Recently, experts at Novgorod State University systematically reviewed the possibilities of using recycled materials to produce construction materials, reaching an important conclusion: it is entirely feasible to build a detached house using materials made solely from household waste and industrial byproducts.

Project supervisor Olga Naumova, associate professor in the Department of Construction Production at the Novgorod Polytechnic Institute, commented: "Using sorted recycled waste, it is possible to produce concrete mixtures, gypsum particleboard, wood particleboard, cinder blocks, and wood bricks—and even make them yourself. Of course, the environmental safety and toxicity of secondary raw materials must be considered. However, the existing waste on Earth is already sufficient to manufacture all materials available on the DIY market."

Buildings constructed with recycled materials offer significant advantages, including high material strength and outstanding cost-effectiveness. Individual developers can use cheaper construction materials without purchasing new ones. Olga Naumova added: "Our work aims to draw developers' attention to this fact, helping people change their attitude toward solid household waste and construction debris, and reuse them for profit."

In their analysis, the students examined types of recycled raw materials that can be used to produce construction, finishing, and landscaping materials, providing reference information, photos, and environmental safety guidelines. Additionally, the team conducted laboratory experiments, testing concrete cubes made from ordinary concrete and from concrete with large crushed brick aggregates. The results showed that the strength of crushed brick-based concrete is only 14% lower than that of ordinary concrete, meaning it can be used as a structural material for low-rise buildings. Currently, the price of ordinary crushed stone is about 1,500 to 1,800 rubles per cubic meter, while the same volume of crushed brick can be obtained for free, and crushed brick can perfectly replace large aggregates in concrete mixtures.
