Renewable resources can provide a steady supply of clean energy and are energy sources that are never depleted and Clean energy is produced by renewable resources, which means reduced pollution and greenhouse gas emissions, both of which contribute to climate change. Biomass energy (such as ethanol), geothermal power, hydropower, wind energy, and solar energy are examples of renewable resources.
Biopolymers are biodegradable polymers that are made from bio-based resources. Molecular biotechnology is used to create these bio-polymers, which use bacteria as factories to synthesise huge and complicated chemicals. Bioresources used in the form of fresh and waste biomass is both an opportunity and a challenge for the future, as it provides the opportunity to replace fossil fuels in the manufacture of energy carriers, materials, and specialty chemicals while are also reducing market pressure in a carbon-neutral manner.
