Since 2017, a housing renovation program has been implemented in Moscow, which is a unique program aimed at settling and demolishing shabby low-rise housing stock and new construction on the vacated territory. The renovation program raises a fundamental issue of construction waste disposal. Many current technologies of building mass demolition imply dusting of adjacent territories, have low efficiency in transporting construction waste generated in this process and lead to environmental problems resulting from its disposal, so the rational use of construction waste becomes one of the environmental protection's main points. In this research, we address the question: how the principle "Green Digital Technologies," reflected in the Moscow development concept "Smart City," which is a part of the housing renovation program in Moscow, is currently implemented. Three implementation ways of this principle have been revealed: contraction of "smart houses" under the renovation program according to smart 1.0 standard; use of BIM-technologies in the program; use of "smart demolition" technology. It is proposed to consider the process of recycling construction waste after demolishing old houses under the renovation program according to the principles of sharing and circular economy to increase the program's environmental friendliness and reduce environmental risks for the Moscow population.

Net Zero

The European Union is working towards the 2050 net-zero emissions goal and tackling the ever-growing environmental and sustainability crisis by implementing the European Green Deal. The shift towards a more sustainable society is intertwined with the production, use, and disposal of plastic in the European economy. Emissions generated by plastic production, plastic waste, littering and leakage in nature, insufficient recycling, are some of the issues addressed by the European Commission. Adoption of bioplastics–plastics that are biodegradable, bio-based, or both–is under assessment as one way to decouple society from the use of fossil resources, and to mitigate specific environmental risks related to plastic waste. In this work, we aim at reviewing the field of bioplastics, including standards and life cycle assessment studies, and discuss some of the challenges that can be currently identified with the adoption of these materials.

Electro Mobility

The development of electro-mobility is one of the centerpieces of European country attempts to reduce carbon emissions and increase the quality of life in cities. The goals of reducing emissions from the transport sector and phasing out fossil-fueled vehicles in (urban) transport by 2050 present unrivaled opportunities to foster electro-mobility. This paper provides a comprehensive review of the literature and provides a detailed analysis of the current development of electro-mobility in Europe, assessing social, economic, and environmental aspects under a circular economy (CE) context. It also examines the existing challenges and suggests ways of addressing them towards improving the environmental performance of electro-mobility and the urban quality of life. The paper argues that a narrow technology-only agenda in electro-mobility will be less successful without the imperative of the CE, including not just materials and resources but also energy, to unlock the medium-term co-benefits of de-carbonization of both the transport as well as the building and energy sectors. The paper critically reviews some of the anticipated future developments that may guide the growth of this rapidly growing field into a CE.

Construction and demolition waste (CDW) accounts for at least 30% of the total solid waste produced around the world. At around 924 million tons in the European Union in 2016 and 2.36 billion tons in China in 2018, the amount is expected to increase over the next few years. Dumping these wastes in sanitary landfills has always been the traditional approach to waste management but this will not be feasible in the years to come. To significantly reduce or eliminate the amount of CDW being dumped, circular economy is a possible solution to the increasing amounts of CDW. Circular economy is an economic system based on business models which replaces the end-of-life concept with reducing, reusing, recycling, and recovering materials. This paper discusses circular economy (CE) frameworks—specifically material recovery and production highlighting the reuse and recycling of CDW and reprocessing into new construction applications. Likewise, a literature review into recent studies of reuse and recycling of CDW and its feasibility is also discussed to possibly prove the effectivity of CE in reducing CDW. Findings such as effectivity of recycling CDW into new construction applications and its limitations in effective usage are discussed and research gaps such as reuse of construction materials are also undertaken. CE and recycling were also found to be emerging topics. Observed trends in published articles as well as the use of latent Dirichlet allocation in creating topic models have shown a rising awareness and increasing research in CE which focuses on recycling and reusing CDW.

Over the last decade, private rental sectors have been in rapid ascendance across developed societies, especially in economically liberal, English-speaking contexts. The Netherlands, and Amsterdam in particular, has also more recently experienced the reversal of a century-long decline in private renting. More unusually, the expansion of private renting in Amsterdam has been explicitly promoted by the municipal and national government, and in cooperation with social housing providers, in response to decreasing accessibility to, and affordability of, social rental and owner-occupied housing. This paper explores how and why this state-initiated revival has come about, highlighting how new growth in rent-liberalized private renting is a partial outcome of the restructuring of the urban housing market around owner occupation since the 1990s. More critically, our analysis asserts that restructuring of Amsterdam’s housing stock can be conceptualized as regulated marketization. Market forces are not being simply unleashed, but given more leeway in some regards and matched by new regulations. We also demonstrate various tensions present in this process of regulated marketization; between national and local politics, between existing housing and new construction, and between policies implemented in different time periods.

The Cost

The author develops a simulation model to estimate the optimum timing and maximum impact of full rehabilitation of New Zealand housing stock. The model is based on the theories of classical population dynamics. Data used in the model include empirical estimates of the mortality of New Zealand housing stock, assumed schedules of depreciation of dwelling services, and assumed schedules of annual maintenance costs. The dwelling service years provided by dwellings serve as a proxy for benefits of rents or imputed rents (excluding rent for land). The cost to construct one dwelling and fractions thereof serve as a proxy for costs of maintenance, rehabilitation, replacement, and new construction. Optimum timing of rehabilitation can increase the quantity of benefits provided by the housing stock per unit total cost but a reduction in the growth rate of new dwellings has a greater impact in achieving the same objective. A stationary and stable housing stock can provide 45% more dwelling services per unit total cost than a housing stock which doubles in size every 35 years.

In the process of urbanization of large cities in different countries, there are similar problems of reorganization, involving the demolition of physically and morally obsolete buildings and structures, as well as the subsequent construction reorganization of the territories vacated or re-cut to the city. In the process of demolition of obsolete buildings and structures, as well as the construction of new buildings, inevitably significant amounts of waste and construction debris arise that should be recycled as much as possible into secondary building materials (to carry out the so-called «recycling» of waste). Types of construction reorganization of urban areas are divided into traditional, widely known and standardized (repair, reconstruction, restoration), and innovative, arising in the processes of reorganization of society. Among the innovative types of construction reorganization, renovation is currently the most relevant, meeting the need to renovate the dilapidated housing stock of cities. The article discusses the main types of construction waste generated during demolition and new construction, as well as the technologies used for recycling these wastes during the renovation of territories and pavements of large cities.

The Impact

Roads, like a spider web, intertwine our world up and down, and every day people build hundreds of kilometers of roadway, sometimes without even thinking about the environmental friendliness of road construction methods. The urgency of the problem of dirty road construction should not raise questions in our time, and especially in the Russian state. The article highlights the issue of reducing the risks of environmental pollution during the construction of the road network, the issue of green building is touched upon. Focal points are highlighted, which are worth paying attention to during the preparation of documentation to reduce the risks of environmental pollution. As a result, conclusions were drawn on the list of materials that should be used in order to reduce the impact on the environment.
