Ramie Soap Saver Pouch

1. Material Composition and Durability

• Natural and Biodegradable Materials: Soap Saver Pouches are often made from natural materials like sisal or cotton, which are biodegradable. These materials break down more easily in the environment compared to synthetic alternatives, reducing long-term waste.
• Durability: Natural fiber pouches are durable and can be reused multiple times, reducing the need for frequent replacements. This longevity means fewer resources are used over time, contributing to lower overall environmental impact.

2. Reduction in Soap Waste

• Maximizing Soap Usage: The pouch allows users to use up soap remnants that would otherwise be discarded. This efficient use of soap reduces overall consumption and waste, which in turn lowers the demand for soap production.
• Less Packaging Waste: By extending the life of soap bars, the need for new soap bars (and their packaging) is reduced. This means less plastic and other packaging materials are produced, which contributes to lower carbon emissions.

3. Energy and Water Savings

• Efficient Lathering: Soap Saver Pouches help create a rich lather quickly, requiring less water and soap to achieve the same level of cleanliness. This efficiency can lead to reduced water and energy usage during showers or baths.

4. Lifecycle Assessment

• Lower Production Emissions: The production of natural fiber materials like sisal has a lower carbon footprint compared to synthetic materials. Sisal, for example, is grown with minimal pesticide and fertilizer use, which reduces the carbon emissions associated with its cultivation and processing .
• End-of-Life Impact: Natural fiber pouches decompose naturally, whereas synthetic materials can persist in the environment for hundreds of years, contributing to pollution and greenhouse gas emissions as they break down.

5. Supporting Local and Sustainable Practices

• Sustainable Farming: Sisal and cotton are often grown in regions where sustainable farming practices are encouraged, which can include crop rotation, organic farming, and reduced use of harmful chemicals .
• Fair Trade and Ethical Production: Many Soap Saver Pouches are produced by small-scale farmers and artisans under fair trade conditions, ensuring that the production process supports sustainable economic development.

1. Raw Material Production

Assuming the Soap Saver Pouch is made from sisal:

• Sisal Production:
  • Carbon footprint of sisal: approximately 0.72 kg CO₂e per kg of sisal .
  • Average weight of a Soap Saver Pouch: around 30 grams (0.03 kg).

$\text{Carbon footprint for raw material}=0.72\text{kg CO₂e/kg}\times 0.03\text{kg}=0.0216\text{kg CO₂e}$

2. Manufacturing Process

The manufacturing process includes energy used in weaving, stitching, and packaging:

• Energy Consumption:
  • Estimated energy usage for production: 0.1 kWh per pouch.
  • Carbon footprint of electricity: varies by region, but let's assume an average of 0.5 kg CO₂e per kWh.

$\text{Carbon footprint for manufacturing}=0.1\text{kWh}\times 0.5\text{kg CO₂e/kWh}=0.05\text{kg CO₂e}$

3. Transportation

Assuming transportation from the manufacturing site to the consumer involves a combination of road and sea transport:

• Distance Traveled:
  • Let's assume an average distance of 10,000 km (from production site to consumer).
  • Average carbon footprint for combined road and sea transport: 0.02 kg CO₂e per ton-kilometer.

$\text{Weight of 1 pouch}=0.03\text{kg}$ $\text{Carbon footprint for transportation}=0.03\text{kg}\times 10,000\text{km}\times 0.02\text{kg CO₂e/ton-km}=0.006\text{kg CO₂e}$

4. Usage

Considering the usage phase, the carbon footprint is negligible compared to production and transportation.

5. Disposal

Since the pouch is biodegradable, its end-of-life impact is minimal:

• Decomposition Emissions: Natural decomposition of sisal has negligible CO₂e emissions.

Total Carbon Footprint

Summing up the different components: $\text{Total Carbon Footprint}=0.0216\text{kg CO₂e (raw material)}+0.05\text{kg CO₂e (manufacturing)}+0.006\text{kg CO₂e (transportation)}$ $\text{Total Carbon Footprint}=0.0776\text{kg CO₂e}$ So, the estimated carbon footprint of a single Soap Saver Pouch is approximately 0.078 kg CO₂e.

Scientific References

1. Material Production: Sisal cultivation has a relatively low environmental impact. A study on the life cycle assessment of sisal indicates that its production has lower greenhouse gas emissions compared to synthetic fibers (Habasit, "Environmental impacts of sisal production", 2017).
2. Biodegradability and Compostability: Natural fibers like sisal and cotton are known to decompose within months under composting conditions, significantly reducing their environmental footprint compared to plastics (Levine, L.
