Fabric made from coffee grounds

Nowadays, our lives have been transformed dramatically thanks to advanced technology. Along with positive effects, there are also numerous significant environmental problems, especially in the fashion industry. Under this circumstance, our group wants to introduce recycled coffee grounds fabric as a practical and effective solution to address this issue.
The idea of coffee-ground fabric accidentally came to Jason Chen’s mind when his wife humorously told people to take coffee grounds home to deodorize odors. After 4 years of experiment, the first fabric made from coffee grounds was created, named S.Café.
Every day, we saw adults drink and discard coffee grounds which led to wonders about whether this waste had any detrimental effect on the environment. Therefore, we decided to research and were impressed by the idea of manufacturing them into fabric.
According to the UN, the fashion industry is the second largest polluter on the planet. According to Business Insider, 85% of all textiles end up in landfills every year. Washing clothes alone releases 500,000 tons of microfibres into the ocean each year, equivalent to 50 billion plastic bottles. Meanwhile, Vietnam is a major coffee producer with over 500,000 coffee shops ranging from small businesses to big chains. Hence, we have access to enormous amounts of coffee grounds. With dedicated efforts, these used grounds can be efficiently collected for sustainable uses.
Coffee yarn is made from a several-step process. First, coffee grounds are cleaned and their oil is extracted. Under high-pressure, low-temperature conditions, the grounds are combined with polymer to create a spinning solution. This solution is then transformed into fibers, yarn, and ultimately, clothes.
Coffee ground fabric offers several advantages for the environment, consumers, and businesses. Environmental-wise, this fabric is very sustainable. The process of making this fabric is extremely energy efficient, as it requires only 160 Celcius degrees to turn coffee grounds into yarn, compared to 600 Celcius degrees for other materials. Since this textile is made from abundant organic material and requires few harmful chemicals, the resulting fabric is biodegradable. Furthermore, the fabric provides odor control and protection from UV rays, therefore reducing the amount of chemicals needed to be used for treatment. From consumers’ perspectives, the fabric provides ultimate comfort as it is highly resistant to mold and odor. Additionally, this fabric is naturally UV-resistant because coffee grounds have antioxidant compounds, thick structures and are tightly woven. For businesses, not only is the main material readily available and inexpensive, but the business can also enhance their own reputation due to the high-quality products with environmental and social responsibility.
In conclusion, coffee ground fabric is an effective resolution to mitigate the impact of the fashion industry and make use of plentiful coffee resources. As Vivienne Westwood wisely stated: "Buy less. Choose well. Make it last." We should inspire our communities for a greener and more responsible future.

Organize Information Logically:
- Detailed explanation: The essay presents a clear progression of ideas, starting from the introduction of the problem in the fashion industry to the solution of coffee ground fabric. Each paragraph builds on the previous one, effectively guiding the reader through the argument. For example, the transition from discussing the environmental impact of the fashion industry to the introduction of coffee ground fabric is smooth and logical. However, some sections could benefit from clearer topic sentences to signal the main idea of each paragraph.
- How to improve: To enhance logical flow, consider using more explicit topic sentences that outline the main point of each paragraph. This will help the reader follow the argument more easily. Additionally, ensure that each paragraph transitions smoothly into the next by using linking phrases or sentences that connect ideas.
Use Paragraphs:
- Detailed explanation: The essay is divided into distinct paragraphs, each addressing a specific aspect of the topic. However, some paragraphs, such as the one detailing the advantages of coffee ground fabric, are quite lengthy and could be broken down into smaller, more focused paragraphs. This would improve readability and allow for a more in-depth exploration of each advantage.
- How to improve: Aim to create more balanced paragraphs by dividing longer ones into smaller sections that focus on a single idea. For instance, consider separating the environmental benefits from the consumer and business perspectives into distinct paragraphs. This will enhance clarity and allow for a more organized presentation of information.
Use a Range of Cohesive Devices:
- Detailed explanation: The essay demonstrates a good use of cohesive devices, such as "therefore," "meanwhile," and "furthermore," which help to connect ideas and maintain the flow of information.

Band điểm Lexical Resource ước lượng: 7

Band Score for Lexical Resource: 7

Use a Wide Range of Vocabulary:
- Detailed explanation: The essay demonstrates a good range of vocabulary relevant to the topic of sustainable fashion and environmental issues. Terms like "recycled," "biodegradable," "sustainable," and "microfibres" are used appropriately, showcasing an understanding of the subject matter. However, there are instances where more varied synonyms could enhance the richness of the language. For example, the repeated use of "fabric" could be diversified with terms like "textile" or "material."
- How to improve: To elevate the lexical resource, consider incorporating more synonyms and related terms. For instance, instead of repeatedly using "fabric," you could use "textile" or "material" in various contexts. Additionally, introducing more descriptive adjectives or adverbs could provide depth to your arguments, such as "innovative," "eco-friendly," or "cost-effective."
Use Vocabulary Precisely:
- Detailed explanation: The essay generally uses vocabulary accurately, but there are moments of imprecision. For example, the phrase "environmental-wise" is somewhat awkward and less common; a more precise term like "from an environmental perspective" would be clearer. Additionally, the phrase "ultimate comfort" could be better expressed as "exceptional comfort" to convey a stronger meaning.
- How to improve: Focus on refining word choices for clarity and precision. When expressing ideas, consider the context and choose words that best convey your intended meaning. For example, replace "environmental-wise" with "from an environmental standpoint" to enhance clarity. Regularly consult a thesaurus to explore alternatives that may fit better in context.

For instance, complex sentences such as "According to the UN, the fashion industry is the second largest polluter on the planet" effectively convey detailed information. Additionally, the use of conditional structures, as seen in "if the main material is readily available and inexpensive," showcases an understanding of nuanced grammatical forms. However, there are instances of simpler sentence constructions that could be enhanced, such as "Every day, we saw adults drink and discard coffee grounds," which could be rephrased for greater complexity.
- How to improve: To diversify sentence structures further, consider incorporating more compound-complex sentences and varying the placement of clauses. For example, instead of "the fabric provides ultimate comfort as it is highly resistant to mold and odor," you could rephrase it to "Highly resistant to mold and odor, the fabric provides ultimate comfort to consumers." This not only adds variety but also emphasizes important information.
Use Grammar and Punctuation Accurately:
- Detailed explanation: The essay generally exhibits strong grammatical accuracy, with few errors. For example, the phrase "the process of making this fabric is extremely energy efficient" is grammatically sound. However, there are minor punctuation issues, such as the lack of a comma in "under high-pressure, low-temperature conditions," which could lead to confusion. Additionally, the phrase "160 Celcius degrees" should be corrected to "160 degrees Celsius" for proper formatting.
- How to improve: To enhance grammatical accuracy, pay attention to punctuation, especially in complex sentences. Regularly review common punctuation rules, such as comma usage in lists and after introductory clauses. Furthermore, ensure that terms are correctly formatted, such as "Celsius," to maintain professionalism in writing. Proofreading for these details can significantly elevate the overall quality of the essay.
