Trending technologies, no success stories yet.

Potential advantages regarding:– Land use (less competition for marine areas)– Energy for harvesting (“sieves” vs. centrifuges etc.)

However, macroalgae are cultivated partially inlandin raceways or photobioreactors.

• There is a trend towards algae biorefinery concepts with non-fuel products such as neutraceuticals.

• New algae species are explored including macroalgae.

Findings

LCAs on algae: results

Hundreds of specific and valuable results available

• There is a trend towards algae biorefinery concepts with non-fuel products such as neutraceuticals.

• New species are explored including macroalgae.

Enlarge scope of algae based production systems towards all application options and value chains.

• Big potential to mitigate GHG and save fossil resources, though not in all cases.

• Burdens regarding some environmental impacts with patterns similar to those of biofuel LCAs.

Findings

Not all products from algae are associated with environmental benefits nor sustainable – just because they are “bio”.

There is a high potential – far above average –for algae based products being environmentalfriendly.

It is worth to continue investigations and especiallyimprovements of algae based product systems torealize these potentials in future.

Not all bio-products from algae such as bio-energy, bio-chemicals or bio-nutrients are associated with environmental benefits nor sustainable – just because they are “bio”.

There is a high potential – far above average – for algae based products being environmental friendly. Therefore: intensify investigations on algae related projects.

Take home messages

LCA works very well for both, to identify the environ-mental implications and to improve the system or product. It helps to realize these potentials in future.

Need to perform a LCA for each algae based production system investigated to direct science, industry and policy.

Simple solution in some cases:

Don’t promise more than you can deliver.

Life cycle GHG emissions (not „LCA“) LCA (not „environmental assessment“) Cradle to gate / well to tank ≠ life cycle

LCA Journal

LCAs of algae based products: latest highlights

Largely meetingLCA qualitystandards

LCAs of algae based products

More technically adequate LCAs– higher number and higher share

Fewer limitations in insufficient LCAs– e.g. more impacts covered in most publications

Take home message 4.1

Make sure to go for a full comprehensive LCA if you are seriously concerned about the environmental impacts of algae based products. (And add a LC-EIA).

LCAs of algae based products

All publications listed: by far not a LCA !

LCA standards and guidelines should be followed – Unless there is a good reason not to do so– Everything else is just bad practise

LCA is valuable for ex-ante assessment– Limited data particularly requires scenario-based

assessments with sensitivity analyses– It is easy to promise a lot without caring about details

Take home messages 4.2

Don’t jeopardise public trust by empty promises– New promising technologies like algae tend to cause

hypes (including unrealistically positive LCAs)– This is a long term threat for algae and LCA communities– Peer review could sustain quality with suitable experts

Take home message 4.3

Precise questions needed– General purpose accurate descriptions need

data of several years of production at scale– Otherwise, data quality analyses require specific goals

Scenarios on future mature technology – Fair comparison to established technologies– Data extrapolation by experts needed

Data checks and sensitivity analyses – Compare to other sources.– Identify its influence on results and conclusions.

LCA can answer questions despite poor data

?

Take home messages 5 and 6

For a complete identification and optimization, the simultaneous application of both, LCA and LC-EIA, is appropriate, especially if raceways or ponds are involved for algae production.

LCA works very well for both, to identify some environmental implications and to improve the system or product. Need to perform a LCA for each algae based production system investigated to direct science, industry and policy.
