The problem of textile waste generated in production processes poses new challenges for manufacturers. For this reason, an approach to clothing design has been developed that takes into account aspects of sustainable development and the zero-waste concept. The paper presents the development of “T” and “X” silhouettes for women’s dresses according to the proposed new method. The existing basic cuts of women’s dresses were modeled to obtain “T” and “X” basic silhouettes for women’s dresses, and we compare the reduction in losses between the cuts using the newly proposed TAXI method and the TAXI method according to the proposed design. The use of pattern losses based on the pattern of the basic dress cut provides innovative design solutions according to the TAXI method by applying structural elements that adjust the shape of the basic silhouettes of women’s dresses. Fabric utilization using the basic “T” silhouette cut model is reduced to 75%. The TAXI method improves fabric utilization, achieving 75% fabric use with the basic “T” silhouettes and up to 99.8% with modifications. The fabric utilization of the basic “X” silhouette according to the proposed TAXI design method is 99.8%, which is 32.5% higher than the fabric utilization according to the basic pattern. With this comprehensive concept based on the principles of sustainability, the proposed TAXI design method has been adapted for the maximum possible fabric utilization, esthetic quality and fit, while retaining the recognizable silhouette of the garment.

Promotion of durable materials and products is a common approach to enhance sustainability. However, the effectiveness of such efforts lies on shifts in user behavior and consumption patterns, and these patterns are influenced not only by material aspects but also by social and experiential dimensions. It has been observed that the consumers’ consumption pattern, i.e., post-consumption behavior, is as harmful as production. However, this area remains largely unexplored. The primary purpose of this study is to explore sustainable garment design strategies to enhance emotional durability of garments and reduce pre-consumer and most importantly, the post-consumer waste. For this purpose, 18 garments were produced using ZWPC for pre-consumption waste reduction and DFD for post-consumption waste minimization. Three hypotheses were developed. Quantitative and qualitative data were collected through questionnaires and wear trials on the practicality of DFD implementation in garments. The results demonstrated that the combination of these strategies has the potential to curb both pre-consumer and post-consumer waste by designing garments that can enter the biological as well as technical cycle of circular fashion (CF). Furthermore, DFD is a success in increasing the use-life of a garment. Full article

While various approaches have been developed to minimize rebar cutting waste, such as optimizing cutting patterns and the lap splice position, reducing rebar usage by minimizing the number of splices remains uninvestigated. In response to these issues, a two-stage optimization algorithm was developed that prioritizes the use of special-length rebar to achieve a near-zero rebar cutting waste (N0RCW) of less than 1%, while also reducing overall rebar usage. The two-stage algorithm first optimizes the lap splice position for continuous rebar considering the use of a special-length rebar, which reduces the number of splices required. It then integrates a special-length minimization algorithm to combine the additional rebar. The algorithm was applied to beam structures in a small-sized factory building project, and it resulted in a notable reduction of 29.624 tons of rebar, equivalent to 12.31% of the total purchased quantity. Greenhouse gas emissions were reduced by 102.68 tons, and associated costs decreased by USD 30,256. A rebar cutting waste of 0.93%, which is near zero, was achieved. These findings highlight the significant potential of the proposed algorithm for reducing rebar waste and facilitating sustainable construction practices. The algorithm is also applicable to other reinforced concrete projects, where the associated advantages will be amplified accordingly. Full article

The implementation of standardized grading production practices within the mass market has been challenging for scholars experimenting with zero-waste apparel design. The purpose of this research was to test the efficacy of the Carrico Zero-waste Banded Grading (CZWBG) technique, which utilizes bands inserted in strategic locations as a method of grading zero-waste patterns across various consumer categories. An additional purpose was to evaluate the ways in which this grading approach affected the aesthetic outcomes of garments across a size run, and to determine whether this method affected the overall design process of the designers involved. Through experimental research design, six design scholars successfully tested and incorporated the CZWBG technique in zero-waste one or two-piece apparel item(s), subsequently developing three sizes in an industry-specified size range for their product category. Each design was cut from zero-waste patterns in a mid-range size and graded up and down one–two sizes using an industry-standardized grading scale. The grading was achieved by varying the widths and lengths of strategically inserted bands of fabric or trim. The designers utilized various grading methods, textiles, pattern development methods, and size runs, showing that the CZWBG technique can successfully be applied across multiple consumer categories in the apparel industry.
