Where can denim insulation be recycled?
Denim insulation can be recycled by taking it to the nearest recycling centres. Other options that could be availed include donation or composting.
Denim insulation is high-performance insulation which has become a rising insulation material as it has long-term impacts. Denim insulation consists of clipping, scraps and snipping of denim products which are released during product manufacturing. It may be made of recycled products
Denim insulation is mostly made from the scraps and clippings of denim clothing. It has a wide range of applications such as insulation and noise damping of ceilings, attics, and floors. Most denim insulations are class-A fire rated as well.
What is denim insulation?
Denim insulation is high-performance insulation which has become a rising insulation material as it has long-term impacts. Denim insulation consists of clipping, scraps and snipping of denim products which are released during product manufacturing. It may be made of recycled products.
Denim insulation is also referred to as “blue jeans insulation.” Denim is made of cotton which is a natural material, and it provides preferable and high-quality thermal efficiency. When jeans-made products are discarded in the environment it becomes raw material for insulation companies.
Blue jeans insulation provides insulation at home, workplaces et cetera as it provides good sound absorption. Such insulation is recyclable, for instance, if someone demolishes the walls of insulation, the discarded product can again be used as raw material for insulation purposes.
Furthermore, blue jeans insulation does not emit fumes or irritating pollutants that might cause difficulty in breathing or other respiratory allergies. As fibreglass insulation requires wool which emits irritants and causes allergies in humans. Denim insulation is an indoor-friendly product.
As denim is made up of natural products, it can be recycled many times when it is discarded. Such insulation does not produce any harmful product in the environment yet natural product i.e. cotton is not harvested at each time of insulation manufacturing.
What is denim insulation made of?
When denim products are discarded in the environment, the collection facilities collect them and send them to insulation manufacturing industries. Denim insulation manufacturing is a low-energy cost process. The products are treated at first by removing all extraneous materials including zippers, buttons, studs and fastening.
Then, jeans materials are transferred to the shredding stage where they are clipped and shredded into spinets. The material is ground further and converted into a required smaller size. Here mechanical grinders are used to get a smaller size of jeans.
Now the pieces are further torn down to bring jeans back to their raw form material which is cotton. Denim products are broken down into cotton fibres through processors which are used as raw material. The cotton fibres are collected in the form of bales and further sent for insulation manufacturing.
Here, collected bales are treated with borate flame retardants and anti-mould chemicals are applied to cotton fibre bales. Borate flame retardants are applied for cellulose insulation.
Borate flame retardants helped to reduce smoking, sparking and flame-reducing impacts on cellulose.
Borate flame retardants increase the durability of denim insulation as it makes char on the insulation which protects from fire spreading and electrical sparks from spreading ahead.
After borate flame retardants, the bales are shaped in the form of mats. The mats are cut down to required size and installed on the walls as insulators.
What are the applications of denim insulation? (5 applications)
One of the most common applications of denim insulation is in sound insulation walls. As denim insulation is made up of cotton that provides sound-proof qualities. Such insulation not only keeps residential or commercial buildings warm but also stops outdoor noise from entering the building.
Denim insulation has got recognition not only because it is easy to handle or low cost but due to its less irritating nature. Other insulation materials such as fibreglass release irritants and disturbs indoor air quality. Denim insulation is mainly used in homes.
Denim insulation is made of blue jeans which are converted into cotton fibres. This makes insulation easy to handle and easy to install at the domestic level. It does not require an installer to wear gloves, it can be touched barehanded.
Moreover, blue jeans insulation is 100% recyclable. The application is that such insulation does not cause natural resource depletion. The reason for blue jeans insulation recognition is that it can be handled and applied easily to home walls. Denim insulation is used in ceilings, flooring, walls, attic, and crawl spaces.
Instead of using high energy costs and high materials required for insulation, denim insulation is safe and easy to use. Many buildings and homes require insulation in ceilings, attics and crawl spaces which protects the inner environment from moisture and keeps home foundations long-lasting. Such insulation is mostly used in low temperate regions where homes must be kept warmer.
What is the environmental impact of denim insulation?
Denim insulation is a 100% post-consumer recycled product. Even if insulation is discarded, it can again be used by manufacturers to reconstruct insulation. Denim insulation is made in a low-carbon footprint process. Its manufacturing does not require high energy costs.
It has been reported that the recycling of old jeans has reduced an estimated 300 tons of waste from landfills. The manufacturers have diverted the way of old jeans from landfills to insulation industries. As its raw material is a post-consumer product, it makes It environmentally safe.
Furthermore, blue jeans insulation provides a healthy indoor air quality environment. it does not emit allergic materials which may cause irritation and difficulty in breathing. Such insulation is free from volatile organic carbons (VOCs) and other chemicals which may emit allergens to indoor air quality.
Old denim products have reduced their dumping rate in landfills which have caused an effective decrease in landfills in terms of waste. Such insulation is safe for health and provides safety.
As its manufacturing process involves a borate solution that provides class-A fire resistance properties which certify insulation against the spreading of fire and is readily flammable instead it inhibits fire spreading.
Denim insulation does not cause skin allergies as compared to other insulations. The downside of such insulation is that it requires a twice higher cost of installation as compared to fibreglass insulation. Denim insulation provides good thermal performance, it helps to decrease energy bills.
What are some alternatives to denim insulation?
There are some alternatives to denim insulation, but they are not as environmentally friendly as denim insulation. But if someone is looking for an alternative they can choose from wool insulation, wood fibre, hemp, jute and recycled glass bottle insulation.
These alternatives to blue jeans insulation require high energy costs during manufacturing and might release fumes and other allergic products that cause negative impacts on the environment.
As denim insulation is manufactured from 100% post-consumer material that’s why it is environmentally safe and a promising product.
Blue jeans insulation uses ecological renewable routes in manufacturing and processing as compared to other insulations such as mineral fibre insulation wrapped in foil which makes it difficult to handle. In terms of handling a product, denim insulation Is an easy and safer choice.
What is recycling?
Recycling can be defined as the reusing of consumer products by working on them. In this way, the products do not need to be made from scratch.
You may wonder what is the importance or significance of recycling. It can be summed up in the following key points:
- Better resource management
- Better waste management
- One of the best solutions to non-biodegradable waste
- Water conservation
- Decreased pressure on raw materials
- Decreased consumption of energy (which is mostly non-renewable)
- Increased labour and employment prospects
- Reduced pollution and environmental anomalies
Some of the common materials which can be recycled include:
- Paper
- Plastic
- Glass
- Metals
- Batteries
- Electronics
These are some examples. With the increasing awareness and better technology, more and more products are becoming recyclable which is a great indication of a shift towards sustainability and a green future.
The biggest advantage that is reaped by the process of recycling is that it is one of the best solutions to deal with non-biodegradable waste.
Non-biodegradable waste is a type of waste which may remain in the environment for hundreds of years. It can also cause environmental problems.
When non-biodegradable waste is recycled, these effects are delayed if not deterred. This saves our environment from a lot of degradative effects.
Another great benefit that is supported by the process of recycling is the re-usage of products. This decreases the stress given to raw materials.
We have already seen that natural textiles are sourced from natural sources such as plants or animals. Increased production of textiles from scratch will mean the unsustainable cutting of trees or the killing of animals.
The current scenario is already quite dense in this regard. It is estimated that humans have resulted in a decrease of more than 50% of the global tree count. In such dire scenarios, processes such as recycling offer great relief to the environment.
