Plastic formwork since its discovery has become one of the popular choices in the Indian construction sector. With rapid urbanization, finding a solution that was environmentally friendly and sustainable was essential.

Although traditional formwork like wood and aluminum have significant environmental impacts, they too have adverse effects. Making wood/timber formwork requires wood which leads to an increase in deforestation. While metal/aluminum formwork consumes extensive energy to make.

As for why ‘Plastic formwork in construction’ is beneficial:- they are made from recycled materials. Using the used material reduces the waste and also reduces energy consumption. Reusing plastics that would end up in landfills will help in reducing the potential land pollution. Additionally, plastic formworks could be reused multiple times as they are more durable and lightweight.
What are plastic formworks? What are they made up of?

Plastic formwork acts like a temporary mold that is used to shape the wet concrete. They are mostly made using polypropylene or polyethylene. Because of polypropylene and polyethylene, they have the ability to resist moisture and provide durability.

To make plastic formwork, small pieces of plastic are prepared first. These small pieces are generally made up of polypropylene, polyethylene, or recycled plastic. These plastic pellets are later melted into the liquid.

Later they are poured into a special formwork mold to cool down. These formwork molds also help plastic pellets to take shape and harden. Once set the hardened plastic formwork is removed from the mold and undergoes a finishing process.

After ensuring the quality of the formwork they are dispatched to sell. This process ensures plastic formworks are durable, lightweight, and easy to handle.
Plastic formwork advantages and disadvantages
Compared to traditional formwork they can reduce the waste that is generated by using wood or metal formwork. They could also be cleaned easily. However, there are some drawbacks that you should also consider.

Advantages of Using Plastic Formwork India

Plastic formworks offer benefits in terms of durability, longevity, and reusability. Some of the below-mentioned advantages make plastic formworks a valuable choice.

1)Plastic formworks are known for their durability.

Because of the material (polypropylene, polyethylene, or recycled plastic) used in making plastic formwork, they are designed to withstand repeated use without wear and tear. Unlike certain formwork materials like wood which couldn't be reused again after a certain time.

2)Plastic formworks are light in weight.

In comparison with wood or metal, plastic formworks are lightweight and can be easily handled or carried anywhere. Because of their weightlessness, they don't need special equipment to install. This also reduces the physical strain on workers which they normally go through while dealing with traditional materials like wood.

3)Plastic formworks are known for reusability.

Plastic formworks can be reused multiple times. This minimizes the cost and requirements for purchasing new formwork again and again. Due to their longevity, it makes them very cost-effective and budget-friendly. Plastic formworks are suitable for long-term projects where reusability is an essential component.

*4)Plastic formwork requires low maintenance. *

Plastic formwork only requires minimal maintenance after usage. They can just be cleaned using water. The best part about plastic formwork is they are highly resistant to moisture. They would not rot or decay if exposed to water. They are suitable to be used in coastal projects or during the rainy season.

*5)Plastic formworks have a smooth finish. *

The wet concrete is not damaged during the molding process which provides a smooth and precise finishing. As a result, it lessens the need for additional work for a smooth finish. Plastic formworks are the best choice for high-end residential projects where smooth finishing is essential.

6)Plastic formworks are quick to assemble and disassemble.

Plastic formworks are designed for easy assembling and disassembling. Because of their lightness, it makes it easier for workers to put the plastic formwork together and dismantle it quickly without wasting time. This also accelerates the construction process.
Disadvantages of Using Plastic Formwork India
While plastic formwork offers various advantages there are certain disadvantages you need to know. Here are some of the disadvantages of plastic formwork.

*1)Plastic formwork has a high initial cost. *

Although plastic formwork is cost-effective in the long run they have a higher initial cost compared to other materials like wood or metal. This high purchasing cost would not make it suitable for small-scale businesses having small or lower budgets.

*2)Plastic formwork has limited loading capacity. *

Even if plastic formwork is durable, it is still not suitable for very heavy or high-load applications. Plastic formworks may not be the best option to work with projects like bridges or high-rise buildings.

*3)Plastic formworks are sensitive to temperature. *

Plastic formwork is sensitive to temperature. They might become brittle or lose under hot and cold temperatures. This may affect the overall performance and structural integrity. Under intense weather like in Rajasthan, plastic formwork may end up being deformed or loose.

4)Plastic formworks are not available everywhere.

Plastic formwork has limited availability. One of the reasons behind this is they are made from recycled plastic and it requires special equipment to convert them into plastic formwork. And also there is a limited number of suppliers who sell plastic formwork. This is the reason why plastic formwork is not easily available.

*5)Plastic formwork’s durability is in question. *

Plastic formwork may crack or break under certain conditions which could impact its durability. Unlike metal which could withstand harsh conditions, there are high chance plastic formwork wouldn't have a chance to survive extreme conditions.

Environmental Benefits of Plastic Formwork: What are the Environment benefits of using plastic formworks?

The use of plastic formwork has affected the environment in a very positive way. It has emerged as an effective solution for reducing stacking waste. Here are some of the environmental benefits that plastic formworks have curbed.

1)Reduction in waste: As plastic formworks are reusable this helps in reducing construction waste. Plastic formwork can be used multiple times before they are recycled again.
2)Reduced deforestation: Because of the use of plastic formwork instead of traditional formwork (Timber) the demand for wood has decreased with it. This has somehow slowed down the growing deforestation movement happening in past decades.
3)Lower carbon footprint: The production and use of plastic formwork have resulted in a lower carbon footprint. Compared to other materials plastic formwork is lightweight and doesn't need any special transportation, this in turn reduces carbon emissions.
4)Energy efficiency: To manufacture plastic formwork requires less energy and transport in comparison to traditional materials. At the same time, there is no use of chemicals to make them.
5)Cleaning without chemicals: Cleaning Plastic formwork is very easy and simple. After using plastic formwork you just have to rinse it off with soap water. There is no need to use chemical cleaning agents which are harmful to the environment.
6)Minimize resource consumption and waste: In contrast to traditional formworks, plastic formworks are highly durable. Because of this it also reduces the frequency of replacements. Furthermore, it minimizes the resources used for making.

By using plastic formworks the construction sector could contribute to the environment and achieve sustainability.

Final Points to Note

Plastic formwork has transformed the construction industry. It has become a sustainable and environmentally friendly alternative to traditional materials. With the increasing construction waste using plastic formwork has become essential for the environment.

One of the primary advantages of using plastic formwork is its noticeable contribution towards reducing waste. It minimizes the construction waste and reduces the need for new formwork. Additionally, the use of recycled plastics in formwork promotes recycling. It also reduces carbon emissions and carbon footprint.
