Question
Greenfeet publishes a sustainability progress report every year which summarizes the total environmental impact of the products it produces, see Figure 1.
In 2018, Greenfeet launched the Vertue shoe with an upper made entirely from plastic recovered from the ocean, see Figure 2. In 2019, Greenfeet expected to make 1.5 million pairs of Vertue shoes from 200 tons of recovered plastic, using approximately 13 bottles per shoe.
In 2019 Greenfeet updated its original Climeate shoe shown in Figure 3, with yarns made from recycled plastic waste collected from beaches. The updated shoe is shown in Figure 4.
Greenfeet has a strategic goal to reduce water use and water pollution. State the percentage of pollution caused by water pollution.
List two consequences of a manufacturing process that uses large quantities of raw materials.
Outline how the Greenfeet Vertue shoe is an example of waste mitigation.
Outline one driver for cleaning up manufacturing.
Outline why sketches would be used in the development of the Greenfeet Vertue shoe.
Explain one physiological factor considered in shoe sole design.
List one characteristic that the retro-styled Greenfeet Climeate shoe (2019) shares with the original Greenfeet Climeate shoe (2004).
Outline the maximum and minimum percentiles that Greenfeet would use when manufacturing the Climeate shoe.
Describe how the EVA rubber sole of the Greenfeet Climeate shoe could be moulded.
Discuss whether the Greenfeet Climeate shoe (2019) balances the compromise between form and function.

Examiners report
Very straightforward
Good range of answers provided
Quite straightforward, well answered. Most candidates achieved at least one mark.
Many candidates believed consumer pressure was a driver for cleaning up manufacturing, however it is more a driver for green design (see topics 2.4 & 2.5).
A fair question but not well answered. Very few candidates achieved full marks for this question. Although two clusters were provided in the markscheme, many candidate's answers crossed clusters or missed the point in general.
Most candidates answered from the first cluster, mentioning comfort and some were able to gain a second mark, but not many achieved a third mark from either cluster option. This may have been better as a 2 mark question but was a good discriminator.
A very easy question, well answered. Most candidates opted for the EVA rubber sole (from the stimulus material) or three diagonal stripes.
A reasonably straightforward question with most candidates able to identify the percentile range and good number being awarded two marks.
A difficult question with very few correct responses. The answers most commonly seen from candidates referred to injection moulding. Many also spoke of a liquid rubber being poured into a mould. Very few went for the most apparent correct method of compression moulding.
A very easy question regarding form and function that has proved challenging in the past. The mark scheme allowed for any combination of form/function balance or non-balance meaning almost all students were able to achieve at least one mark. The question was a good discriminator though as achieving 3 marks was more challenging in any form of the argument. Arguing for a balanced compromise provided better opportunities for higher marks.
