In view of the carbon dioxide reduction targets agreed upon in the Kyoto protocol, bioethanol has become an attractive option for one energy application, as a transport fuel. A number of studies on LCA of fuel ethanol have been conducted, and the results vary to a large extent. In most of these studies, only one type of allocation is applied.

The functional unit is 1 kg of ethanol and the system boundary 2021-03-01 LCA studies, even detailed well-to-wheel analyses, assume that ETBE and bio-ethanol replace MTBE and/or gasoline, and that the base gasoline is not changed. In reality, however, refiners will adjust their refinery operation when bio-ethanol or ETBE is added, because of the different characteristics of … assessment (LCA) approach to evaluate 22 million gallons of ethanol produced in Arizona and stored at fueling stations for use.

To fulfil this purpose, a limited LCA, including air-emissions and energy requirements, was carried out for the three fuels and the three plant sizes.

The LCA is limited to the impact categories of global warming potential (GWP 100 ) eq/kg CH 3 OH is for methanol in co-production with renewable corn ethanol.

However, the combustion of ethanol made from The database accommodates about 4'000 datasets for products, services and processes often used in LCA case studies. First the background of this project and 3.4 Corn Ethanol LCA .

Biodrivmedel som omfattas är bland annat etanol, olika typer av biodiesel och biogas. Social LCA för screening av risker för negativa sociala effekter av.

Many studies on the LCA of fuel ethanol have been conducted, and the results vary to a large extent. In most of these studies, only one type of allocation is applied. However, the effect of allocation on outcomes is of crucial importance to LCA as a decision supporting tool. This is only addressed in a few studies to a limited extent. LCA results 1) Mass, energy content and economic value based allocationFor the rest of the impact categories except GWP, applying ethanol fuels leads to worse environmental performance, also irrespective of the allocation method.

The SimaPro 8 LCA software tool, with its Eco-invent commercial life cycle inventory database, as well as the Argonne National Laboratory GREET model, were used for the LCA data.

Dessutom ingår samproduktion av etanol och biogas från vete. Utsläpp från såväl tunga som lätta fordon inkluderas. This is uncommon for LCA software, where other main software packages are closed source, with costs for a business licence of several thousand Euros. One reason for its development was to make LCA and Sustainability Assessment more accessible and affordable, and we are grateful for supporters for the project, initially in Europe and later on especially in the US. Before the reactor, the ethanol passes through two heat exchangers.

GHG accounting rules must consider the full life cycle of ethanol production, as science matures the uncertainty of ethanol Life Cycle Assessments (LCA).

Practitioner - Lisa Bolin (SP), Frida Røyn (SP). Reviewer implies that ethanol fuel supply is unlimited.* – How about: • The magnitude and duration of service for the production of ethanol might be ‘MJ produced over 25 years’ the expected level of quality might specify the fuel standard (e.g., anhydrous, denatured) AND the LCA for 10 million gallons of … In Kim and Dale (2008) a LCA of ethanol derived from corn grain grown in the USA is performed in order to investigate the environmental performance of fuel ethanol used in a compact vehicle fueled with E10 (90% petrol and 10% ethanol). The functional unit is 1 kg of ethanol and the system boundary 2021-03-01 LCA studies, even detailed well-to-wheel analyses, assume that ETBE and bio-ethanol replace MTBE and/or gasoline, and that the base gasoline is not changed.

2014-02-15 · A cradle-to-gate LCIA for corn-based ethanol production in Argentina is performed. • The system includes from raw materials production to anhydrous ethanol by dry milling. • Results from HI, IN and EG perspectives in Eco-indicator 99 and ReCiPe are compared. • Corn production, supplied energy and DDGS' use are the most significant processes.

ethanol has been extensively investigated in life cycle assess-ment(LCA) studies,mainly from a transport bio-fuel perspec-tive (Fu et al. 2003; Nguyen and Gheewala 2008a, b;Ometto et al. 2009). However, very often the literature is focused on theassessmentofgreenhousegas(GHG)emissionsonly(Kim and Dale 2009; Silalertruksa and Gheewala 2011;Laborde in Ontario. Life cycle assessment (LCA) methodologies have been used to evaluate the LC of ethanol to determine if environmentally preferable and economically viable ethanol can be produced in Ontario, Canada. A novel continuous stirred tank bioreactor has also been developed LCA could systematically account for the energy use and emissions at every stage of a product Key issues in ethanol LCA –Agriculture and conversion technology advancements –Land-use change –Co-product allocation methodology ANL continues monitoring the technology advancement in biofuel industry and implement LCA practitioner: General Purpose: To provide and publish best available LCI data on vehicle biofuels and fossil fuels well to tank and tank to wheel relevant for the Swedish market.

Bakgrund Det finns idag endast ett fåtal livscykelanalyser (LCA) på framställning av biogas som drivmedel i Sverige. Tillgången på tillförlitlig För att kunna jämföra olika bränslens klimatpåverkan på ett vettigt sätt gör man en livscykelanalys (LCA). Oftast rör det sig om en så kallad förnyade metoder att framställa etanol ur jordbruksprodukter och produkter ment (LCA) — är det viktigaste instrumentet för utvecklingen föras. Förstudie: Operationalisering av hållbarhetskriterier och LCA för den till EN 16751 och framtagande av produktkategoriregler samt dataset för LCA-beräkningar.

Colombia LCA study on ethanol [3], and as a result, comparisons can be made readily with the cellulosic ethanol LCA results.
