Electronic shopping is getting more and more popular, and it is not only clothes and electronics that people buy online, but groceries and household products too. Based on real-life data from a major cosmetics and household products retailer in the Czech Republic, this study set to assess the life cycle environmental impact of parcel delivery. Two archetype parcels containing common household and hygiene products were designed and packed in two distinct ways, and the environmental impact was quantified using the Life Cycle Assessment method. It showed that it is environmentally beneficial to use plastic cushions to insulate the goods instead of paper. However, the most important process contributing to the environmental burden was found to be electricity consumption in the logistics center. Hence, the importance of energy efficiency and efficient space utilization was demonstrated on alternative scenarios. Since the cardboard box the goods are packed in turned out to be another important contributor, an alternative scenario was designed where a reusable plastic crate was used instead. Even though the scenario was based on several simplistic assumptions, it showed a clear potential to be environmentally beneficial. In the study, contribution of other processes was scrutinized, as well as sensitivity to variation of parameters, e.g. transportation distances. The main scientific contribution of this work is to show the importance of logistics and distribution of products to end customers in the rapidly developing field of electronic retail of household products.

In many Asian countries, fired bricksare producedby burning raw bricks in a rudimen-tary clamp kiln without pollution control mechanisms, a practice which contributes to several kinds of environmental impact. This research investigated the inputs and outputs associated with production of fired bricks using the rice husk-fuelled clamp kiln. Data collected includedraw material use, energy, products, emissions and kiln temperatures. To quantify environmental impacts, the consequential-focused life cycle assessment (LCA) approach was adopted. The impactswere assessed in terms of fuel substitution as the acquisition of another fuelwas re-quired to substitute for electricity. The findings indicated that the clamp kiln technology pro-duced lowCO2emissions per unit of production and per unit of energy input, despite poor specific energy consumption. The LCA analysis indicated that the use of rice husk was the major contributor to environmental impact, and that abiotic depletion of fossil fuels repre-sented the environmental hotspot. To improve combustion efficiency, the clamp kilns should beeither insulated or replaced with more efficient kiln technology, in conjunction with the use ofrice husk.

ABSTRACT The primary municipal waste treatment in Tuban Regency, East Java, was landfilling, besides the small amount of the waste was turned to compost. Landfilling causes global warming, which leads to climate change due to CH4 emission. This environmental impact could be worst by the population growth that increases the amount of waste. This study aimed to evaluate the environmental impact on waste management in the Gunung Panggung landfill in Tuban Regency and its alternative scenarios using Life Cycle Assessment (LCA). Four scenarios were used in this study. They are one existing scenario and three alternative scenarios comprising landfilling, composting, and anaerobic digestion. The scope of this study includes waste transportation to waste treatment which is landfilling, composting, and anaerobic digestion (AD). The functional unit of this analysis is per ton per year of treated waste. Environmental impacts selected are global warming potential, acidification potential, and eutrophication potential. The existing waste management in Gunung Panggung landfill showed the higher global warming potential because of the emission of CO2 and cost for human health, which is 6.379.506,17 CO2 eq/year and 5,92 DALY, respectively. Scenario 3 (landfilling, composting, and AD; waste sortation 70%) showed a lower environmental impact than others, but improvements were still needed. Covering compost pile or controlling compost turning frequency was proposed for scenario 3 amendment. Keywords: environmental impact, landfill, life cycle assessment, waste management   ABSTRAK Landfill merupakan pengelolaan sampah utama di tempat pemrosesan akhir (TPA) Gunung Panggung Kabupaten Tuban. Selain landfill, pengomposan diterapkan untuk mengolah sebagian kecil sampahnya. Landfill menghasilkan gas metana yang menyebabkan pemanasan global dan memicu perubahan iklim. Pertambahan penduduk memperbanyak sampah yang perlu diolah di TPA dan dapat memperparah dampak lingkungan yang ditimbulkan. Tujuan penelitian ini adalah menilai dampak lingkungan dari pengelolaan sampah eksisting di TPA Gunung Panggung Kabupaten Tuban Jawa Timur beserta skenario alternatifnya menggunakan Life Cycle Assessment (LCA). Terdapat satu skenario eksisting dan tiga skenario alternatif pengelolaan sampah yaitu landfilling, pengomposan, dan fermentasi anaerob (anaerobic digestion). Ruang lingkup studi meliputi pengangkutan sampah, pengelolaan sampah dengan cara pengomposan, Anaerobic Digestion (AD), dan landfill. Satuan fungsional yang digunakan yakni ton sampah yang diolah per tahun. Dampak lingkungan yang dipelajari di antaranya: pemanasan global, asidifikasi, dan eutrofikasi. Dampak lingkungan skenario eksisting menunjukkan nilai tertinggi terutama pada pemanasan global (6.379.506,17 CO2eq/tahun) dan kerugian pada kesehatan manusia (5,92 DALY). Skenario alternatif 3, yang meliputi pengelolaan secara landfill, pengomposan, dan AD menunjukkan dampak lingkungan yang kecil, namun memerlukan perbaikan. Perbaikan untuk skenario 3 yaitu dengan menambahkan penutup pada tumpukan kompos atau mengontrol frekuensi pembalikan kompos untuk mengurangi emisi NH3. Kata kunci: dampak lingkungan, life cycle assessment, pengelolaan sampah, tempat pemrosesan akhir

Abstract The article presents the activities of selected company - biomass manufacturer and user - with regard to environmental impact of biomass supply chain solutions. The biomass production facility of Biomass User Company is one of the most modern plant in Central Europe. It uses wooden and agricultural biomass to produce heat in biomass-fired steam boiler. The objective of the paper is to investigate the environmental impact with the use of life cycle assessment method. In our study, we define different scenarios for biomass transportation, concerning its supply as well as distribution. Life cycle assessment method is used to estimate environmental impact and to perform sensitivity analysis on transport modes, fuel mix structure and destination of self-cropped biomass. LCA ReCiPe endpoint indicator is used to measure environmental performance. As the results show, transport efforts are not significant factor while environmental impacts are concerned but are rather impact intensive type of activity and should be addressed with company environmental policies.

With the pursuit of embracing the circular economy, having upward trend in vehicle sales and environmental concern, sustainability has become an imperative part of the global automotive manufacturing strategies. One of the tactics to achieve this sustainable goal is to conserve and enhance the resource base by salvaging the embedded values from end-of-life product and for which, the remanufacturing can be considered as one of the most prominent epitome. Even though many of the auto parts like engine, transmissions, starters, alternators and etc. have been assessed for remanufacturability since last few decades, being a major component of a car body the Catalytic Converter (CC) still remains unfocused in literature. However, to examine the remanufacturability of CC, a comprehensive study for assessing its economic, social, and environmental impact is inevitable. Therefore, with an underlying aim of designing the remanufacturable CC, in this endeavour an attempt has made to evaluate the environmental impact of its welding operations by means of energy consumption through gate-to-gate life cycle assessment. Real life data are collected from a Local Malaysian CC manufacturer. The obtained results show that the welding section has a carbon footprint of 0.203 kgCO2e/unit with major emission coming from the plasma arc welding. In addition to that, it is also observed that the value of carbon footprint is not only sensitive to the emission factor and processing time, but also it is responsive to the nature of the processing operations. Certainly, this observation will motivate to change the product design from the prospect of remanufacturing.

Microbial induced carbonate precipitation (MICP) is a new geotechnical engineering technology used to strengthen soils and other materials. Although it is considered to be environmentally friendly, there is a lack of quantitative data and objective evaluation to support conclusions about its environmental impact. In this paper, the energy consumption and carbon emissions of MICP technology are quantitatively analyzed by using the life cycle assessment (LCA) method. The environmental effects of MICP technology are evaluated from the perspectives of resource consumption and environmental impact. The results show that for each tonne of calcium carbonate produced by MICP technology, 1.8 t standard coal is consumed and 3.4 t CO2 is produced, among which 80.4% of the carbon emissions and 96% of the energy consumption come from raw materials. Comparing using MICP with cement, lime, and sintered brick, the current MICP application process consumes less non-renewable resources but has a greater environmental impact. The major environmental impact that MICP has is the production of smoke and ash, with secondary impacts being global warming, photochemical ozone creation, acidification, and eutrophication. In five potential application scenarios of MICP, including concrete, sintered brick, lime mortar, mine cemented backfill, and foundation reinforcement, the carbon emissions of MICP are 3 to 7 times greater than the emissions of traditional technologies. The energy consumption is 15 to 23 times. Based on the energy consumption and carbon emissions characteristics of MICP technology at the current condition, suggestions are given for the future research of MICP.
