http://ijaers.com/ Open Access international Journal to publish research paper en-us With millions of tons of materials discarded annually during production, the fashion sector is one of the largest contributors to textile waste worldwide. Zero-waste fashion design (ZWFD) aims to eliminate waste at every stage of clothing production. This study explores ZWFD concepts and methods, focusing on reducing material waste during production. The research examines design approaches including zero-waste patterns, fabric optimization, and upcycled materials. It also analyzes technical breakthroughs such as digital pattern-making and automated production. Using a mixed-methods approach (consumer survey, n=280; designer interviews, n=15; expert interviews, n=10; case studies, n=5), this study assesses environmental, economic, and social dimensions of ZWFD. Results show that while consumer awareness of ZWFD is moderate (57.9%), willingness to pay a premium remains low (27.9%). High prices (70.7%) and limited design variety (40%) are the primary adoption barriers. Scenario-based environmental indicators suggest ZWFD could reduce textile waste by 66.7% and carbon emissions by 37.5% compared to conventional production. The study contributes to sustainable fashion literature by providing empirical data on consumer perceptions alongside technical environmental estimates. http://ijaers.com/detail/zero-waste-fashion-design-minimizing-material-waste-in-the-production-process/ Md Kowsar Alam Sarker, Liu Lixian, Md Yousof Talukdar http://ijaers.com/uploads/issue_files/1IJAERS-04202612-Zero-Waste.pdf The article presents a comparative assessment of the energy efficiency of cyclic high-pressure reagent injection systems and continuous-operation plunger pumps used for anticorrosion protection of oil and gas well equipment under high pressure, elevated temperature, and chemically aggressive multiphase media. The relevance of the study is determined by the need to solve simultaneously two interrelated tasks: maintaining a stable protective inhibitor film on the metal surface and reducing energy, material, and operating costs associated with reagent dosing. The aim of the work is to provide scientific and techno-economic substantiation of the advantages of cyclic dosing over traditional continuous and periodic injection schemes. The scientific novelty of the article lies in the integrated comparison of three technological approaches based on operational, economic, and physicochemical parameters, as well as in the interpretation of intermittent injection efficiency in terms of adsorption kinetics and the film lifetime effect. It has been established that cyclic systems maintain anticorrosion efficiency at 94% while reducing commercial inhibitor consumption by 73.6%, decreasing energy consumption, lowering pump equipment wear, and diminishing total operating costs. It is shown that switching pumps to a short-time, repeated-duty operating mode using hydraulic accumulators and intelligent control results in a more rational and technologically stable reagent injection regime. The article will be useful to researchers, oil and gas engineers, specialists in corrosion protection, automation, and energy-efficient technologies for field infrastructure. http://ijaers.com/detail/assessment-of-the-energy-efficiency-of-cyclic-high-pressure-reagent-injection-systems-compared-with-continuous-operation-plunger-pumps/ Ilnar Iakhin http://ijaers.com/uploads/issue_files/2IJAERS-0520262-Assessment.pdf
