How COVID-19 affects the climate?

The coronavirus originated in China in 2019 but soon hit the world and damaged the economy. No one could have predicted such an impact on the economy. There are only a few sectors that have not been damaged by the virus. It is too early for conclusions because the virus has not disappeared yet and today we can talk about the current situation and possible consequences.

The potential (and problems) of green roofs

Have you ever gazed upon the cityscape from up high and admired at how the buldings run out of sight? Perhaps you have noticed that in areas where the price per m² is highest in the whole country, there is so much unused space. Unused space on the roofs. Invaluable space, enjoyed by none. As more and more green space in city centres is lost to commercial or residential areas, we lose a valuable part of our environment. Could roofs have role in solving this problem?

Pollution removal with plants and microorganisms

It seems like we are in a never-ending race to match our energy-intensive lifestyles with advancements in pollution management. However, many of these pollutants are not anthropogenic and existed long before the Industrial Revolution. How then, were these compounds dealt with before we came along? The answer lies in the transformative powers of microbes and plants.

Skip the Pizza Box: The Misfortune of Paper in the Fast Food Industry

Who doesn’t enjoy a snack or the occasional take-away with flavour-packed dishes to please our guts and soul? An inavoidable part of dining this way usually includes some sort of packaging and, later, waste. Nowadays, with all the talk about cutting down on the use of plastics and banning single-use plastics to prevent the pollution of waterways and oceans, it seems natural to move away from plastic bags, wrappers, styrofoam and single-use boxes to adopt more sustainable packaging. Most people are probably thinking „paper“ at this point. Well, there’s some bad news...

New diet suggests one burger per week is enough to save the planet

The world is targeting a global warming increase of less than 1.5C by year 2100 but getting there requires changing human behaviour at massive scales. It is currently projected that there will be 10 billion people on Earth by 2050, all of whom need food, shelter, clothes, jobs, etc., and who will also become consumers of many other products and services, altogether generating huge pressure on global resources. But there is a way to become a sustainable consumer without sacrificing too much – and it doesn’t involve becoming a vegan!

Timber houses combating climate change

Last winter was the warmest on record and the outlook for the coming summer is promising to follow in the same tracks. Even though weather isn’t an issue when you’re inside the comfort of your home, climate change is an issue that is threatening both human and natural existence. With increasing CO2 levels and more heat, ocean acidification is posing a growing threat to marine wildlife, meltwater from glaciers is raising global sealevels and shifting atmospheric currents are bound to have a severe impact on agriculture, economy and natural habitats. Consumer activity and population growth are two of the major factors impacting the future of our world, but, surprisingly, wooden houses have the potential to lend a helping hand.

Is there enough oxygen for a growing population?

An adult human breathes about 7 to 8 litres of air in a minute, while resting. That’s roughly 11 000 litres of air a day whizzing through our lungs, or the volume of a container one metre wide and 11 metres long. With deforestation and global population on the rise, is there a possibility there might not be enough oxygen for all of us, eventually?Read more

Morning, June 15th. Cyclists have gathered in the parking lot of the Kroonpress printing plant and are concentrating on the crests and slopes of the 76 km journey ahead. Unknowingly, thousands of people pour themselves a cup of coffee and open up the daily newspaper Postimees, where an A+ label with 66 gCO2 signifies that they'd have to give up 450 m of driving a car to compensate for the emissions.

Where are the lungs of the Earth?

We've often heard that rainforests are the lungs of the Earth, providing us with most of our required oxygen. While it is indeed true that rainforests may produce up to a quarter of atmospheric oxygen, most of it is consumed by the rainforests themselves by degradation of organic matter. Most of our atmospheric oxygen actually comes from the oceans.

The average print consumes a spoonful of water

Water is used in offset-printing to separate the printable areas from the non-printable areas. In addition to water, printing presses use natural gas for the setting of heatset-ink and evaporating excess moisture, while electricity keeps the rollers running. Here's an infographic about the resource consumption per average product at Kroonpress:Read more
