The Use of Recyclable Thermoset to cut landfill Waste

The Use of Recyclable Thermoset to cut landfill Waste

Philippines are a flood prone country, and one of the reasons is lots and lots of plastics in the garbage. We are a populated country so the higher the population the higher the demand of needs.

Plastics are non-biodegradable. It took thousands of years before it completely destroyed and broken down into very small parts by natural processes, bacteria, etc. Plastics are usually the reasons of floods because it clogs the drainage that stops the water flowing in the canal that can cause a flood. Due to the durability of the plastics it is now the vital part of our modern world, every move we make we are using it, like for example we are using plastics in the grocery store because paper bag alone cannot carry out the heaviness of our groceries; our garbage bag itself is a plastic, mobile phones and circuit boards to the aerospace industry.

Plastics are divided into thermoplastics and thermoset plastics.  Thermoplastics are generally recyclable, so it can be heated and reshaped many times, it can be seen everywhere. This one is thin and soft plastics like our plastic cups, plastic bottles, etc. So even at home, we can make our own shape of thermo plastics through heating it and form of what shape we want. However thermoset plastics can only heated and shaped once, after which molecular changes mean they are cured, retaining their shape and strength even when subject to intense heat and pressure, so these kind of plastic is hard and it capable to lasts longer like thousands of years. We can commonly use this as drawer, plates, comb and other basic equipment’s inside the house.

 

In 2014, publication of a landmark paper in Science announcing discovery of new classes of the thermosetting polymers that are recyclable which is the Poly (hexahydrotriazine)s, or PHT’s. It dissolved in the strong acid and breaking apart the polymer chains into component monomers that can then be reassembled into new products.

Like unrecyclable thermosets, this is also rigid, easily melt and tough, with the same potential applications as their unrecyclable forerunners. This innovation – if widely deployed – can speed up the move of circular economy, and with a big reduction of plastics landfill wastes even though no recycling is 100 percent efficient.

In order for us to reduce landfill wastes we can recycle our used materials. Plastic bottle is one of the examples. After drinking we can use it as a vase in our home through decorating it and make it more attractive, we can also use it as a pot for our plant, etc.

Garbage is everywhere and we can use them if we are using our creativity in recycling. Since plastic is biodegradable and lasts longer than our lives we can use them in daily living not just to reduce wastes but also to make our environment clean.
