What is a creative alternative use for coffee grounds in a cafe?

Using coffee grounds as a natural fertilizer for plants is an excellent alternative use in a café setting. Coffee grounds are rich in nitrogen, which is a vital nutrient for plant growth. They can be added to compost or mixed into the soil to enhance its nutrient content. This not only provides a sustainable way to recycle waste but also helps promote healthy plant growth, making it an environmentally friendly choice for cafés that want to minimize their ecological footprint.

Additionally, this practice can resonate with customers who appreciate eco-friendly initiatives, potentially enhancing the café's image and customer loyalty. The other options, while also viable alternative uses, do not align as closely with the direct benefits seen from using coffee grounds as fertilizer. For instance, while coffee grounds can indeed repel insects and contribute to natural dyes, the use as fertilizer offers a more significant agricultural benefit by enhancing the growth of plants.
