Question 18
Assess the impact of the recent development of a named biopolymer on society and the environment.
Worked Solution & Example Answer:Assess the impact of the recent development of a named biopolymer on society and the environment. - HSC - SSCE Chemistry - Question 18 - 2005 - Paper 1
Step 1
Evaluate the impact of a named biopolymer on society
Answer
The development of polylactic acid (PLA), a common biopolymer, has significantly impacted society. As a biodegradable alternative to traditional plastics, PLA helps reduce plastic waste. Its use in various applications like packaging and disposable cutlery promotes environmental sustainability, raising awareness about eco-friendly materials. Furthermore, the shift towards biopolymers encourages industries to adopt greener practices, which can improve brand image and customer loyalty.
Step 2
Evaluate the impact of a named biopolymer on the environment
Answer
On an environmental level, the production and degradation of PLA significantly lower greenhouse gas emissions compared to conventional plastics. Being derived from renewable resources such as corn starch, PLA production reduces dependence on fossil fuels. However, it's essential to manage agricultural practices for corn to avoid negative effects like soil depletion and nutrient runoff. Overall, the environmental benefits of PLA highlight the potential of biopolymers in combating pollution and fostering sustainable practices.
