Limbah cat yang tidak mempunyai nilai ekonomis dan memerlukan biaya untuk pengolahannya, dapat dimanfaatkan sebagai bahan baku menjadi produk yang berguna. Limbah cat digunakan sebagai bahan baku campuran pembuatan produk bata beton (paving block) agar dapat mencegah dampak negative lingkungan. Penelitian yang dilakukan bertujuan untuk mengkaji dampak lingkungan dan kesehatan dari limbah cat dan pemanfaatannya sebagai campuran bata beton.  Dampak lingkungan sebagai ekotoksisitas dan dampak kesehatan berupa toksisitas dihitung menggunakan perangkat kajian daur hidup LCA (Life Cycle Assessment) pada variasi kadar limbah cat sebesar 1,2,3,4 dan 5% pada bata beton. Hasil kajian menunjukkan penurunan potensi dampak lingkungan dan kesehatan produk bata beton dibandingkan limbah cat padat. Ekotoksisitas limbah cat terendah pada media tanah dan tertinggi pada media perairan air tawar. Toksisitas pada manusia jauh lebih tinggi dibanding pada media lingkungan, dipakai sebagai dasar penanganan limbah cat. Pemanfaatan limbah cat sebagai bahan baku campuran bata beton dapat mengurangi ekotoksisitas dan toksisitas secara signifikan, dapat digunakan sebagai model pengelolaan limbah. Paint waste that has no economic value and requires a cost for its processing can be used as raw material to become a useful product. Waste paint is used as a raw material for the manufacture of concrete brick products (paving blocks) in order to prevent negative environmental impacts. The research carried out aims to assess the environmental and health impacts of paint waste and its use as a concrete brick mixture. Environmental impacts as ecotoxicity and health impacts in the form of toxicity are calculated using the LCA (Life Cycle Assessment) life cycle assessment tool on the variation of paint waste content of 1,2,3,4 and 5% in concrete bricks. The results of the study show a decrease in the potential environmental and health impacts of concrete brick products compared to solid paint waste. The lowest paint waste ecotoxicity in soil media and highest in freshwater waters media. Toxicity in humans is much higher than in environmental media, used as a basis for handling paint waste. The use of paint waste as raw material for concrete brick mix can significantly reduce the ecotoxicity and toxicity, it can be used as a waste management model.

The objective of this paper is to determine and compare the environmental impacts of two toasters: standard and eco-friendly. The most rapidly growing sector for the e-waste world comes from Electronic household products. More than 2 million tons of electronic products are disposed off as solid waste to landfills in the US alone. The demand for energy supplies has been rapidly increasing in the past decade. Strict legislative measures should be enforced to protect the environment by making industries collect back the manufactured products at the End-of-Life (EOL) from the users and recycle the products. If these necessary steps are not taken, then these e-wastes will impose serious threat to society and the environment. In order to re-design environmentally friendly products and facilitate sustainable take-back planning, current products need to be evaluated for their environmental impacts. One of the widely used methodologies to assess the environmental impacts of a product is called Life Cycle Assessment (LCA). LCA is a cradle to grave approach for assessing the environmental impacts of a product. The cradle to grave approach includes raw material phase, manufacturing and assembly phase, use phase, recovery phase and disposal phase. The system boundary for LCA presented in this paper includes material phase, manufacturing phase, use-phase and disposal phase. The functional unit for the LCA is entire life of the toaster which is one year based on manufacturer’s warranty which also includes the rate of usage. The environmental impacts from the two toasters as presented in this paper include eutrophication, acidification, energy-use and global warming. The use phase energy impact is experimentally determined.

Pavement Construction

The environmental impacts of airport pavement construction were evaluated in this study through a life-cycle analysis approach. Total primary energy (TPE) consumption and greenhouse gas (GHG) emissions from material production and construction of pavement were determined by using life-cycle assessment (LCA), a quantitative methodology described in the ISO 14040 series. A tool was developed to implement a probabilistic LCA through the Monte Carlo method. This tool allowed for consideration of uncertainty from life-cycle inventory data. A case study on the construction of Runway 10R-28L at Chicago O'Hare International Airport focused on mainline and shoulder pavement designs. Environmental impacts from producing materials for the pavements increased from lower to upper layers, while asphalt layers had relatively higher TPE consumption than the upper portland cement concrete layer—and vice versa for GHGs. Impacts from material production overshadowed those from construction, which contributed less than 2% of TPE consumption and GHGs. Further analysis showed that two production processes—for asphalt binder and portland cement—were the leading contributors (45.3% and 29.2%, respectively) of TPE consumption, while the latter was the leading contributor (73.4%) of GHGs. A probabilistic analysis compared the original 10R-28L runway design and a modified design that did not use recycled materials or warm-mix asphalt technology. The results from 1,000 Monte Carlo simulations showed that the environmental impacts from the two cases were statistically significant, with the original design having lower TPE consumption (482 versus 693 MJ/yd2 for TPE) and GHGs (37.5 versus 53.9 kg of carbon dioxide equivalent per square yard).

Colombia is a major flower exporter of a wide variety of species, among which the chrysanthemum plays a major role due to its exporting volume and profitability on the international market. This study examines the major environmental impacts of the chrysanthemum supply chain through a life cycle assessment (LCA). One kg of stems export quality was used as the functional unit (FU). The study examines cut-flowers systems from raw material extraction to final product commercialization for two markets (London and Miami) and analyzes two agroecosystems: one certified system and one uncertified system. The transport phase to London resulted in more significant environmental impacts than the transport phase to Miami, and climate change (GWP100) category was significant in both cities, generating values of 9.10E+00 and 2.51E+00 kg CO2-eq*FU for London and Miami, respectively. Furthermore, when exclusively considering pre-export phases, the uncertified system was found to have a greater impact than the certified system with respect to fertilizer use (certified 1,448E-02 kg*FU, uncertified 2.23E-01 kg*FU) and pesticide use (certified 1.24 E-04 kg*FU, uncertified 2.24E-03 kg*FU). With respect to the crop management, eutrophication (EP) and acidification (AP) processes imposed the greatest level of environmental impact. Strategies that would significantly reduce the environmental impact of this supply chain are considered, including the use of shipping and a 50% reduction in fertilizer use.

Energy Technologies

The increase of greenhouse gases (GHG) generated by the burning of fossil fuels has been recognized as one of the main causes of climate change (CC). Different countries of the world have developed new policies on national energy security directed to the use of renewable energies mainly, ocean energy being one of them. The implementation of ocean energy is increasing worldwide. However, the use of these technologies is not exempt from the generation of potential environmental impacts throughout their life cycle. In this context, life cycle assessment (LCA) is a holistic approach used to evaluate the environmental impacts of a product or system throughout its entire life cycle. LCA studies need to be conducted to foster the development of ocean energy technologies (OET) in sustainable management. In this paper, a systematic review was conducted and 18 LCA studies of OET were analyzed. Most of the LCA studies are focused on wave and tidal energy. CC is the most relevant impact category evaluated, which is generated mostly by raw material extraction, manufacturing stage and shipping operations. Finally, the critical stages of the systems evaluated were identified, together with, the opportunity areas to promote an environmental management for ocean energy developers.

ENGLISHMinimizing the adverse impact of sugarcane plantation can be carried out through many ways including increasing the efficiency of energy and natural resources consumption as well as improving the management of waste and emissions. Life Cycle Assessment (LCA) was applied to assess the environmental impact of sugarcane plantation without considering sugarcane usage as a raw material in the sugar industry (gate to gate). CML (baseline) was used as Life Cycle Impact Assessment (LCIA) method. This study aimed to: 1) examine the natural resources and energy consumption; 2) analyze and identify potential environmental impacts; and 3) recommend alternative improvements to reduce environmental impacts. It used primary data and secondary data. The results showed that: 1) natural resources were used to produce 16,097 ton of sugarcane or 1 ton of sugar, were land requirement (0.233 ha), water consumption (2,223.117 m3), and energy consumption (19,234.254 MJ); 2) there are five most potential environmental impacts which are analyzed by using openLCA including climate change (134,275.23 kg CO2 eq), eutrophication (120.24 kg PO4 eq), acidification (1.54 kg SO2 eq), photochemical oxidation (0.36 kg ethylene eq), and human toxicity (0.15 kg 1.4-dichlorobenzene eq); 3) alternative recommendation could be conducted by reducing the usage of inorganic fertilizer, and utilizing cane trash (dry leaves, green leaves, and tops) as boiler fuel for production process in sugar factory. INDONESIABudidaya tebu menimbulkan dampak negatif terhadap lingkungan sehingga diperlukan upaya untuk meminimalisir dampak negatif tersebut melalui efisiensi konsumsi energi, konsumsi sumber daya alam (SDA), serta pengelolaan limbah dan emisi. LCA merupakan salah satu metode untuk menganalisis dampak lingkungan dari budidaya tebu tanpa mempertimbangkan penggunaan tebu panen sebagai bahan baku industri gula (gate to gate). Metode yang digunakan untuk LCIA adalah CML (baseline). Penelitian ini  bertujuan untuk: 1) menghitung penggunaan SDA dan energy, 2) menganalisis dan mengidentifikasi potensi dampak lingkungan, dan 3) menyajikan rekomendasi perbaikan untuk menurunkan dampak lingkungan. Data penelitian berupa data primer dan data sekunder. Unit fungsional pada penelitian ini adalah produksi 1 ton gula untuk satu tahun. Hasil penelitian menunjukkan bahwa: 1) konsumsi SDA berupa lahan tebu seluas 0,233 ha, air sebanyak 2.223,117 m3 dan energi sebesar 19.234,254 MJ; 2) potensi dampak lingkungan yang dianalisis menggunakan OpenLCA menghasilkan 5 dampak lingkungan tertinggi, yaitu climate change (134.275,23 kg CO2 eq), eutrophication (120,24 kg PO4 eq), acidification (1,54 kg SO2 eq), photochemical oxidation (0,36 kg ethylene eq), and human toxicity (0,15 kg 1,4-dichlorobenzene eq); 3) alternatif perbaikan yang direkomendasikan berupa penggunaan pupuk anorganik dengan dosis yang tepat dan memanfaatkan limbah pasca pane n (daun kering, serasah) sebagai bahan bakar boiler untuk proses produksi industri gula.

Water Assessment

Concrete is the single most widely used material in the world and is only surpassed by water in terms of consumption. By 2013, 4 billion tonnes of Portland cement were produced worldwide, enough to produce about 32 billion tonnes of concrete, which represents more than 4.6 tonnes of concrete per person per year. The high water consumption and large amount of wastewater generated in the concrete industry has become a very important environmental issue. Due to the large global use of concrete, it is essential to correctly assess the environmental impacts of this material including impacts related to water consumption. Life cycle perspective is important because it allows identifying and reducing water related potential environmental impacts associated with products. In concrete life cycle assessment, these impacts are not considered mostly because of lack of data. There are several methodologies for water footprint assessment, as The Water Footprint Assessment Tool and the ISO 14046:2014 standard -that is based on life cycle assessment (ISO 14044)-, as well as sustainable reporting guidelines, which include water assessment for organizations. The aim of this paper is to evaluate existing water footprint methodologies based on life-cycle assessment, their concepts and difficulties, and link them to concrete industry. Out of at least eighteen existing water footprint methodologies, it was found that four of them are feasible for cement based materials industry, however there are differences between the definitions and criteria adopted by each methodology.
