PT. Sekar Lima Pratama merupakan perusahaan yang bergerak pada bidang tekstil yang memiliki unit usaha finishing kain katun. Dalam identifikasi yang dilakukan perusahaan masih menghasilkan waste dan belum menjalankan proses yang ramah lingkungan. Oleh karena itu diperlukan upaya untuk mengidentifikasi waste pada proses finishing kain tenun guna menjadikan proses yang ramah lingkungan dengan pertimbangan tingkat eco  efficiency dan eco cost guna menentukan proses usulan yang ramah lingkungan. Penelitian ini meliputi langkah-langkah antara lain dengan menganalisa value stream mapping untuk mengetahui kegiatan yang memiliki value added dan yang berkategori NVA. Selanjutnya dilakukan pengukuran dampak lingkungan dengan LCA (Life Cycle Analyisis) serta selanjutnya memberikan usulan memberikan usulan proses dengan pendekatan 6R (reuse, reduce, recycle, remanufacturing, recovery dan redesign) pada proses finishing kain katun diperoleh waste yaitu in appropriate processing, defect dan waiting time. Dari hasil pengukuran Life Cycle Assessment diperoleh hasil untuk proses sebesar 248,76 pt, untuk Life Cycle Impact Assessment Damage Category Human Health sebesar 4,8813 DAILY, Damage Category Ecosystem Quality sebesar 310,000 PDF*m2yr dan untuk Damage Category Resources 1615,646 MJ surplus. Biaya eco cost sebesar Rp 608.425.018,2. Usulan proses ramah lingkungan dengan menaikkan level green manufacturing menjadi recycling dan reuse

Food Production System

Traditional Cambodian food has higher nutrient balances and is environmentally sustainable compared to conventional diets. However, there is a lack of knowledge and evidence on nutrient intake and the environmental greenness of traditional food at different age distributions. The relationship between nutritional intake and environmental impact can be evaluated using carbon dioxide (CO2) emissions from agricultural production based on life cycle assessment (LCA). The objective of this study was to estimate the CO2 equivalent (eq) emissions from the traditional Cambodian diet using LCA, starting at each agricultural production phase. A one-year food consumption scenario with the traditional diet was established. Five breakfast (BF1–5) and seven lunch and dinner (LD1–7) food sets were consumed at the same rate and compared using LCA. The results showed that BF1 and LD2 had the lowest and highest emissions (0.3 Mt CO2 eq/yr and 1.2 Mt CO2 eq/yr, respectively). The food calories, minerals, and vitamins met the recommended dietary allowance. The country’s existing food production system generates CO2 emissions of 9.7 Mt CO2 eq/yr, with the proposed system reducing these by 28.9% to 6.9 Mt CO2 eq/yr. The change in each food item could decrease emissions depending on the type and quantity of the food set, especially meat and milk consumption.

Sustainability Management

Efficient sustainability management requires the use of tools which allow material, technological and construction variants to be quantified, measured or compared. These tools can be used as a powerful marketing aid and as support for the transition to “circular economy”. Life Cycle Assessment (LCA) procedures are also used, aside from other approaches. LCA is a method that evaluates the life cycle of a structure from the point of view of its impact on the environment. Consideration is given also to energy and raw material costs, as well as to environmental impact throughout the life cycle - e.g. due to emissions. The paper focuses on the quantification of sustainability connected with the use of various types of concrete with regard to their resistance to degradation. Sustainability coefficients are determined using information regarding service life and "eco-costs". The aim is to propose a suitable methodology which can simplify decision-making in the design and choice of concrete mixes from a wider perspective, i.e. not only with regard to load-bearing capacity or durability.

As the high demand of energy of the developing countries is met by importing energy and different energy technology, it has become increasingly necessary to discuss the environmental impacts throughout the life cycle of those technologies and make better decisions. Developed in the late 1960s, Life Cycle Assessment (LCA) has become a wide-ranging tool used to determine impacts of products or systems over several environmental and resource issues. The LCA approach has become more prevalent in research, industry and policy with growing concern for the environment. Therefore, the aim of this paper is to introduce the use of LCA in the decision-making process while selecting an energy technology. In this way, more environmentally conscious decisions will be made as LCAs can provide a better basis for this process.
