Your choices can reduce the environmental impact!
Today we know more about the things that negatively and positively affect our environment. Around the world, scientific work is being carried out to find facts upon which we can base changes and decisions. For many people it can be difficult to absorb this information, and it is not always easily accessible.
It can therefore be difficult to evaluate and make decisions regarding which methods and products give particular results. In this section we try to help you to easily understand what generates more or less emissions in our industry. Read more in the menu on the right.
Inpipe’s liners consist of a composite of polyester and fibreglass enclosed in two plastic foils. The plastic consists both of polyester resin but also of foils manufactured from PP, PE and PU.
Environmental impact from plastic composites
Plastic is usually a petroleum product. In other words, it is manufactured from oil. Plastic has a number of advantages. It allows us to make products and solutions that produce higher energy efficiency than if other materials were used.
Plastic can be reinforced or in other ways given a high resistance, which means that many plastic products contribute to reduced material use and lower weight in finished products.
According to one study, due to their energy efficiency in production, effective production processes and reduction of material use, plastics contribute to a reduction of oil consumption corresponding to 50 million tonnes of crude oil per year, corresponding to permanently removing around 49 million cars from circulation. Plastic use today represents around 4% of the global use of fossil fuels. According to the study, an increase of the use of plastics could contribute to further reducing emissions of greenhouse gases due to their characteristics during manufacture and in the end product.

This can be compared with the manufacture of cement, which is a component of concrete and represents 5% of global emissions. (Source: http://www.economist.com/node/10329254) To then manufacture concrete requires additional material in the form of crushed gravel or similar substances together with transport of heavy material. Nor is there any reliable data that shows the quantity of emissions generated by concrete manufacture.
All manufacturing generates emissions during different phases of the process, which includes the manufacture of composite material. Depending on the content of the composite, the emissions will vary in size, but due to their life expectancies and low weight compared with other materials, emissions are reduced when a lifecycle analysis is carried out.

One metre of concrete pipe of inner diameter 225 mm weighs approximately 120 kg/m; the corresponding pipe for relining weighs approximately 5 kg/m. It is therefore clear that emissions from transport and handling are higher for the concrete pipe.
