The process developed by NTU Singapore involves pyrolysis, a high-temperature chemical process that breaks down plastic waste into hydrogen and carbon nanotubes. Here’s an elaboration of the process along with specific data points and informative facts:

1. Pyrolysis Technology: Pyrolysis is a thermal decomposition process that involves breaking down organic materials at high temperatures without the presence of oxygen. In the case of plastic waste, pyrolysis can convert it into useful products like hydrogen and carbon nanotubes.
2. Plastic Waste Feedstock: The plastic waste used in this process includes items that are difficult to recycle conventionally, such as contaminated food packaging, styrofoam, and plastic bags. These types of plastic litter are typically incinerated or sent to landfills, contributing to environmental pollution.
3. High Temperature Conversion: The plastic waste is subjected to high temperatures in a pyrolysis reactor, typically ranging from 300°C to 800°C. This heat causes the plastic molecules to break down into smaller hydrocarbon molecules, leading to the formation of gases like hydrogen and solid carbon residues.
4. Hydrogen Production: One of the main products of the pyrolysis process is hydrogen gas (H2). Hydrogen is separated from other gases produced during pyrolysis and can be collected for various applications. Hydrogen is a clean and versatile energy carrier that can be used for generating electricity and powering fuel cells.
5. Carbon Nanotube Formation: Along with hydrogen, the pyrolysis process also yields carbon nanotubes (CNTs). Carbon nanotubes are cylindrical carbon structures with remarkable mechanical, electrical, and thermal properties. They have applications in various fields, including biomedical and industrial sectors. CNTs can be separated and collected as a valuable by-product of the pyrolysis process.
6. Environmental Benefits: The conversion of plastic waste into hydrogen and carbon nanotubes through pyrolysis offers several environmental benefits. It helps mitigate the accumulation of plastic waste in landfills and reduces the need for incineration, which can release harmful pollutants into the environment. Additionally, the production of hydrogen as a clean energy source contributes to the transition towards a more sustainable and low-carbon economy.
7. Clean Energy Generation: Hydrogen produced from plastic waste via pyrolysis can be used as a clean fuel for various applications, including powering fuel cells in electric vehicles. When hydrogen is consumed in a fuel cell, the only by-product generated is clean water, making it an environmentally friendly energy source.
