“…Article [4], for example, argues that drilling sludge can be used, after neutralization or hardening, in the manufacture of such building materials as bricks, ceramite, and other construction articles. The unresolved issue is the optimal content of sludge, which would not worsen the quality of the resulting products.…”

Oil production is currently impossible without drilling wells, so millions of tons of drilling waste contaminated with oil, chlorides, and heavy metals are generated every year in Russia alone. This article presents the results of a comparative life cycle assessment of water-based drill cuttings management technologies applied in Russia, including disposal, solidification, and reinjection. Life cycle assessment of the drilling waste management was performed using OpenLCA software, Ecoinvent 3.8 database and ReCiPe Midpoint (H) impact assessment method. Data from oil producing companies on the composition of drilling waste and information from drilling waste treatment companies on the technologies and reagents used were also applied. To compare alternative technologies the following scenarios were compared: Scenario 0 «Landspreading», scenario 1 «Disposal», scenario 2 «Solidification» (scenario 2a – in a waste pit, scenario 2b – without a waste pit), and scenario 3 «Reinjection». Sensitivity analysis was performed to test for variations in results for oilfields located in different regions. Results and discussion: The environmental impact of scenario 0 depends mostly on drilling waste composition, which is largely determined by human toxicity. In scenario 1, sand extraction and transportation, excavator and bulldozer operations were the most impactful processes. Among all scenarios, 2a and 2b have the biggest environmental impact in most categories. The production of cement and lime for drilling waste solidification was the main contributor to fossil depletion (64% of the total amount for scenario 2a and 54% for scenario 2b), and greenhouse gas emissions (49% of the total amount for scenario 2a and 70% for scenario 2b). The main contributor in scenario 3 is electricity production. Oilfield location does not affect the data for reinjection, but the impact assessment changes up to 60% for drill cutting disposal due to different waste pit design depending on permafrost and groundwater levels. Drilling waste landspreading is only the best option if the level of pollutants in the waste is very low. Among the other scenarios of drill cuttings management aimed at isolating pollutants from the environment, solidification technologies have the greatest environmental impact, primarily due to their use of binders. However, the application of soil-like material (solidified drill cuttings) as an inert ground in swampy areas can make migration of heavy metals possible. So, reinjection is associated with the least impact on the environment.

“…This also applies to the disposal of waste from such industries as production of phosphate mineral fertilizers, alcohol and dairy products. One of the effective ways to dispose of these wastes is to recycle them for production of building materials [6][7][8][9][10], in particular, aerated concrete products. The purpose of these studies is to develop compositions and a production technology for modified non-autoclaved aerated concrete based on recycled industrial waste.…”

Abstract. The purpose of these studies is to justify the feasibility of recycling different types of industrial waste instead of conventional expensive raw materials in production of environmentally friendly aerated concrete with required construction and operational properties. The impact of wastes from various industries on the environmental condition of affected areas, as well as the results of their environmental assessment were analyzed to determine whether these wastes could be used in production of high-performance building materials. The assessment of industrial wastes in aerated concrete production suggests that industrial wastes of hazard class IV can be recycled to produce aerated concrete. An environmentally friendly method for large-scale waste recycling, including a two-step environmentally sustainable mechanism, was developed. The basic quality indicators of the modified aerated concrete proved that the environmental safety could be enhanced by strengthening the structure, increasing its uniformity and improving thermal insulation properties. The modified non-autoclaved aerated concrete products with improved physical and operational properties were developed. They have the following properties: density -D700; class of concrete -В3.5; thermal transmittance coefficient -0.143 W/(m°С); frost resistance -F75.
