RECYCLING AND WASTE MANAGEMENT
The amount of waste produced is an increasing problem all over the world due to increased populations and consumption. It is getting imperative to reduce the amount of waste produced, and recycle as much as possible to minimize the amount of waste ending up at landfills.
Sweden is a world leader in waste management - 99% of all household waste produced is recycled or recovered as energy and only 1% ends up at landfills.
WASTE AS A RESOURCE - WASTE TO ENERGY
Example of a holistic solution including a water treatment plant with integrated resources and management for production of biogas from digested waste and water sludge.
LANDFILL GAS RECOVERY FOR ENERGY PRODUCTION
Many landfill sites containing organic material is leaking landfill gases to the atmosphere in the form of carbon dioxide and methane. Methane is a greenhouse gas that is 34 times stronger than carbon dioxide if compared over a 100-year period.
Correctly used the methane can be recovered for energy generation and become a valuable and environmentally friendly source of energy for heating and generating electricity. Smell and spontaneous fires will also be dramatically reduced.
A renewable energy system is a cornerstone in the development of a climate favorable neighborhood which means that buildings, infrastructure and transport must be based on highly energy-efficient systems and renewable energy sources. A renewable energy system also requires a stringent management of scarce energy resources and low environmental impact of the extraction and use of energy. In a climate positive development also plays recycling solutions with energy recovery of local waste resources such as biogas play an important role.
WATER & WASTE WATER
Water, like air and food, is our life support. It covers about 70% of the surface of our planet. But only 2.5% of it is fresh water, the rest being ocean, with a small fraction of that being available as drinking water. As a fragile resource, water must be nurtured with investment, management and care. From oceans and vast rivers to the spring in the garden, we must safeguard our water as a source of well-being, prosperity and progress. We must turn water into a flow of new opportunities for green, inclusive, sustainable growth.
Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients.
In order to create a sustainable transport structure, the city shall have a well-planned traffic hierarchy where street space clearly indicates the priority of the Transport Act: walking and cycling, public transport/freight (environmentally efficient vehicles), and environmental cars such as electric or biogas driven cars shall have a priority. Will fossil driven cars and motorbike be allowed?
SMART CITY / ICT
A smart city is an urban development vision to integrate multiple information and communication technology (ICT) and Internet of Things (IoT) solutions in a secure fashion to manage a city's assets – the city's assets include, but are not limited to, local departments information systems, schools, libraries, transportation systems, hospitals, power plants, water supply networks, waste management, law enforcement, and other community services.
