Clean drinking water is a precious commodity. The central Swiss company Alois Bader AG used Leister extruders to produce a recently installed reservoir for supplying drinking water to the community of Giswil in the canton of Obwalden.

​In Egypt, the largest wastewater treatment plant in Africa, Bahr Al-Baqar, is being built. Due to drought and rapid population growth, there is an urgent need to treat agricultural wastewater and recycle the clean water obtained. In this article, you will learn what equipment from Leister was used in this civil engineering project.

​At first glance, nothing. But there are similarities. In this blog post you can find out which and how Leister extruders are used for welding the huge PE tanks for the sustainable pike-perch breeding "Basis 57" in Erstfeld, Switzerland.

The high-performance plastic boats were manufactured in South Africa with air-heated, hand extruders from Leister Switzerland.

The following article explains how the boats are manufactured, what makes them special and what they are mainly used for.

Mexico, a country stretching from Guatemala's subtropical climes in the south up to the dry Arizona desert in the north, is continuously confronted with water shortages as well as polluted subterranean and surface waters. 

Consequently, wastewater treatment has the two-fold objective of preventing the contamination of water bodies, while at the same time using waste water to generate purified water, which can be used for irrigation and/or sanitary purposes. Eight years ago, the company Think TIM brought European technology to Mexico to carry out this task on a small scale at domestic level, or to treat water in small establishments such as hotels, businesses, or residential developments.​

​Last year, during the celebrations of the seventieth anniversary of diplomatic relations between Mexico and Switzerland, a privileged location was chosen for building La Casa de Suiza, a temporary thematic pavilion that hosted an ​exhibition about Switzerland's historical, cultural, and scientific heritage for the duration of two months. Louis-José Touron, the current Swiss Ambassador to Mexico, described the house as “a temporary and sustainable space that will enable the strengthening of bilateral links with Mexico, while at the same time opening spaces for Mexicans to learn a little more about our history, science, traditions, and gastronomy".

Something big is happening in UAE! And that is not only the buildings. A great deal of money is being invested in the infrastructure. And it is sustainability that counts. The Emirate intends to reduce the energy consumption of lamp posts by 30 % thanks to a new lighting system. The street lights are now manufactured and finished in a new factory. The German company C. ILLIES & Co opted for Leister welding tools for construction of the galvanization plant. An important reason for the collaboration was the guarantee by the local Leister partner, LLC, to provide a 24-hour service.

An ambitious company is forging ahead 
Laizhou, a small town near Qingdao – the city where the sailing competitions were held during the 2008 Summer Olympics – is currently undergoing an economic boom. This may be attributed in part to its favourable transport connections and to the unique media attention which it attracted in connection with the Games. Xin Li Composite Materials Co. Ltd has been among those companies to benefit from this unparalleled opportunity and has greatly extended its product range and sales area. It has transformed itself from a simple supplier of corrosion resistant containers to a complete provider of waste water treatment plants for the chemical, medical and metal industries. Xin Li now maintains a network of branches covering western China, including the far north.

Successful implementation of a business idea. 
Turkey is a sea-faring nation with a millennium of shipbuilding behind it. In a nondescript industrial building, typical of the more prosperous areas of Istanbul, innovative products have been created for the past five years: «Turbotsan » has been building boats made entirely from plastic. The original idea came to Burcin Yaslan, the owner of «Turbotsan», thanks to his exposure to inflatable Zodiac boats. He wanted his boat design to be sturdier than the German originals. The question, however, was which tools to use to weld the plastic and how could the critical weld quality be achieved? He who seeks shall find: Burcin Yaslan came across Tokgöz-Makina, and subsequently discovered the perfect tools for his application from Leister, which he could use to turn his dreams into reality. Leister sales partner for Turkey, Mahzar Tokgöz, carried out welding trials with Burcin Yaslan and introduced him to Leister’s innovative extrusion welding technology. Following this introduction to Leister, the first boat was successfully fabricated and floated.

From Switzerland to the Basque Country 
Thun, Switzerland, September 2006. In an otherwise empty industrial building, previously used by the Swiss army, big things are emerging: The company Colasit from the Berner Oberland region of Switzerland leased the building on a temporary basis. 25 mm thick polyethylene panels were prefabricated for their subsequent assembly in Spain. Three massive silos were built in the Basque Country, as commissioned by the German company «m+w Zander Gebäudetechnik GmbH»; these are now used in the biological washing process. They were integrated into a cellulose production plant. Using this technique, organic airborne pollutants are now extracted biologically in a multi-stage process. The waste gases flow through packed beds, are absorbed on the surface of substrate substances and are decomposed by microorganisms. The bio-washer results in a considerable reduction in odour and pollutant emissions. The population of Torrelavega and the surrounding region therefore waited eagerly for the plant to be commissioned.
