RESOURCE SAVING SOLUTIONS FOR THE SHARED USE OF HOUSEHOLD WASTE REMOVAL SYSTEMSAND SEWAGE NETWORKS IN MODERN RESIDENTIAL BUILDINGS
Страницы 132-138
The problem of resource saving is particularly relevant for household waste removal systems and sewage networks in modern residential houses. Some options for the shared use of sewage networks and natural organic waste removal systems in residential buildings are assessed by the author. Layouts, operation patterns and elements of the systems are provided. Strengths of shared operation of the systems and networks are analyzed with account for the present-day requirements applicable to the systems in question. The positive factor is that residents do not need to spend money for expensive food waste disposers for their homes. They will also use garbage chutes in their houses.Joint operation of food waste removal systems and domestic sewage networks will reduce the load on landfills which has been increasing in the recent years. It will increase the load on urban sewage networks and water treatment facilities, but it will not be a critical factor, because treatment facilities are capable of purifying water without much difficulty. Processed food waste may be applied to produce fertilizers and biogas to be used as fuel. Therefore, benefits of the limited use of landfills are obvious.Waste shredding is the most convenient, efficient and nature friendly way of processing the organic waste at the initial stage of its generation. It prevents rotting typical for the organic waste if disposed together with the municipal solid waste.The experience of the United States, where food waste is treated by in-sink food erators and removed into the sewage system is less expensive for city budgets than their disposal at landfills.Food wastes consist mainly of the water (70 %); therefore, water treatment facilities assure a more natural way of processing this type of waste than waste collection and disposal. Separation of organic waste from solid waste also reduces the number of disease vectors such as flies, rodents, and cockroaches.
