Sustainable business model: transforming goat manure waste combined with egg shells into economical and environmentally friendly products

The large number of people who keep goats in their residential areas has caused the accumulation of goat waste in Cangkring Village, Bantul, Yogyakarta. This often occurs due to a lack of understanding of effective waste management. On the other hand, eggshell waste from production activities in home industries such as cake shops in Bantul also causes similar problems. This study aims to identify an effective integrated management method for utilizing goat waste and egg shells to produce valuable products, such as organic manure enriched with calcium and nutrients for plants. With a circular economy approach, this study involved field observations and interviews with residents in Cangkring Village, Bambanglipuro, Bantul, and several cakes shop entrepreneurs in Bantul Regency. The results of this study indicate that processing goat manure and eggshell waste can significantly reduce waste volume while providing added value for the public through more efficient and high-value fertilizer production and helping to open up new business opportunities that can support the local economy. This study provides an important contribution to sustainable organic waste management; it not only emphasizes waste reduction but also transforms wasted resources into solutions that benefit the ecosystem in local communities.
