French researchers have concluded that Roundup and other herbicides with the active substance glyphosate, in addition to this, also contain extremely toxic additives. Three questions to Peter Bergkvist, agronomist at the Swedish Chemicals Agency.
How does the Swedish Chemicals Agency react to this?
- This is not news, but an issue that has been discussed for a long time. American researchers have also come to similar results in tests with amphibians that died in direct contact with the agents. There are many indications that it is not the active substance glyphosate itself that gives these effects without surfactants, so-called polyethylene glycol talgamines, which are also present in some glyphosate products.
What about the use of Roundup and similar agents in Sweden?
- Sweden and other Nordic countries have demanded from manufacturers that these surfactants in the products should be replaced. This has led manufacturers early on to launch so-called Bio products in the Nordic region, such as Roundup Bio. They do not contain tallow amines - ie surfactants. These Bioproducts have been marketed as less environmentally hazardous and have performed well in the Nordic market.
How do you keep your own weeds in order?
- There are many preventive measures and non-chemical methods. The simplest is the weed hoe. Weeds often grow in gravel passages, and there it is easiest to chop them away.
Take the fight weeds
One of the most well-known herbicides is strongly questioned even though it is still sold. But why resort to poisons when there are other ways?
Glyphosate, which is the active substance in, among other things, the herbicide Roundup, is a much-discussed agent. Right now, there are several different proposals from both the Swedish government and the Swedish Chemicals Agency to limit use.
However, none of these have yet been decided. In 2018, it will still be allowed to sell Roundup, which is the most common glyphosate remedy for the home garden.
- Every year, 600-700 tonnes of glyphosate are used in Sweden, says Peter Bergkvist at the Swedish Chemicals Agency. Of this, about 10 tonnes are used in home gardens.
The inspectorate wants to reduce this use. An environmentally friendly alternative to Roundup are products that contain geranium acid, they have the brand Finalsan and are called Weed Effect and Moss Effect.
In recent years, another method that is said to be completely environmentally friendly has also begun to be used. 98-degree water! It is effective against all types of weeds, moss and algae. Plants with bark are not negatively affected by the heat, nor are their roots. So far, this is mostly used in professional contexts, but hopefully solutions for ordinary homeowners are on the way.

Straw shortening agents have long been banned in wheat, barley and oats
In 1987, a ban was introduced on straw shortening agents in cereals, except in rye that has weaker and longer straw.
In 2011, however, permitted cereals were expanded to include wheat, barley and oats.
However, the levels of straw shortening agents that Testfakta has discovered in the products are below the permitted limit values and according to the National Food Administration there are no health risks for humans.
According to Testfakta, however, it is suspected that the substances are suspected to have a negative environmental impact on birds and mammals and the EU is in the process of making new evaluations of the substances.
The outward face of the 100th anniversary association
Despite the fact that he has begun to step up his commitment, he is still closely associated with Oskarshamn's Swimming Club.
Peter Tidäng has spent most of his adult life in the swimming pool and for long periods has been head coach of the now 100-year-old club.
He does not have time many meters into the swimming pool before his attention is called from the pool. The OSS-educated talent Erik Nicklasson, who now competes for Jönköpings Simsällskap, is visiting his former hometown and would like to exchange a few words with his old coach.
- This is something that is so fun! I have always loved working with young people and seeing how they develop and have fun memories of their sports time, Peter states with a smile.
His own career began in the mid-1960s. After showing his forefoot in team swimming in the then school championships, he was persuaded by some classmates at Gröndalskolan who were already involved in the swimming club to start training. Peter also does not hide under a chair that all the girls in the swimming club also attracted.
Oskarshamn's first swimming hall was then only a few years old. Despite this, the summer training was located at Gunnarsö and the pool between the bridges at the jumping tower, which had both starting pallets and divided courses.
- It was not always so fun when it was gray, overcast, rainy and only 17 degrees in the water.
In addition to swimming, Peter also played football and handball and had a hard time choosing. In 1971, however, he decided to invest in swimming and in connection with that also became head coach of the club and eventually became part of the OSS men's team.
- In 1973, I moved into military service and after that UN service for a few years. Then I started studying physiology in Helsingborg, among other places. When I was back in Oskarshamn in the late 70s, I had lost touch with swimming and instead chose to invest in handball where I trained as an elite coach, says Peter Tidäng.
In 1985, he was contacted by OSS, who had lived a modest life for a few years.
- There were some enthusiasts, Kennet Holmberg and Bonny Hagberg, who had kept the club alive for many years. Together with, among others, Nils-Gunnar Johansson, Lars-Göran Johansson and Calle Östman, we were a wonderful group that quickly managed to produce a number of talented swimmers at the Swedish Championship level.
With Tidäng as head coach between 1985 and 2001, OSS achieved great success and periodically was one of Småland's absolute best swimming clubs.
- Dan Johansson, now Tvingsjö, Anna Loman and Jenny Johansson were some of all the talents I was with and nurtured in the club. Likewise all
talented girls who were born in the early 80's. I also trained Niklas Gustafsson as a youth.
From 1994 and 20 years onwards, Peter was also involved in Smålands Simförbund's efforts to produce talented young people of SM class. During roughly the same period, he was also employed as bath manager in the old swimming pool and then as lifeguard and safety manager in the new swimming pool at the Arena until his retirement a couple of years ago.
- As for my coaching assignments, I left OSS in the early 2000s and was instead involved in Hultsfred's Simsällskap's investment for several years which, among other things, resulted in several youth and junior national team swimmers, says Peter.
After Peter Bergkvist took over as head coach of Oskarshamns Simsällskap around 2010, Tidäng eventually returned to the club as an assistant. Nowadays he has no official coaching assignments but is often on site in the swimming pool to help and support the club's active members. He sees a bright future.
- It is good regrowth and many talented young people in the club with potential who have the future ahead of them, Peter states.
As a club's true veteran and outward face, he is also one of the spider in the web ahead of the US 100th anniversary which will be celebrated on 9 September.
- We start with mingling in the old swimming pool, now Hotel Ett, and then continue with banquet and dinner at Forum. We hope that as many as possible take the opportunity to celebrate. Only a few associations in the city have reached this respectable age!

IMPACT IN US 100-YEAR-OLD HISTORY:
• On 27 June 1917, Oskarshamns Simsällskap was formed at a gathering in the old cold bath house on Muddern next to Brännvinsholmen. Mayor Allan Grauers was elected first chairman.
• Engineer Ivar Lövgren was hired as swimming teacher and Henrik Nilsson as deputy swimming teacher.
• DM 1920 was organized in connection with Badholmen and Allan Grauers won a third prize. By the way, he is said to be the first OSS who learned the new way of crawling.
• In 1943, OSS built a wooden jumping tower on Gunnarsö with a grant of SEK 800 from the Swedish Swimming Association. The jumping tower was replaced in 1958 by a new one in concrete.
• Billy Pettersson took silver in the 200 meter breaststroke at JSM 1943.
• In November 1960, the swimming pool in Oskarshamn was inaugurated, which was an important milestone in OSS history.
• In the late 60s and early 70s, Thomas Ternstål and Eva Lott Kihlberg were among some of OSS 'great swimmers.
• In 1992, OSS was one of Småland's best swimming clubs and celebrated 75 years as an association. The successes continued throughout the 90s
• In September 2006, the new swimming pool at Arena Oskarshamn was inaugurated. It is still Småland's only 25-meter pool with eight lanes.
• 2017 celebrates Oskarshamns Simsällskap 100 years. The club has about 400 members and is led by chairman Pär Henrysson with Bengt Svensson as head coach.
The new railing stops both large and small cars
A new bridge railing that can stop crashing trucks has been developed in the project for the new bridges in Rotebro. The railing is the first of its kind in the world.
Very heavy traffic passes over the bridges on the E4 in Rotebro, at the same time as both car traffic and train traffic move under them. If a truck falls from the bridges, it could be a disaster with lots of deaths. Therefore, the idea arose in the construction project to develop a new railing with higher capacity than those that are usually set up.
The big challenge was to develop a railing that is strong enough to stand on a stool for a 38-tonne truck, while at the same time being soft enough so that a small car is not crushed or bounced out of traffic.
This has been solved by constructing the railing with longitudinal steel pipes that will receive the forces from a truck and distribute them down into the posts over a longer distance. To stop a small car in a good way, the posts have been fitted with a steel plate that collapses and absorbs energy in the event of a crash.
- At the same time, it was a problem to make the construction very narrow so that it can fit on the concrete, says Anders Hamrin, marketing manager at Saferoad Birsta.
The railing is made of steel with varying qualities in different parts.
- We prefer materials that can be stretched a lot before it breaks. We have been working for many years to get the right steel quality, not too strong and not too thick, says Anders Hamrin.
The railing in Rotebro is the first bridge railing in the world of its kind, ie the first that can withstand the collision of a truck and at the same time makes it possible for motorists to see the landscape on the side of the road.
- The bridge railings that exist in Europe are large ugly constructions. This is the first in the world with pipe profiles so that you can see through the railing, says Anders Hamrin.
The bridge railing is also the first in Sweden that has been tested to withstand a collision with a 38-tonne truck.
- The standard in Sweden is otherwise that the railings must withstand a 13 ton city bus.
The Swedish Transport Administration's head of building technology, Lahja Rydberg Forssbeck, still believes that safety is good with the railings that sit on Sweden's bridges.
- The railings we have on our bridges today have proven to be able to collide with heavy trucks in a good way, she says.
After the installation in Rotebro, more Swedish bridges have been fitted with the new railing. It is also planned to be used along the Mälarbanan and Stockholm Bypass.
Can handle 38 tons at 65 kilometers per hour
The new bridge railing is called Birsta 3P H4b.
It must be able to hit a truck of up to 38 tons at a speed of 65 kilometers per hour and an angle of 20 degrees.
It must also be able to hit a small car of about 900 kilos at a speed of 100 kilometers per hour and a 20 degree angle.
The railing has been developed by Saferoad Birsta, NCC, the Swedish Transport Administration and the bridge designer Centerlöf & Holmberg.
3d technology and prefabricated in innovative buildings
We have taken a closer look at four projects that take advantage of the possibilities of industrial wood construction. Only conditions and methods differ.
»TREET«, THE WORLD's HIGHEST wooden house, sits with its 14 floors next to the Puddefjord bridge at Damsgårdssundet in Bergen.
"The tree" should not only be rooted in the long history of the Norwegian wooden tradition, but also fit into a modern Scandinavian design tradition with a focus on good materials, solid craftsmanship and smart design, says chief architect Per Reigstad.
Three types of wooden structures have been used, with the load-bearing structure laid on the outside. The framework, which enables the high height, is made of glulam and is protected by glazed balconies on two sides. Inside, all shafts are made of KL wood.
The apartments are delivered as almost ready-to-move-in modules, volume elements, and were stacked on top of each other, four floors at a time. On floors five and ten, two platforms were built, reinforced with three-meter-high glulam beams, which were anchored in the supporting system.
- The largest modules are 5.4 meters wide. It contributes to the efficient use of modules in relation to floor plans, says Per Reigstad.
The entire construction is 3D-explored and digitized with a high degree of CNC production. The supplier already participated during the exploration to create a building adapted to the deliveries and not the other way around.
Clear communication has been a must. Per Reigstad attributes a large part of the success to the open neutral file format ifc, which enables the exchange of information between CAD programs and other software.
- It has been an exciting and educational process. The collaboration has worked excellently. Since a high degree of innovative solutions has been required, it has been necessary to think interdisciplinary.
3D TECHNOLOGY ALSO PLAYED a big role when the Pulpit Rock in the scenic Strand in Norway was created. The 1,100 square meter hotel was created when the Stavanger Tourist Association wanted to expand the range on site with a restaurant and more comfortable accommodation. Above ground, it is almost entirely made of wood. With a roof design that alludes to the surrounding terrain formations, it blends well into the surrounding landscape.
The Holz100 system has been used here. It consists of several layers of wooden joists held together by wooden dowels. In total, the house consists of 400 floor elements. All construction in interior walls, exterior walls, covers and ceilings is in solid wood.
- We wanted to use this technology for the environmental and aesthetic properties. The robust wooden constructions are exposed and give associations to traditional Norwegian architecture, says Dag Strass at the responsible architectural firm Helen & Hard.
The main shape was designed and modeled in 3d. The basis for the element drawings was produced in collaboration with an engineering company. Based on this, the producer created drawings and 3D models of the individual elements, which were seen by the architects before they went into production, says Dag Strass.
- Thanks to the good cooperation, we were able to go in and modify the construction of some of the elements, to solve static challenges and create the characteristic expression in the restaurant area.
- Prefabrication gives the architect better control over the result, as geometry and joints can be examined in 3D in advance. You do not become as dependent on the craftsmen's accuracy and ability to read drawings, Dag Strass concludes.
LANDESGARTENSCHAU EXHIBITION HALL in Schwäbisch Gmünd near Stuttgart is an architectural prototype and part of the research project »Robotics in wood construction«, which the city university runs together with a number of project partners. It is the first building with a main structure consisting of prefabricated, robot-made book plywood boards, 243 to be exact. 12 cubic meters of beech plywood was used to enclose a gross volume of 605 cubic meters.
Insulation, waterproofing and facade cladding have also been prefabricated digitally. All wood material was grown, processed and manufactured within a radius of 250 km from the construction site. The assembly took only four weeks.
Three of the university's institutes - the Institute for Computational Design (ICD), the Institute of Building Structures and Structural Design (ITKE) and the Institute of Engineering Geodesy (IIGS) - have jointly developed the innovative lightweight construction system.
The panel system constitutes both the building's structure and its casing. The loads that arise around the edges of the boards are effectively transferred through the 7,600 individual finger joints, which ensure the stability of the building, explains Professor Achim Menges at ICD.
- This new form of wooden construction makes it possible to use only 50 millimeter thick plywood boards.
The idea is to show the possibilities with digital architecture, how design calculation, simulation and manufacturing methods can be used to create resource-efficient constructions of wood. The emphasis is on developing a coherent digital chain throughout the process.
ICD's design calculation tool has made it possible to include the material's properties and manufacturing parameters in the design process. Instead of drawing each disc manually, simulation is used to automatically find the correct shape. Without the robot technology, the complex structure would have been impossible, emphasizes Achim Menges.
- Compared to conventional prefabrication methods, this manufacturing technique enables much greater precision.
NEW DIGITAL PRODUCTION METHODS also form the basis for the innovative Copenhagen company Eentileen's (1: 1) vision to blur the line between the architect and the builder. The idea is to offer a tailor-made building system. "Print your house," is the motto. Eentileen offers everything from standard to special solutions. Common to all constructions is that they are pre-produced in the factory or during construction with a CNC machine. Robots are also being used to an increasing extent. Eentileen's first digitally produced house, Villa Asserbo, outside Copenhagen, was printed by a large CNC printer on 820 plywood boards.
The advantage of Eentileen's prefabricated elements is that they are small and flexible. They are produced directly from a 3D design file and can be easily adapted to the design. A direct connection between design, production and assembly guarantees high precision and error.
The standard segment offers a number of ready-made module solutions to choose from. The premium segment can be designed according to your own head and still be delivered as a kit ready to assemble, with windows, doors and wall and facade cladding already in place. Other architects can easily create their own solutions.
Eentileen uses exclusively wood in its construction. The wood fiber insulation handles both moisture and heat. It provides a good indoor climate that does not require a moisture barrier, Frederik Agdrup explains.
