Green retrofitting – A review of current status, implementations and challenges

Towards Sustainable Development: A Review of Green Technologies

“…With current green technologies being implemented in water treatment process, most water treatment plants use advanced filtering systems such as Nano filters and membrane filters [7,10]. These filters trap minute particles [11].…”

“…The remedy was to use green technologies such as chlorination, safe can storage, filtration and solar treatment. Such a sustainability of water has been achieved in many countries [1,10,11].…”

“…The knowledge of the sewerage treatment has evolved from early centuries. In the modern society, green technologies have been encompassed in this field to help removing physical, biological and chemical contaminants from the effluents to make them eco-friendly [11]. Wastewater treatment has a significance in that it allows the water from the industries to be treated before being discharged back to the environment [8,9].…”

“…Green technologies have ensured that the wastewater produced by the industry and homesteads can be used in other areas such as irrigation and livestock watering in arid and semi-arid areas after the treatment [11]. As manufacturing industries are being designed, many have found the importance of creating a recycling plant within the same plant to cut on the cost of wastewater management [6,10].…”

“…Air pollution is the introduction of harmful chemicals and GHGs into the air. They result in human and animal diseases and end results are a damage to the atmosphere [11,17]. Air pollution is believed to be because of human struggle to achieve development.…”
