There are three types of manure based on solid content: cattle manure with 11-13% solids, manure with 3-10% solids, and manure with 3% or less solids. Traditionally, cattle manure was used as fertilizer but other liquid manures were wasted, polluting waterways. Now, anaerobic digestion is used to process manure which produces biogas for energy and waste that can be used as fertilizer or cattle bedding, reducing environmental impact but digesters are very expensive to install.

solid waste management
This document discusses human waste and waste conservation. It describes different types of solid waste including municipal, industrial, biomedical, and e-waste. Approximately 26.7% of household waste comes from toilets. The document then discusses bio-toilets, which are eco-friendly alternatives that convert human waste into biogas and liquid that can be used for watering plants. Bio-toilets are easy to operate and maintain, produce no smell, and generate biogas that can be used as an energy source. Their implementation can help avoid pollution and keep public places safer.
Wastewater as a Resource, by Dr. Seneshaw Tsegaye
This document discusses the potential for harvesting resources from wastewater in sub-Saharan Africa. It notes that sanitation coverage is below 50% in many countries and wastewater is often seen as a burden. However, wastewater can be viewed as a resource from which nutrients like nitrogen and phosphorus can be recovered and reused as fertilizers. Examples are given of entrepreneurs developing businesses to recover nutrients from wastewater for use in agriculture. The document argues that we need new perspectives that focus on beneficiation and maximizing the value obtained from wastewater rather than just treatment.

LIVESTOCK WASTE DISPOSAL AND MANAGEMENT
Livestock waste can be disposed of and utilized in several ways. It includes liquid waste like urine and wash water as well as solid waste like feces and bedding. Livestock waste can be applied directly to crop land as fertilizer, used to feed animals, or processed to produce energy and biogas. Common waste disposal systems include combining liquid and solid waste to apply to fields, separating wastes with solids stored in pole or pit structures, and treating waste in lagoons for microbial breakdown. Livestock waste is also used in biogas plants to produce methane gas for cooking and electricity generation.
