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.

The aim of this research was to evaluate the level of greenhouse gas emission from broiler chicken farming industry in Malaysia. In order to achieve that, Life Cycle Assessment method was chosen as a framework to complete the task. A case study was conducted at a broiler chicken farm to gather the data and information related to the broiler chicken production. Cradle-to-gate assessment including distribution stage was conducted based on the ISO14040/1044 guidelines. Inventory data for this case study was gathered in collaboration with one of the selected case study broiler chicken farm company. Greenhouse gas emission that consists of several most affected gases such as carbon dioxide, methane and nitrous oxide was studied. Result shows that the highest carbon dioxide emission came from manure, which accounted for 1,665,342 kg CO2 equivalent per total broilers while the highest methane emission came from feed, which accounted for 126,207.84 g CH4 equivalent per total broilers. For nitrous oxide emission, the highest values came from bedding which accounted for 20,316.87 g N2O equivalent per total broilers in the commercial modern broiler chicken farm. In this case study, it can be concluded that manure gives the most prominent effect to the greenhouse gas emission followed by feed and bedding materials.

The paper is focused on the assessment of the environmental impacts of transport infrastructure and individual types of transport using the life cycle assessment method. The paper contains a description of the basic terminology of the problem related to transport, the environment and methods of environmental impact assessment. The paper contains analysis on monitoring carbon dioxide emissions from a global perspective as well as from a regional perspective focused on Slovakia. The aim of the paper is to create a proposal for the assessment of environmental impacts of transport infrastructure, in the form of specification of areas of assessment for selected types of transport with a focus on carbon dioxide emissions. Using the knowledge and principles of the life cycle method, a proposal for relevant indicators and a proposal for a comprehensive assessment of the impacts of selected types of transport, focused on carbon dioxide emissions, is created in the paper

Goal And Scope

Penggunaan  polimer, koagulan, alum, dan gas klorin pada proses penjernihan air akan mengakibatkan dampak lingkungan. Pendekatan yang dapat digunakan untuk mengidentifikasi dan menganalisa dampak lingkungan adalah dengan metode Life Cycle Assessment (LCA). LCA  terdiri dari empat tahapan utama, yaitu goal and scope, Life Cycle Inventory (LCI), Life Cycle Impact Assessment (LCIA), dan Interpretation. Berdasarkan proses software SimaPro 7 metode Impact 2002+, bagian dalam proses pengolahan air yang menimbulkan dampak lingkungan paling besar adalah penggunaan natural gas. Penggunaan natural gas atau listrik per 1 kg air menyebabkan dampak lingkungan non-renewable energy sebesar 5,55E-9 Pt dan pemanasan global sebesar 4,66E-9 Pt. Penggunaan natural gas yang menyebabkan dampak non-renewable energy adalah ketersediaan gas (6E-9 Pt), minyak (7,66E-10 Pt), dan uranium (3,52E-10 Pt) pada tanah semakin berkurang. Penggunaan natural gas yang menyebabkan dampak pemanasan global adalah carbon dioxide hasil pembakaran bahan bakar fosil (5,46E-9 Pt). Besarnya penggunaan listrik pada proses pengolahan air bersih di IPAM disebabkan jarak pengambilan air cukup jauh dan peralatan yang sudah tua.Kata kunci: air, Instalasi Pengolahan Air Minum, Life Cycle Assessment
