Polymeric materials of secondary industry in bridge engineering
AI summary Read the abstract
This review examines how recycled plastic waste can be repurposed as a structural material in bridge engineering, comparing secondary polymeric materials to traditional concrete, steel, and wood, and arguing that plastic recycling offers both environmental benefits and competitive construction economics.
The article discusses the impact of plastic waste on the environment, disposal methods, and the problems of isolation from the total waste amount. The technology of its recycling is described, as well as the properties of the materials obtained, pros and cons relative to analogs from traditional materials (concrete, steel, and wood), the foreign experience of its use in bridge engineering (construction of new bridges, reconstruction of old bridge structures). The article also analyzes the economic component of construction using building materials from plastic waste and its impact on the environment. A comparison is made of materials from primary polymers and secondary industry polymeric materials. It is shown how things are with plastic waste recycling abroad and in Russia, and what systems are being developed to improve and optimize the recycling process. The purpose of the article is to point out that humanity needs to reconsider its view of the environmental situation in the world, due to environmental pollution with plastic waste, and to show that there is a way to solve this problem and it is recycling plastic waste. This option of recycling plastic waste will allow us to clean our planet from accumulations of plastic waste (which is formed both on land and in the ocean, adversely affecting flora and fauna) and create competitive, reliable building materials and products that will speed up the process of building bridge structures, facilitate and make more economical the operation of bridges in the future.

A Review on Sustainable Bridge Construction Using Recycled Materials for Environmental Protection
AI summary Read the abstract
This review paper explores using recycled plastic and fiberglass waste (instead of sand or gravel) to help build stronger, eco-friendly bridges and roads. While this isn't a direct human health study, it matters because it points to ways of keeping non-biodegradable plastic waste out of landfills and waterways, which could reduce environmental pollution and long-term microplastic buildup in soil and water sources we rely on. Note that this paper summarizes existing research and proposes a study design rather than reporting final results.

Recycling/reuse of plastic waste as construction material for sustainable development: a review
AI summary Read the abstract
Researchers reviewed how waste plastic can be incorporated into construction materials — as binders, aggregates, or cement substitutes in bricks, tiles, concrete, and roads — finding that plastic-modified materials often show competitive strength properties while simultaneously diverting plastic waste from landfills.
Recycled Plastics in Building Materials: Enhancing Sustainability and Economic Efficiency
AI summary Read the abstract
This review examines the use of recycled plastics as components in building materials, including concrete, insulation, and composites. Incorporating plastic waste into construction can divert material from landfills while offering benefits such as reduced weight and improved thermal properties. The paper also addresses challenges around durability, regulatory acceptance, and the environmental trade-offs of plastic-enhanced building products.
