Dry and Wet Waste Segregation and Management System
European Journal of Engineering and Technology Research
Waste management faces numerous difficulties because of its enormous, quickly developing populace in a densely populated nation in the developing nations. The primary target of the research work is dry and wet waste separation and management process. A portion of the trash individuals produce is biodegradable, some are recyclable, and some are not one or the other. Waste segregation includes isolating wastes as per how it's dealt with or handled. Isolation of waste through at unloading locales burns-through additional time and labor. This work suggests a Spontaneous Waste Segregator (SWS) which is a modest, simple to utilize answer for an isolation framework at family units. The AWS utilizes a dampness sensor to distinguish wet and dry waste and separate them with ultrasound sensors for ceaseless checking and GSM based waste level notice to authority. This system can be used in industries for the employees to use daily. It will be used for wet food junks or even as a normal dail...
Municipal waste management systems for domestic use
Energy, 2017
Every year, the average citizen of a developed country produces about half a tonne of waste, thus waste management is an essential industry. Old waste management systems based on the collection of mixed/ sorted waste and transporting it a long way to disposal sites has a significant negative impact on the environment and humans. This paper will review the available waste management systems for households. Biological methods (such as composting or anaerobic digestion) and physicochemical methods (such as burning or pyrolysis) of waste utilization will be considered from the householder's point of view. The most important features of each system will be discussed and compared. Municipal waste management systems for domestic use could eliminate or significantly reduce the stage of waste collection and transportation. Additionally, they should not require special infrastructure and at the same time should allow garbage to be changed into safe products or energy sources with no harmful emissions. The aim of the work is to identify the best available waste disposal systems for domestic use.
This reseach paper would not have been possible without the guidance and the help of several individuals who contributed and extended their valuable assistance in the preparation and completion of this research.
Blue Diversion: a new approach to sanitation in informal settlements
Journal of Water, Sanitation and Hygiene for Development, 2014
The sanitation concept ‘Blue Diversion’ (www.bluediversiontoilet.com) was developed as a possible answer to the sanitation crisis in urban slums. It is based on two main elements: (1) diversion of urine, feces, and water at the source as the basis for efficient resource recovery, and (2) linking different scales (family toilets and semi-centralized resource recovery). Our objective was to develop an attractive ‘grid-free’ (i.e. functioning without piped water, sewer, and electrical grid) dry urine-diverting toilet, which provides water (through recycling on-site) for flushing, personal hygiene (anal cleansing and menstrual hygiene), and hand washing. This service, including the entire sanitation value chain, should eventually be made available as a profitable business with total user fees of 5 ¢/p/d. The results presented in this paper are (1) a toilet design model, (2) the development of a new type of membrane bioreactor for treating flush and wash water, (3) main results of a geog...

Linkage to the Eawag Compendium of Sanitation Systems and Technologies This document is designed as a supplement to the Eawag Compendium of Sanitation Systems and Technologies 1 , which from here on out will be referred to as the Eawag Compendium. The Eawag Compendium highlights different technologies along the sanitation service chain in five functional groups: the User Interface (toilet), On-Site Storage and Treatment, Conveyance, (Semi-) Centralized Treatment and Use and/or Disposal. It offers a collection of technology information sheets for different options along the entire service chain, as well as system templates for how the various technologies can be put together to form a complete system. While the Eawag Compendium does include information sheets for technologies that are designed for the reuse of sanitation products (e.g., application of compost), it provides little information on the characteristics of reusable products or on how resource recovery in technologies actually might be best implemented. spaces, including households, schools, restaurants, office building and factories. For a more detailed characterisation of faecal sludge, refer to Strande et al. (2014) 3 and Velkushanova et al. (2020) 4. Organics refer to biodegradable plant material (organic waste) that can be added to some technologies (e.g., composting chambers) in order for them to function properly. Organic degradable material can include, but is not limited to, leaves, grass, ash and market waste. Although other inputs in this document contain organic matter, the term "organics" refers to undigested plant material. Stormwater is the general term for the water that is collected from rainfall runoff from roofs, roads and other impermeable surfaces. It is the portion of rainfall that does not infiltrate into the soil. The quality of the stormwater depends on the surface that the runoff is collected from, but it generally contains insignificant amounts of nutrients and low levels of pathogens. The quality is influenced by the level of unimproved sanitation systems or practice of open defaecation in the area. Intermediary resource flows Sludge is a semi-solid slurry that is produced in a variety of technologies along the sanitation service chain (Figure 2). Due to large variations in how the sludge is produced, its chemical composition can be highly variable. Depending where it is captured in the service chain, it can include raw or digested excreta in combination with sand, grit and other materials that may have entered the sanitation system. Reject water is used as a blanket term to describe the water streams that are generated as by-products from both mechanical dewatering of sludge and the use of membrane filters. As such, reject water composition varies but it can generally be said to be a highly concentrated stream that is rich in nitrogen and phosphorus, although not yet safe for reuse.
In Rural Area “Solid and Liquid Waste Management”
2016
In the rural waste management has been regularly voiced in India. With the emerging concern on large quantity of the waste being produced both in the form of solid and liquid waste, the concept of waste management becomes one of the key focus of sustainable development principles which is based on policies, and practices that are resourceconserving, follow standards that can be met in the long term, and respect values of equity in human access to resources. There are in Rural area there is the waste management is very important because the people are suffering serious problems including the growth of water borne diseases such as diarrhoea, malaria, dengue, cholera and typhoid. In definitional terms solid and liquid waste management (SLWM) is the collection, transport, processing, recycling or disposal of waste materials, usually ones produced by human activity, in an effort to reduce their effect on human health or local aesthetics or amenity.
Household Waste Management Challenges
Engineering, Technology & Applied Science Research
Household waste and uncontrolled urbanization management are considered major problems in African countries. In the Hodna region, the phenomenon seems to be more important in urban centers because of the huge amount of household waste generated by domestic and commercial activities. In most Algerian cities, solid waste is piled up in huge quantities in dumps and is dumped indiscriminately in waterways and public spaces. Uncontrolled urbanization, industrial development, and the evolution of lifestyle lead to increased production of waste, whereas the waste management techniques used in urban areas should be reconsidered. From this perspective, this paper studies and analyses in a spatio-temporal approach, the practices of household waste management in the city of M’sila in order to evaluate the state of such management and identify the key elements of integrated planning of waste management.
The Use of Waste Management Techniques to Enhance Household Income and Reduce Urban Water Pollution
Bioeconomy [Working Title]
Appropriate waste management options are major concerns in the developing world. Current methods include incineration in the open and accumulation of wastes in designated places where they constitute nuisance to the environment. Apart from air pollution from the incinerators, leachates from decomposed wastes are either washed off where they serve as source of pollutants to the adjourning streams and rivers or contaminate groundwater through deep percolation. We present viable options for managing agricultural wastes in this chapter. The options presented are so simple and sustainable such that it can be managed by individuals. Hence, they are independent of the government bureaucratic bottlenecks that have been the bane of the previous government interventions. If embraced, it will also serve as sources of income for the concerned household, hence enhance their livelihood.
