The large number of industrial kitchens and their energy-intense characteristics provides opportunities for pollution prevention. Life cycle assessment (LCA) is a proper tool not only for unitizing the environmental impact of the complex system of an industrial kitchen, but also for making environmental food labels for the foods produced in the same industrial kitchen. In this study, a gate-to-gate LCA of 11 types of food was conducted to evaluate the environmental impact of a typical industrial kitchen, Villanova University’s Donahue Hall. First, material and energy flow data, including cold storage, food preparation, food display, lighting, heating, ventilation, and air conditioning (HVAC), and dish washing were collected. This data, along with standard data on energy generation and transmission, were used in the LCA. The results show that global warming, fossil fuel depletion and ecotoxicity are the main environmental impact categories. Furthermore, HVAC, cold storage and cooking are the three largest contributors of environmental burden. Using the metrics developed, tuna salad, tomato soup and pasta are the most environmental friendly foods of the 11 sampled food types, while pizza and cheese quesadillas have the worst environmental performance. Energy saving measures for HVAC, cold storage and cooking are proposed.

Life Cycle Analysis (LCA) is a procedure used as an analytical tool for the evaluation of the environmental impact caused by a material, a manufacturing process or product. For an end product, LCA requires both the identification and quantification of materials and energy used in all stages of the product’s life, together with their environmental impact. It requires therefore a huge amount of data about materials, components, manufacturing processes, energy consumption and the relevant environmental impacts. For this reason, a number of software and databases have been developed, in order to facilitate LCA users. These are the so-called Eco-Tools, used in an effort to minimize the environmental impact of a product from the materials and the energy used for production. In this paper, LCA is conducted for solar thermosyphonic systems, with the aid of three commercially available Eco-Tools, usually used by LCA practitioners, namely: Eco-It, GEMIS and SimaPro, and the results are compared. Although all three tools claim accordance with the international standards and guidelines, differences do exist. A typical solar thermosyphonic system (DSHWS) with a 4 m2 collector area and a capacity of 150 dm3 that covers the hot water needs of a three person family in Thessaloniki is used as case study. The results of the three tools are compared for each component of the solar system as well as for each material used and for the conventional energy substituted by the system.

This paper proposes a proactive model to improve the overall performance of construction processes. The main advantage is that potential waste and associate impacts could be identified in the early stages of a project before the construction phase. To accomplish that, the model combines three methods; Lean-to identify waste, Green to assess environmental impact, and Six-Sigma to measure and improve process performance (LG6). The LG6 model helps in evaluating processes one step at a time, identifying consumed resources, analyzing the environmental performance of all steps as well as highlighting generated impacts, applying improving alternatives if needed, and measuring process performance for evaluation. The functionality of LG6 is illustrated through a case study of woodpiles installation. In this case study, the LG6 model identified four steps out of eight that are considered potential waste or (non-value-added steps) according to the Lean principles. As a result, the LG6 model helped in reducing impact by 9% and expenses by 1%. The LG6 model can help to improve the performance of construction processes and reduces unnecessary waste.

Sotol is a Mexican distilled spirit produced in Northern Mexico. The estimated annual production of sotol is at around 5,200 hl per year. This industry grows at an average rate of 5% per year. The Mexican Sotol Council and the Sotol Certificate Council are regulatory bodies dedicated to monitoring that sotol producers comply with the Official Mexican Standard NOM-159-SCFI-2004. Currently, those regulatory bodies try to improve the sotol production process and good practice guidelines to contribute to cleaner production. This paper reports a case study of artisanal sotol production in Chihuahua State in Mexico. Life cycle assessment (LCA) technique was used to compute the environmental impact of sotol and its performance to identify system hotspots and propose improvement interventions. SimaPro software, v.9.1®, is used for the LCA, applying CML-IA baseline V3.05/EU25 method to evaluate and select environmental impact categories. The system boundary included the stages of harvest, cooking, milling, fermentation, distillation, bottling, and packaging. The findings indicate that each of the stages required for sotol beverage processing significantly affects the marine ecosystem. The milling and bottling stages have the highest environmental impact. A 750-ml bottle of artisan sotol causes 5.92 kg CO2 eq, based on empirical data. Sotol makers should focus on reducing energy consumption caused by input transportation and equipment for milling.

The manufacturing industry is faced with a challenge to create products with less environmental impact targeting a sustainable society. To cope with this challenge, sustainable design or ecodesign plays one of the most important roles. Manufacturers often use ecodesign checklists that are intended for obtaining eco-labels, such as Eco Mark in Japan, in order to support design improvements of products in terms of environmental consciousness. Eco-label checklists are, however, insufficient to support designing products rationally because the relationships between individual requirements of checklists and environmental impact are undetermined. This paper proposes a method for supporting assessment for ecodesign by developing a weighted checklist from a conventional eco-label checklist. This weighted checklist assesses the environmental performance of a product based on the potential environmental improvement of each requirement, derived by life cycle simulation. Results of a case study involving a digital duplicator indicate that the proposed method successfully clarifies the requirements that should be improved in the present product. When the design improvements are applied, the assessment of the product’s CO2 emissions shows an improvement by 8%.

The Reuse-A-Shoe program and Nike Grind are sustainability initiatives run by Nike to improve their environmental performance through the recycling of worn out shoes and surplus manufacturing materials into various surface materials. However, the positive environmental benefits associated with recycling may be offset by the negative impacts caused by the extensive logistics associated with these programs. This case study provides an overview and breakdown of both Nike and its recycling programs. It addresses the positive and negative environmental impacts of these programs, such as reduced waste to landfill and increased greenhouse gas emissions from increased transportation. The analysis concludes that these programs have limited potential in achieving any significant positive environmental impact and that Nike should investigate alternative models focusing more on biodegradable materials or a closed-loop system where materials are upcycled rather than downcycled, and where both material use and greenhouse gas emissions are considered.

In the on-site rebar delivery system, as the common method of rebar supply in the construction industry, reinforced steel bars are delivered in large batches from supplier's facilities through contractor's warehouse to the construction site. Rebars are then fabricated on-site and installed after assembly. In the new delivery system, called prefabrication Just-In-Time (prefab-JIT) system, the off-site cut and bend along with frequent rebar delivery to the site are applied in order to improve the process and increase its efficiency. The main objective of this paper is to assess and compare the environmental impacts resulting from the air emissions associated with the two rebar delivery systems in a case study construction project. Environmental impact categories of interest include global warming, acidification, eutrophication, and smog formation. A process-based cradle-to-gate life cycle assessment methodology is applied to perform the analysis. The results show that the prefab-JIT rebar delivery system causes less contribution to all mentioned environmental impact categories compared with a traditional on-site delivery system.

Purpose The purpose of this paper is to present a case report involving environmental performance analysis of a big Brazilian graphic company. Design/methodology/approach An “environmental performance indicator” (Iepa) was developed, which is calculated taking into consideration the weighting of potential environmental impact of each residue/sub-product generated, the relative spatial dispersion which each residue/sub-product can reach and adequacy evaluation of final allocation accomplished by the company for each residue/sub-product. Findings Despite the evidence that the corporations emit gases generated by the burning of volatile organic compounds to the atmosphere, the result obtained is favorable to enterprise, largely, due to the adequate allocation given to industrial effluent, which is the waste with the largest share on Iepa (50.2 percent). Industrial effluent is collected by a company licensed by Environmental Sanitation Company of the state of São Paulo, which is an environmentally adequate practice. The result of Iepa=90.8 percent is explained by the large amount of CO2 emitted by the operations into the atmosphere throughout the year. Practical implications The method used can be applied to measure the environmental impact generated by any business of a graphic service sector. Originality/value The authors observed, in the specialized literature, a small number of works dealing with the environmental management of graphic sector companies, as well as methodologies for assessing the environmental performance of companies through environmental performance indicators. The originality of the work is in the developed method, which takes into account: the potential impact of each residue/sub-product generated; the amount of each residue/sub-product generated in a given time period; the dispersion that each residue/sub-product can attain; and the evaluation of eventual allocation of each residue/sub-product.

To get more insight in the environmental performance of the Suiker Unie beet sugar, Blonk Consultants performed a comparative Life Cycle Assessment (LCA) study on beet sugar, cane sugar and glucose syrup. The system boundaries of the sugar life cycle are set from cradle to regional storage at the Dutch market. For this study 8 different scenarios were evaluated. The first scenario is the actual sugar production at Suiker Unie. Scenario 2 until 7 are different cane sugar scenarios (different countries of origin, surplus electricity production and pre-harvest burning of leaves are considered). Scenario 8 concerns the glucose syrup scenario. An important factor in the environmental impact of 1kg of sugar is the sugar yield per ha. Total sugar yield per ha differs from 9t/ha sugar for sugarcane to 15t/ha sugar for sugar beet (in 2017). Main conclusion is that the production of beet sugar at Suiker Unie has in general a lower impact on climate change, fine particulate matter, land use and water consumption, compared to cane sugar production (in Brazil and India) and glucose syrup. The impact of cane sugar production on climate change and water consumption is highly dependent on the country of origin, especially when land use change is taken into account. The environmental impact of sugar production is highly dependent on the co-production of bioenergy, both for beet and cane sugar.
