SME Project HAIRTILIZER INTRODUCTION Human hair is a material considered useless in most societies, perhaps due to public lack of knowledge, and therefore is found in the municipal waste streams in almost all cities and towns of the world. In rural areas or areas with low population density, the hair is thrown away in nature where it slowly decomposes over several years, eventually returning the constituent elements, namely, carbon, nitrogen, sulfur, and so forth, to their respective natural cycles. In urban areas or areas with high population density, it often accumulates in large amounts in the solid waste streams and chokes the drainage systems, posing a multifaceted problem. Due to slow degradation, it stays in the dumps/waste streams for long occupying large volumes of space. Over time, leachate from these dumps increases the nitrogen concentration in the water bodies, causing problems of eutrophication. Burning of human hair or the waste piles containing them—a practice observed in many parts of the world—produces foul odors and toxic gases such as ammonia, carbonyl sulfides, hydrogen sulfides, sulfur dioxide, phenols, nitriles, pyrroles, and pyridines. Open dumps of hair generate hair dust which causes discomfort to people near them and, if inhaled in large amounts, can result in several respiratory problems. Oils, sweat, and other organic matter sticking to the hair rot over time and become a source of foul odor and breeding ground for pathogens. The best way to address such problems is to develop systems which utilize the waste material as a resource. In addition to reducing waste, it contributes to the economy. As a potential material resource, human hair has the advantage that it is completely biodegradable, renewable, and available in every locality 1. ANALYZING THE PROBLEM a. Hair waste is a problem as society today experiences hair waste related problems such as Health and environmental Impact, space occupation, no value in hair waste is created so people don’t care to manage it and lack knowledge in hair waste management. b. Human and animal Hair waste can be put to good use by converting it to amino acid fertilizer which is a water-soluble fertilizer for plants. c. The major improvement will be a reduction in the cost of quality fertilizer, providing

hair waste re-use solution, making use of waste hair, promote the use of organic fertilizers which are more healthier for some crops’ growth as compared to chemical fertilizers d. This “pain” originates from: - The lack of awareness on waste management having the consequence of environmental uncleanliness, pollution on burning, foul odor and eutrophication. Pains: 1. Hair separation. The people are not used to separate this waste so they will need motivation to do it, as well as resources like: special bins/bags, near bins public stations. Furthermore, we will provide them with information about hair waste issues and ways to separate it.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
