnes in CO2 emissions compared to the old lighting.

Marko Silventoinen, Managing Director at Otava Book Printing Ltd., explains that reducing the company’s carbon footprint was one of Otava’s main reasons for switching to Greenled’s lighting system.

However, it is just as important that with this solution we can invest in occupational safety and comfort. Everything we do at Otava starts with people.”

Another factor in Otava’s choice of partner was domestic quality – both Otava Book Printing and Greenled have the Finnish Key Flag Symbol, a sign of production and end products of domestic content.

In addition to the new luminaires, the printing house now has a smart OSRAM ENCELIUM™ lighting control system to facilitate and visualise control, automatisation and energy consumption. ENCELIUM™ is the winner of the Lux Award 2017 in the Controls Product of the Year category. In Finland, the product is sold exclusively by Greenled.
