Abstract Lean and Green seeks to increase added value and reduce waste generation, while also improving environmental sustainability performance in production activities. However, no studies were found exploring the potential results by combining Lean and Green with eco-efficiency assessments in the construction sector. Therefore, this paper aimed at proposing and testing a Lean and Green approach in three steps. Step 1 was based on the Value Stream Mapping application to calculate the Value Added of construction activities; step 2 focused on the Life Cycle Assessment of evaluated construction activities, and step 3 performed an eco-efficiency assessment of construction sites to guide decision-makers on selecting more lean and sustainable construction materials and strategies. A case study was developed for a 300m²-house construction considering two build options (reinforced concrete frame vs. light steel frame). The results affirm that light steel framing showed a Value Added 43% higher than the reinforced concrete in step 1, whilst having 8% less Global Warming Potential impacts in step 2. Step 3 concluded that light steel framing was 1.38 times more eco-efficient than the concrete structure. The proposed approach can be suitable for any building system evaluation in terms of construction technologies, materials, and/or production strategies and investigations towards more sustainable production.

PurposeThe purpose of this paper is to introduce a new methodology called overall greenness performance for value stream mapping (OGP-VSM). Using value-added concepts, this approach has the potential to integrate, measure, control and improve productive and environmental performance in accordance with a company’s context.Design/methodology/approachThe OGP-VSM approach was developed by reviewing and integrating the environmental aspects of existing lean thinking tools and approaches.FindingsThis research revealed the lack of practical integration between productive and environmental performance. Using OGP-VSM, managers can see that environmental practices have a direct impact on productivity. OGP-VSM allows a balance to be found between lean and green practices in order to achieve the simultaneous improvement of productivity and environmental performance.Practical implicationsThe proposed approach is applied to a case study in an automotive company in Spain and lays the groundwork for moving toward functional environmental sustainability in manufacturers.Originality/valueCompanies are increasingly implementing environmentally focused practices. Pursuing environmentally friendly (green) performance poses several challenges, but it also affords opportunities to create new methodologies for generating a competitive advantage for manufacturing companies. There are a limited number of approaches to drawing together the elements and attributes that are essential for a holistic, practical and long-lasting improvement of environmental performance in the manufacturing sector.

Integrative Assessment

Bioeconomy regions are a young concept representing emerging amalgamation points for the implementation of cross-sectoral value-added chains. When sustainable bioeconomy strategies are rolled out, their proof-of-concept implies that industrial R&D activities should lead to impact decoupling and that the valorization of locally available lignocellulosic biomass has to contribute to an increase in added value. Furthermore, regional co-benefits for society and a positive influence on local environmental and socioeconomic conditions are major factors. The fulfillment of these strategic goals would be a milestone achievement when progressing from the blueprint development and the road-mapping stage towards socially accepted and sustainable wood-based bioeconomy strategies. For regional industrial and science stakeholders who run pilot facilities for process upscaling and for energy and material flow integration, this requires well-orchestrated integrative processes, which go beyond conventional “Life Cycle Management” approaches. It is obvious that assessing and monitoring such integrative systems will have to account for different stakeholder perspectives and for detailed technology deployment and resource conversion scenarios. Applying a sustainability index methodology in a case study region must include an evaluation of the whole supply chain and the process networks associated with the characteristic products of the evaluated region. To date, no such integrative assessment methods exist in the literature. Therefore, the aim of this paper is to lay out, on the basis of a practical example in the case study region of Central Germany, an assessment of the sustainability level of wood-based bioeconomy networks by applying the Sustainability Monitoring Tool -SUMINISTRO”- to examine regional bio-based industry networks.

Productivity is an important parameter for all small and medium scale manufacturing industries. Lean manufacturing emerged as production strategy capable of increasing productivity by identifying and eliminating non value added activities. This article deals with productivity improvement in a pre-assembly line of gearbox manufacturing company with a case study using lean concepts like process flow chart, process Gantt chart and time study. This paper illustrates using a case study on how a value stream mapping has to be carried out in a planet carrier pre-assembly line. Value stream mapping and work standardization are the key tools used in lean manufacturing and lean transformation. It makes the process smoother, helps in reduction of lead time and ultimately increasing the productivity. From the observed results it was found that, the productivity has been increased from 7 pieces to 10 pieces in the first step assembly when the proposed VSM was implemented. The second step processing time was reduced by the execution of proposed value stream mapping with TAKT time of 126 minutes and 165 minutes of processing time for demand of 10 pieces were achieved and the overall processing time has been reduced by about 24%.

Abstract Engineering science in the China of 1901-40 had unique characteristics that disrupt the idea of a universal approach to its history.1 The following case study describes the ideas and trials of introducing bamboo into the seemingly globalised technology of reinforced concrete—an innovation developed across the borders of mechanical, naval, civil, and aeronautical engineering. The article showcases a way of knowing and working by twentieth century engineers that has not been fully acknowledged, and is not only a phenomenon of China. While bamboo was a complicated and somewhat marginal object for engineering, it did make the European concrete technology more viable in the construction sites of China, and stimulate engineers’ experimental and resourceful spirit in mobilising both craft and scientific knowledge. It also opened up a challenge to engineering science of the time.

Introduction. Pharmaceutical service optimization requires a comprehensive understanding of resource usage. The aim of the study is to analyze how Lean Healthcare principles can contribute toward turning a pharmacy service patient-centered and value oriented. Methods. Understand how clinical pharmacists’ resources are effectively used by patients in an academic hospital using lean tools, such as value stream mapping and activity designation matrix, determine the amount of time each professional is involved in specific activities, and identify activities that add value. The data were mainly obtained through interviews with professionals, time-motion observational studies, chronoanalysis and meetings with the head of the unit. Results. A process flow map is designed for clinical pharmacy services, and it considers the relationship between the activities and their added value base. An exploration of the map shows that the activity “clinical rounds” is the most time consuming (27%) and not necessarily considered value-added by both parties (pharmacists staff and head of service). It is notable the opportunity the service has to prioritize the high-risk patients and to make a good time management; furthermore, activities that are of high value to patients are being performed and monitored by interns. Conclusions. The role of pharmacists should evolve from now on to be congruent with the new realities of healthcare. When value is questioned, we are encouraged to reflect on the activities engaged in by professional pharmacists in a clinical/surgical unit of a hospital. Through these tools, we could infer how the system is engaged and how it can be transformed toward added value.
