As the world becomes aware of the environmental challenges posed by plastics, the construction industry is reducing its reliance on disposable plastics and increasing the use of recycled plastics. In the seventh issue of Construction Site Construction Magazine, we look at how the construction industry tackles environmental issues and helps countries reduce emissions and achieve better goals.
It takes up to 1000 years for plastics to degrade in soil, but the material's popularity is rapidly declining. Growing awareness of this impact on the environment has prompted companies and individuals to rethink their relationship with plastics.
As a major consumer of disposable plastics, the construction industry can help reduce waste by using less waste and recyclable materials. The most common plastics used in construction are polyvinyl chloride (PVC), high-density polyethylene (HDPE), and expanded polystyrene (EPS). Plastics are used for various applications such as seals, windows, doors, pipes, cables, floor coverings, and insulation.
The industry traditionally uses plastic films for packaging. When facilities and systems are in place to recycle, the packaging can be stored and incinerated at waste power plants. Not all plastics are damaged, and consumption is increasing in the industry; for example, plastic pipes are already responsible for many new pipe fittings.
In architecture, we are so busy creating something new that we often forget what happens at the end of a building's life cycle – inevitably collapsing. We want our buildings to be permanent and permanent, but sadly they are not, so where does all the garbage go?
With so much non-recyclable waste, it ends up in the ground, and as the land needed to fill it becomes increasingly scarce, we need to find an alternative solution. According to a Cardiff University study, the UK alone produces 70-105 million tonnes of waste annually, of which only 20% is biodegradable. With intelligent design and a sound understanding of biodegradable materials available in construction work, it is up to us as architects to make the right decisions throughout the life of the building.
Are bioplastics being used in commercial construction?
In recent years, bioplastic technology has been used to construct buildings, including constructing a modern Bioplastics Pavilion in Stuttgart, Germany. The free version was created as part of a joint project that brings together scientists, architects, production technicians, and environmentalists, resulting in a warming page with over 90% renewable resources covered. Named Arboblend, these materials are made from bioplastic pellets formed into sheets and can be further customized to achieve different surface properties and sizes.
Bioplastic granules mainly contain lignin, a rich natural substance, and a by-product of papermaking, which is responsible for the compressive strength of natural wood. Most lignin is currently burned for heat energy, but when combined with natural fibers such as cellulose, flax, and hemp, it causes the formation of arboreal bioplastic particles.
While Arbubland bioplastics have been used to manufacture furniture, garden tools, and even children's toys, it was first used as a building material. Its structure can be modified to produce different strength and rigidity characteristics and withstand combined pressure and compression loads like natural wood. Arboblend cladding sheet meets the high durability and flammability standards required for construction materials while reducing petroleum-based additives.
Research is also underway into bioplastics that will effectively isolate carbon and its use in areas traditionally in concrete, steel, and wood. Building large-scale infrastructure, such as bridges, booths, pipes, and water pipes, the use of bioplastics can significantly impact the world's carbon emissions and the production of commonly used petroleum-based construction products . during export. The amount of carbon dioxide can be reduced. And...Although this may be the early days of bioplastics as a building material, the Stuttgart pavilion and research present a promising future in their practical application.
Why are they being used?
Bioplastics can dispose of waste from petroleum-based plastic packaging and manufacture products with sustainable resources in non-perishable applications. This includes mobile phone cases, plastic tubes, and oil cables that are durable and flexible without the adverse environmental consequences of their traditional plastic counterparts.
Bioplastics are also important in the medical field. They are grown from polylactic acid that can dissolve in the body, so patients do not need a second operation to remove them. In agriculture, it can also be used in compostable mulch films made from starch polymers that do not require removal and refining in rural communities.
How are they being used?
Bioplastics can significantly reduce our dependence on fossil resources - which are more harmful to the environment than bioplastics. Therefore, it should come as no surprise that you can expect to see an increase in the production and use of bioplastics in the coming years.
Bioplastics are made from renewable sources such as corn oil, sugar beet, sugar, grass, and plants. The environmental damage caused by conventional plastics has been widely studied and disseminated. Bioplastics are made from renewable resources and biodegradable materials, which means that pollution has decreased significantly. Soon a full range of daily products will be produced using bioplastics. This includes things you might expect, such as product packaging and food services, as well as consumer electronics and automotive components.
What is the future for bioplastics in commercial construction?
Bioplastics are touted as the future material but are already being used smartly in the construction and design of homes. Bioplastics are now part of original designs that catch the eye and ensure that homes and city dwellers reduce carbon emissions from beautiful multi-colored surfaces to shaded buildings. In the family, they can be part of a sustainability strategy that extends to all aspects of life.
