Analysis of the human health damage and ecosystem quality impact of the palm oil plantation using the life cycle assessment approach

The production of palm oil biodiesel in Indonesia has the potential to negatively impact the environment if not managed properly. Therefore, we conducted a life cycle assessment (LCA) study on the production of palm oil biodiesel to assess the environmental performance in Indonesia. Using an LCA approach, we analyzed the environmental indicators, including the carbon footprint, as well as the harm to human health, ecosystem diversity, and resource availability in palm oil biodiesel production. The functional unit in this study was 1 ton of biodiesel. The life cycle of palm oil biodiesel production consists of three processing units, namely the oil palm plantation, palm oil production, and biodiesel production. The processing unit with the greatest impact on the environment was found to be the oil palm plantation. The environmental benefits, namely the use of phosphate, contributed 62.30% of the 73.40% environmental benefit of the CO2 uptake from the oil palm plantation processing unit. The total human health damage of the life cycle of palm oil biodiesel production was 0.00563 DALY, while the total ecosystem’s diversity damage was 2.69 × 10−5 species·yr. Finally, we concluded that the oil palm plantation processing unit was the primary contributor of the carbon footprint, human health damage, and ecosystem diversity damage, while the biodiesel production processing unit demonstrated the highest damage to resource availability.

Additive manufacturing has emerged as an arena that is receiving intense interest from numerous technology domains, traditional and non-traditional manufacturers. With this growing interest, concerns have arisen regarding the relative performance of these novel processes compared to conventional techniques from economic, environmental, and social perspectives. Sustainability-related benefits can be realized through additive manufacturing, and it is often promoted as a sustainable technology. For appropriate future development and application, however, it will be important to understand relative costs, environmental impacts, and human health effects of processes and materials. Prior research addressing sustainability and additive manufacturing is briefly reviewed. A life cycle assessment is then conducted to understand the environmental performance of a novel additive manufacturing process known as fast mask-image-projection based stereolithography (Fast MIP-SL). In Fast MIP-SL, projection light is patterned by a digital micromirror device as a mask image to selectively cure liquid photopolymer resin, and a two-way movement design is adopted to quickly recoat material. The cradle-to-gate life cycle assessment considers the impacts related to the curing of one resin type and the consumption of electricity in the production of parts of various geometries. Using the ReCiPe 2008 method (hierarchist weighting), it is found that damage to resource availability dominates ecosystems and human health damage types for each part assessed.

In the development of packaging products, the considerations are not limited to the food shelf-life, safety, and practicality, but also environmental sustainability. This paper reports a life cycle assessment (LCA) analysis of a proposed natural fiber-reinforced biopolymer composite takeout food container. The study focuses on the damage assessment of the whole product system, including disposal scenarios of the thermoformed sugar palm fiber (SPF)-reinforced sago starch composite takeout food container. The analysis performed was to anticipate the environmental impact of the cradle-to-grave approach. The results exhibited the total human health damage of 2.63 × 10−5 DALY and ecosystem damage of 9.46 × 10−8 species.year per kg of containers. The main contributor was the carbon dioxide emission from fossil fuel combustion for energy generation that contributed to climate change and caused human health and the ecosystem damages with low-level metrics of 1.3 × 10−5 DALY and 7.39 × 10−8 species.yr per kg of containers, respectively. The most contributed substances in the ‘Particulate matter formation’ impact categories that caused respiratory diseases were from air/nitrogen oxides, air/particulates, <2.5 µm, and air/sulphur dioxide with the metrics of 2.93 × 10−6 DALY, 2.75 × 10−6 DALY, and 1.9 × 10−6 DALY per kg containers, correspondingly. Whereas, for the ‘Agricultural land occupation’, which contributed to ecosystem damage, almost the total contributions came from raw/occupation, forest, intensive with the metric of 1.93 × 10−9 species.yr per kg of containers. Nevertheless, from the results, all impact categories impacted below than 0.0001 DALY for the Human Health damage category and below 0.00001 species.yr for the ecosystem damage category. These results would provide important insights to companies and manufacturers in commercializing the fully biobased takeout food containers.
