Life Cycle Analysis of the Raseta Pump Using OpenLCA

Developed and crafted in Madagascar, the Raseta pump is a novel hydraulic ram (hydram) pump using a springs system. It operates differently from other pumps by the exclusive use of water energy due to the water hammer phenomenon induced by the sudden stop of the water flow. The present study initiates the investigation of the environmental impacts of this new type of hydram pump through a life cycle analysis using OpenLCA 1.8. It was found that, when operating in a small-scale water pumping system, the choice of the pump supply pipe material has small differences of environmental impacts, whether the material is made of steel or polyvinyl chloride (PVC). Moreover, compared to a solar pump for the same pumping flow rate, the use of the Raseta pump is more environmentally friendly and less harmful to human health. However, the actual advantageous utilization of such a system needs further studies such as social and techno-economic analysis.

Straw Material: End-of-Life Cycle Analysis Scenario

Bio-based materials end of life is analysed from straw builders and farming practices. This paper proposes a classification of constructive straw systems according to their selective disassembly processes. According to EN 15804 standard, end-of-life (EoL) cycle analysis scenarios are used to create Environmental Product Declarations (EPD). These data will be used: - for architectural projects conception in respect to“RE2020” new French regulation. - as an awareness-raising approach for the long term design of constructive systems.

What is the carbon footprint of primary care practices? A retrospective life-cycle analysis in Switzerland

Background The medical field causes significant environmental impact. Reduction of the primary care practice carbon footprint could contribute to decreasing global carbon emissions. This study aims to quantify the average carbon footprint of a primary care consultation, describe differences between primary care practices (best, worst and average performing) in western Switzerland and identify opportunities for mitigation. Methods We conducted a retrospective carbon footprint analysis of ten private practices over the year 2018. We used life-cycle analysis to estimate carbon emissions of each sector, from manufacture to disposal, expressing results as CO2 equivalents per average consultation and practice. We then modelled an average and theoretical best- case and worst-case practices. Collected data included invoices, medical and furniture inventories, heating and power supply, staff and patient transport, laboratory analyses (in/out-house) waste quantities and management costs. Results An average medical consultation generated 4.8 kg of CO2eq and overall, an average practice produced 30 tons of CO2eq per year, with 45.7% for staff and patient transport and 29.8% for heating. Medical consumables produced 5.5% of CO2eq emissions, while in-house laboratory and X-rays contributed less than 1% each. Emergency analyses requiring courier transport caused 5.8% of all emissions. Support activities generated 82.6% of the total CO2eq. Simulation of best- and worst-case scenarios resulted in a ten-fold variation in CO2eq emissions. Conclusion Optimizing structural and organisational aspects of practice work could have a major impact on the carbon footprint of primary care practices without large-scale changes in medical activities.
