Waste and efficient waste management are an essential part of sustainable cities. In developing countries, incorporating this area into urban infrastructure can cover the management of excess waste and also add a source of energy.
Landfills are still being built because they are the cheapest way to dispose of solid waste. However, various analyses are required before construction can begin.
Recycling at least the basic types of recyclable materials is a well-known way to work with waste and reduce the volume of waste suitable for landfill. It should be noted, however, that it is important to prevent waste in the first place and to choose appropriate products to purchase.
In the absence of a monitoring system for basic commodities such as water and general waste in most developing cities, hazardous waste management is partially unregulated. In many cases, hazardous waste management requires a specific approach and adaptation of disposal technology.
One way to mitigate (weaken) the climate impacts of the energy industry is through a system of shared electricity networks, called energy communities. This system is based on local generation and sharing of surplus electricity produced within the local community.
Adaptation is primarily concerned with critical locations where climate change is likely to occur in the coming years to such an extent that the population or the infrastructure of the city as a whole would be at risk. Therefore, innovative technologies are used in these locations to minimise the risks.
The carbon footprint is a fundamental parameter for classifying the current state of cities, businesses and industry. The decarbonisation of as many processes as possible will lead to the carbon neutrality we want to achieve.
Until a resilience infrastructure is in place, the city must rely on temporary solutions of a more natural nature, citizen education and an early warning system for natural disasters in a critical area. If a natural disaster strikes an area, there are important technologies that will ensure faster recovery of the damaged area.
Solar and wind power are the most commonly used methods of generating energy from renewable sources. Most developing countries are geographically suitable for the use of at least one of these technologies.
Luminaires connected to photovoltaic cells placed directly on the luminaire can greatly simplify access to public lighting, even in remote areas, and thus increase safety in the area. Excess stored energy can be sent to nearby households.
The modern electricity distribution network leads to the involvement of consumers as partial energy producers in the network. The energy produced in this way comes from local renewable energy sources. This concept can be linked to the concept of energy communities.
Detailed research of water resources is an essential part of the preparatory stages of building blue and green infrastructure. Each city, its inhabitants, and the industries present depend on the presence of uncontaminated water sources to determine how large a city can be or how much industry it can subsidize with water. The amount of usable clean water determines the overall prosperity of a city.
Everyone needs water for their daily life, whether for drinking, basic hygiene or household chores. But the problem arises when there is only a limited amount of water available and you have to wait at least 30 minutes to get it.
Despite its complexity, the treatment plant is essentially a long-term and cheap technological solution to get rid of human bio-waste. The substrate is pre-treated in the primary treatment vulture, but a significant part of the treatment technology is provided by the biological phase, and therefore by bacteria.
Waste heat from industrial plants is one of the underused sources of energy for local communities. This sustainable energy source is socially beneficial. For cities in developing countries, it is an advantage in terms of local infrastructure and the use of local resources.
Urban water and overall urban blue infrastructure is an essential part of functioning systems, industry and prosperity. Rainwater harvesting can contribute to urban cooling and simplify access to easily treated and otherwise usable water.
Industrial wastewater often contains more complex pollutants and therefore companies are obliged to pre-treat the wastewater present as a minimum.
If the sewerage network is built centrally, sewerage is one of the cheapest solutions, despite the high initial costs. It provides a long-term and hygienic way of transporting biological waste to the site for further treatment.
The most efficient way of modern agriculture is the concept of urban agriculture, where all resources are used as much as possible, local food production is accommodated and thanks to open gardens we can talk about contributing to urban greenery.
All steps towards a sustainable city must start with the right authorities. Green procurement is a good way to achieve this and improve the situation of companies involved in improving cities.
Innovative technologies are also associated with the concepts of digitisation and automation.
Replacing existing means of public transport with environmentally friendly alternatives is an important step towards a sustainable city.
Due to the concentration of infrastructure, the city is noisy day and night. Encouraging the replacement of vehicles moving around the city will also help to reduce road noise in the city. Other types of noise reduction are also used, such as green infrastructure.
As urbanisation increases and the number of people, cars and businesses grows, air pollution is also increasing. In critical cases, air pollution leads to deaths of residents.
With sufficient public transport infrastructure, the city can ensure reduced emissions and increased traffic flow, which has a major impact on the functioning and status of the city.
One of the most widespread modes of green urban transport is rail vehicles, trains and trams.
Parking will usually show whether a city is ready for new people to arrive. The current strong urbanisation is causing problems of this type everywhere in the world.

Waste could be one of the potential renewable energy sources if properly treated. Currently, waste-to-energy (WtE) is one of the promising technologies that is well established in developed countries. However, it has only been applied to a very limited extent in developing countries.
Waste-to-energy is one of the newest forms of waste treatment that offers a number of advantages. It can generate electricity using various technologies such as incineration, pyrolysis or anaerobic digestion. The production of this energy helps to reduce greenhouse gas emissions and new facilities also create new jobs. This offers a more efficient waste management system that will contribute to sustainable development.

Waste is a raw material. In order for waste to be an economically and industrially recoverable raw material, it must be kept separate from each component. Material recoverable components include paper, plastics, glass, metals, bio-waste and textiles, or beverage cartons.
We can also design new policies and programmes to use organic waste as a resource. This can be composted or processed in an anaerobic facility to create valuable products (e.g. compost, biogas) that can be reused or sold by cities or their residents. For example, home composters are a simple solution for local residents.

(hazardous wastes such as those associated with mineral extraction and processing)
In developing countries, it is very difficult to control the real amount of hazardous waste. To a large extent, these wastes are improperly managed, which is likely to have a greater environmental impact than reported. We are able to help cities to identify the main problems and risks, prepare a proposal for a solution for the treatment and disposal of these wastes and then deliver or build the technology, also awareness needs to be raised among citizens. The services offered include, for example, decontamination of waste through the application of biotechnological (biodegradation, composting, etc.), physical (stabilization/solidification, washing, etc.) and chemical (oxidation, neutralization, etc.) techniques. ) methods, treatment of liquid waste disposal of hazardous waste in contracted landfills and incinerators, collection and transport of waste conversion of waste into alternative fuels recycling and material recovery of industrial waste remediation and reclamation of landfills supply of equipment for waste treatment by stabilisation/solidification, thermal desorption, washing, pelletization, etc.

The set of adaptation measures is based on the current climate change situation. These measures include preparation for possible local situations (renovation of buildings, preparation for sea level rise, forest fires or floods). To be effective, adaptation requires cross-sectoral cooperation at local level. Successful adaptation prevents loss and damage caused by climate stressors, saves money and unlocks the economic and social potential of the urbanised area.

Consumer lifestyles have a significant impact on the production of greenhouse gas emissions and thus on the carbon footprint of shops and stores, urban transport and public and private buildings. This trend can be observed especially in places with high population density. Decarbonisation is a major tool for mitigating the increase in emissions, where replacing the predominant non-organic energy sources with renewable sources would significantly reduce emissions. In addition, decarbonisation also involves improving the efficiency of existing systems.

First and the most effective way to reduce the impact of natural disasters in cities is to prepare and educate citizens. This is followed by the development of early warning and prediction systems for these disasters. However, in order to prevent or reduce the actual damage caused by a disaster, mitigation measures such as land use planning, land use practices such as creating wetlands, rain gardens, planting trees and building other infrastructure to help avert potential hazards are needed. Preparedness will certainly mitigate the impact of disasters and also applies to urban amenities such as multifunctional barriers, reservoirs, etc. For example, IGPE’s barriers are useful for temporary storage of utility water, for example after a tornado. The same use can be realised during water supply failures in large conurbations, for fighting forest fires or large-scale grass fires. In terms of hazmat and oil spill applications, barriers can be used for temporary storage of contaminated liquids or materials.

Developing countries very often have suitable natural conditions for solar and wind technologies.
Solar energy can be used passively and actively. Passive use means so-called solar architecture, i.e. adapting buildings to the climate. Solar energy can be converted into heat (e.g. to heat water) and electricity. As a continent, Africa has great potential for electricity generation using photovoltaic power plants, especially in the Sahara, which covers up to one third of Africa’s landmass. Photovoltaic power plants are being installed all over the world, ranging from small systems to large plants with a capacity of several tens of MW.

The modern version of the electricity distribution network is the smart grid. It is a grid based on several main methods. The energy that passes through the grid must come from renewable sources (wind, water, solar, anaerobic digestion) from multiple smaller suppliers. The grid must be built in a decentralised way to avoid blackouts. The functioning of the grid is also supported by all consumers, who sell surplus energy back to the grid after filling up domestic batteries for their own consumption. This is based on a mutually beneficial contract with the grid operator. A smart grid must also include control points that adjust the amount of energy flowing to avoid overloading the grid.

Hydrogeology can determine the strategic location of a city, especially with respect to water resources and their scarcity. Access to a groundwater source ensures a continuous supply of quality drinking water.
Some urban locations, particularly industrial areas, may have been affected by improper management of hazardous industrial waste, which may have caused significant environmental contamination, whether of surface water, groundwater or soil. Today, there are many companies that deal directly with environmental loads, either on behalf of the competent authorities of the Ministry of the Environment or directly by the companies responsible for the environmental load.

Increasingly, we are witnessing urbanisation, even at the cost of incomplete or inaccessible utilities in the outskirts of cities. This scarcity is often addressed by supplying drinking water, either in the form of bales or tankers.
The construction of water supply systems and reservoirs ensures a continuous supply of drinking water in cities without waiting in queues. The construction of utilities can cover a large percentage of the remaining urban population who wait more than 30 minutes for water or depend on water from polluted sources.

The heat comes from industrial processes. The steam used after leaving the production process heats water for further use by citizens or for heating buildings. The hot water that is transported to consumers (residential and multi-functional buildings and the municipal sector) is piped in mainly underground pipes. The piping enters the buildings through underground pipes and branches out to individual heating elements in the building. A system designed in this way only works up to a certain distance from a suitable industrial installation, provided that the outlet water temperature is sufficient and within agreed parameters.

Urban agriculture or farming has the potential to address a number of key urban challenges. In predominantly African cities, urban agriculture already exists. However, the systems set up often only cover the needs of a given farmer. But it has enormous potential to develop further. Urban agriculture is about setting up food operations within the city; for example, through integrated agriculture, including concepts such as aquaponics, indoor farming, vertical farming, rooftop production, edible walls, as well as through urban farms, edible landscapes, school gardens and community gardens.

Nowadays, it is hard to imagine a city without a functioning infrastructure. When we talk about sustainable transport, we must not forget the basic pillars of its functioning. Equal access opportunities for people from all socio-economic groups, as well as the efficiency of transport, its safety and the pollution it produces and its minimisation. This area is also linked to the introduction of innovation, electrification and the use of new, cleaner fuels. Sustainable transport in cities also includes walking and cycling.

Noise is much more concentrated in cities than in their surroundings. Long-term exposure to urban noise can cause chronic hearing damage at exposures above 70 dB (2). This level of noise can easily be reached at a busy intersection, but also in the home environment if appliances are not soundproofed (3), and it is therefore very important to pay attention to this human and environmental hazard factor through soundproofing technology, the use of electric vehicles or street landscaping, which can be accompanied by tree planting.

Air pollution is on the rise, precisely because of the ever-growing population and rapid urbanisation. If it were possible to reduce emissions of particulate matter below 10 nm, one of the most polluting substances, from the current 70 µg/m3 to the WHO standard of 20 µm/m3, it is estimated that human mortality due to air pollution would fall by around 15 % (4). The main sources of current air pollution are transport, energy production and industrial plants.

The quality and quantity of public transport services is crucial for the flow of traffic in cities, which directly affects the modal split and emissions of the different modes of transport used in cities (1). The more public transport is used, the less congestion there is in a city and the faster and smoother the traffic flow. Increased use of public transport also reduces emissions, as a large number of public transport vehicles in cities are electrified.
