Questions related to Environmental Impact Assessment
Hey there,
I am currently conducting a life cycle assessment and as advised, I used different life cycle impact assessment (LCIA) methods to check for robustness of results. I found that when looking at results from climate change at endpoint (ecosystem quality), the values from LC-IMPACT and ReCiPe2016 are similar but IMPACT World+ shows much higher results. SimaPro support mentioned it is most probably due to the different units (species.year and PDF.year vs PDF.m2.year) but I did not find any literature on this topic yet. Would anyone know where to find it?
My main question would be why the value for PDF.year is lower than that of PDF.m2.year. Assuming that the former refers to a global scale because no spatial restrictions are indicated, I would have assumed it would be vice versa with reults from ReCiPe2016 exceeding those of IMPACT World+ (?)
Any ideas or recommendations are much appreciated!
Thanks in advance!
I just made a process simulation of bio-based products from biomass. the process involved pretreatment, hydrolysis, fermentation, separation, biogas production, and CHP (electricity generation). The CHP produced excess electricity where I would like to make a credit simulation of it in Simapro. Anyway, all required electricity has been covered by this excess.
my questions are:
1. should I select the electricity consumption from CHP process in the column of energy?
for example: I make an inventory of pretreatment where it needs the electricity for the pump. So, I select the CHP process in the column of electricity. am I correct?
I face the problem of iteration by doing this
2. how about the excess electricity I have? it must reduce the number of environmental impact
how could I simulate it in simapro to show the credit of having this excess?
Please kindly your advice
Environmental Impact Assessment (EIA) – How is it different from LCA?
In a bustling city, Sarah, a young artist, decides to paint a mural on a blank wall in her neighborhood. The mural depicts scenes of unity, diversity, and hope, intending to inspire a sense of community among the residents. At first glance, it may seem like just another artwork in a city full of vibrant street art, but little does Sarah know that her small action is about to set off a ripple effect that will transform the entire neighborhood.
One morning, a curious journalist named Emma stumbles upon the mural during her daily walk. Intrigued by the beauty and message behind the artwork, Emma decides to write an article about it, hoping to shine a light on the positive impact of public art in urban spaces. The article gains traction quickly and is shared widely across social media platforms, attracting the attention of city officials and community leaders.
Impressed by the impact of Sarah's mural, the city council decides to launch an initiative to promote public art throughout the city. They allocate funds for local artists to create more murals and sculptures in various neighborhoods, aiming to beautify the city and foster a sense of pride and unity among its residents.
As the city becomes an open canvas for creativity, a newfound sense of community emerges. People from diverse backgrounds come together to celebrate the artworks, organizing art walks and community events. Businesses in the neighborhood notice an increase in foot traffic, leading to economic growth in the area.
Inspired by the success of the art initiative, local schools integrate art education into their curriculum, nurturing the creativity of young minds. Sarah's mural becomes a symbol of hope and empowerment, motivating the next generation to pursue their dreams and make a positive impact on their communities.
In an unexpected turn of events, Sarah's mural also catches the eye of a prominent art gallery owner. Impressed by her talent and the impact of her work, the gallery owner offers Sarah an opportunity to showcase her art in a solo exhibition. Sarah's career takes off, and her artwork gains international recognition, drawing attention to the importance of public art in transforming communities.
As the years pass, Sarah's mural stands tall as a symbol of the power of small actions. The once overlooked blank wall has become a landmark, attracting tourists and art enthusiasts from all over the world. The ripple effect of her small action has not only transformed her neighborhood but has also ignited a citywide movement celebrating the role of art in creating positive change.
In this narrative, Sarah's decision to paint a mural exemplifies how a single small action can lead to a chain reaction of positive changes, creating a significant impact on the community, city, and even the art world at large. It showcases the potential power that lies within each individual to make a difference, no matter how small their actions may seem.

Hello everyone,
I am trying to model the process stage (Gate to Gate) of FDM on SimaPro. I understand that I need to decide upon my inputs and outputs as well as system boundary before doing that. I am trying to do this properly and was wondering if anyone can advise more on this methodology (i.e., how to decide upon the values for the raw material input and electricity?, etc...).
Any response is very much appreciated. Thank you.

We are at an era where the technical assessment of processes is digitized. The question that arises is whether in life cycle analysis there are some good practices for digitizing the way in which we assess the environmental indicators through LCA. Excluding the case of buildings, where commercial software already exists (Tally, OneClickLCA) for automatic extraction of life cycle analysis indicators from digital BIM models, are there other cases where the environmental assessment of processes with LCA is done in an automated and digitized way?
In the computer modeling and simulation of floatovoltaic systems in marine environments or freshwater reservoirs, a floating PV photovoltaic array performance model and simulation must characterize the hydrologic impact of floating PV. The same time-series evaporation modelling challenge exists for modeling agrivoltaic PV energy systems. A key aspect is predicting the FSPV or FPV irrigation reservoir water evaporation benefits in the sustainability assessment for sustainable development energy projects. Quantifying evaporative water-saving as a hydrologic impact feature is a crucial project viability metric in a techno-economic model for FPV hydropower hybrid performance models for hydroelectric facilities, or to estimate floating PV array operating temperature or floating PV module internal cell temperature changes in comparative studies for floating FPV and ground-mounted PV or GPV.
Computer estimation of evaporation time-series from a water surface of a water basin or wastewater basin is often calculated in Matlab or Python through mathematical evaporation models, by using parameters such as solar radiation, air temperature, humidity, water temperature, wind velocity, etc. While various applications and modifications of the Penman method, Penman-Monteith equations or Priestley-Taylor evaporation rates are used to predict or determine evapotranspiration rates in various solar water pond cover configurations, and PV floater design types as a sustainability indicator.
However, most water surface modeling or reservoir evaporation methodologies seem to be based on average daily solar irradiation rates, meaning real-time simulation model predictions need to be adapted to account for more instantaneous hour-to-hour solar irradiation data model inputs, ambient temperature variations, wind variations, airmass, relative humidity, water temperature or weather prediction data obtained from remote sensing and weather prediction data.
In a recent publication (link below) on the environmental impact assessment of floating solar PV, we propose a method to time-normalize the hourly predictions of floating solar PV evaporation rates in a water-energy-land-food nexus metric. I would like to know from researchers and scientists if literature is available to discuss other scientific data engineering options for hour-to-hour or even-minute-to-minute evaporation rate estimations on open water surfaces as a means to quantify the evaporation savings of an FPV prototype in a real-time simulation model:

The check dams used as torrent control works have some characteristics - in my opinion - which are neither quite those of retention dams (hydraulic structures) nor quite those of retaining walls. So, taking into account their behavior over their period of existence (50 to 100 years), a short period the check dam works as a hydraulic structure subject of hydrostatic/hydrodynamic pressures. Then, after the upstream sector is completely filled with sediments, it works as retaining wall, perodically submited to floods. I put this question because, verifying such a structure using Eurocode 7 I obtain larger dimensions than using the old global factors of safety. And a more than 100 years of experience shows that economically the last approach is better.
According with the experience and technical regulations in the European countries, are them subject of Eurocode 7 or of some special regulations?
We already know that climate change is leading to a significant increase in sea surface are and reasons are quite obvious. But the question is, how can elevated atmospheric temperature influence underground aquifers? or does it?

I came through to the Canadian climate GCM data download portal (http://www.cccma.ec.gc.ca/data/cgcm4/CanESM2/rcp26/day/atmos/hfls/index.shtml ) in which some ensembles are given. I am not sure which one should be used. I am working on impacts of temperature changes and will be using downscaling techniques.
Are there studies on how various ways of visualizing impact assessments (SEAs or EIAs) affect how the results are percieved? By various ways, I mean for example using set numerical values (-3 <--> +3) or colour gradients (dark red <--> dark green) describing value, impact and consequence as opposed to just plain text.
The results of the concrete experiments can be used to build up a model to determine the power consumption of an equipment and to establish the scale-up method. The Life Cycle Assessment for concrete is an important part of the LCA of buildings. The total life cycle of concrete can be developed in a complex way from the production phase through the usage to the end-of-life stage with the help of information modules of the EPD. For comparative LCAs there is a necessity to analyse, whether there are influences on environmental loads due to scale up. There are effects which should be taken into consideration for such scale-up prognosis in LCA.
Tires are an important part of solid waste in Peru's small-scale ports and fishing villages. I need to make a report about them. But in some years of garbage was not weighed, only images are available. If the tire density (typical) is achieved, it is possible to estimate the weight of the tires of the waste. I have searched in scientific journals without success. I did a test to measure density but I need a published source.
I currently study the possibility of an environmental assessment of viable biowaste management systems for São Paulo, Brazil. The objective of the study is to support policy decision making in a strategic scope. This inevitably led me to a life cycle assessment (LCA). Although, several obstacles led me to consider modelling it in Microsoft Excel:
- Softwires and inventories for life cycle are normally paid, a not viable option to non-funded research in developing countries.
- The objective is to develop a viable framework to municipalities/states with low technical and economic capacity. Excel is a simplified, yet the most viable option to make it accessible for policy making.
- Brazil does not have an extensive and consistent life cycle inventories database yet. Thus, most databases have a huge uncertainty about Brazilian conditions, as these are based on different environmental conditions for emission factors (as example use on land emissions of fertilizers in tropical soil). In this context, inventories in national reports, thesis and other sources present as more convincing sources of data.
- LCA softwires and inventories normally are not as transparent as Excel in allowing several changes in programming code, simulation, etc.
So, is it scientific accurate yet or would it not be considered a LCA as do not follow good practices guidelines (as ILCD)?

Hi. I am trying to help provide some rough advice for selecting amongst alternative sampling designs to measure bird density or abundance. The surveys are short-term in duration such as for impact assessments and habitat association studies. In this instance, I am looking at rough guidelines for how to select where to sample (survey design) and not how to sample (survey method). Attached is a rough first draft of a decision tree (see attachment) to select between various forms of study design ranging from conducting a census to spatially balanced sampling & stratified random designs. Do you have thoughts and suggestions? Is neglecting to include simple random sampling a fatal flaw for example? If so, where would you place it? Of course, the main advice will be to consult with a biostatistician, but hopefully this (with come accompanying text and references) can provide some rough guideance and be a starting point for that conversation. Literature, debate and suggestions welcome and appreciated.
As Allison Aubrey and Dan Charles reported today on Morning Edition, meat has more of an impact on the environment than any other food we eat. That's because livestock require so much more food, water, land, and energy than plants to raise and transport. (Listen to the audio above for their conversation with Morning Edition's Linda Wertheimer.)

While there are increasing support for floating solar panels over water bodies, research on floating photovoltaic power plant assessments in the field of sustainable energy technologies and assessments are studying the negative and positive side effects, including environmental and techno-economic impacts of floating solar panel projects?
The First Global Floating Solar Conference recently stated that: floatovoltaics or floating PV (FPV) preserves agricultural farmland as it reduces the land footprint for ground-mounted solar projects, while the floating solar economic surface transformation (EST) can be defined as the $ income generated from previously unused water surface now tranformed by floating solar to generate income from power and other sources such as agronomic income from saved agricultural land (Prinsloo, 2021).
What are positive impacts of putting floating solar panels over a water body like the ocean or irrigation dams, rivers, canals (including scientific references) ?

Some researchers at Cornell have developed stacked rapid sand filtration technology for use in the developing world. As I understand it, it is useful for doing what traditional rapid sand filtration does, but you can use it in small to medium size municipalities in the developing world where the electrical power required for backwashing is not as available and/or reliable.
We are trying to see how well this technology might work to improve water quality from a nearby river in a rural jungle region of Honduras. It is just an attempt. It may work terribly. I just thought I would see if anyone had any helpful opinions or advice about SRSF and/or its use in various contexts.

Geothermal Energy has long been regarded as Green Energy's silver bullet. And rightly so because of its potential as a stable, secure, environmentally friendly and a cheap Energy resource. But there are some obstacles.
Firstly, Not everyone lives on top of a Volcano! Unlike wind and solar installations which can be built more or less anywhere, Geothermal Power Plants can only be built on geological hotspots that exists less than 10 % of our planet. Secondly, even in hot spots like Iceland, Engineers must deal with the most daunting technical challenge facing geothermal. Drilling! That's because all successful Geothermal ventures require three vital elements. Hot Rock, Water and close proximity to the resource. Thirdly, money and potential exploration risks are additional issues to be dealt with.
Remote Sensing techniques have been aiding in identification of Geothermal Hot spots with thermal anomaly, geological and mineral mapping studies. Geophysical techniques such as resistivity, gravity, seismic and geodetic measurements are valuable in the exploration phase. Next, Geochemical sampling and analysis takes over. RS & GIS are also applicable in Environment Impact Assessments after a Geothermal Power Plant is set up. Recent developments have seen the arrival of Unmanned Aircraft Vehicles (UAVs) for geothermal exploration.
What are the challenges faced by the Geothermal Explorers in different locations such as Indonesia, Kenya, US, Philippines, Japan, Iceland, NZ, Aus., EU and elsewhere. Are there any potential hazards due to their proximity to Volcanic systems.
