Rearrangements:
The most significant gap is pharmaceutical and medical device applications. Alginate wound dressings and algae-derived pharmaceutical excipients fall under Regulation (EU) 2017/745 (MDR) and Directive 2001/83/EC (medicinal products), which are entirely separate regulatory worlds from food or cosmetics. Similarly, pharmaceutical-grade omega-3s (Lovaza/icosapent ethyl) come under a different authorization pathway. This doesn't need to be a full chapter, but even a short stub that orients producers hitting that boundary would be valuable — it's a common point of confusion between “food supplement” and “medicine” status.
Plant protection products is a related gap. Algae extracts used as crop inputs can fall under Regulation (EC) No 1107/2009 (PPPR) rather than the Fertilising Products Regulation, depending on the claimed function. The PPPR has fundamentally different authorization requirements from the FPR biostimulant route. The fertiliser chapter implicitly touches on this but doesn't name it, and producers wanting to make pest-control claims on an algae extract will be completely unprepared.
Biocides (Regulation EU 528/2012) are mentioned in passing in REACH but not named. Algae-derived preservatives in cosmetics and industrial water treatment biocides are a real application area.
Organic certification (Ch. 12) and EU Quality Schemes (Ch. 23) are conceptually neighbours — both are about voluntary standards layered on top of mandatory compliance — but they sit 11 chapters apart. Moving quality schemes closer to Ch. 12 would help readers who approach the wiki from a “how do I certify my product” angle.
GMO (Ch. 22) comes very late. For a producer deciding at the start whether to use GM strains, this is a foundational question that shapes everything. It probably belongs closer to the production chapters (3–5).
Internal to the Food section, the “Meat-related terms” item (Ch. 6.10) reads like an editorial note left in rather than a chapter. The provision belongs in Labelling (Ch. 6.4) with a note on the provisional agreement status.
Production/Hygiene (Ch. 5) and Food Quality and Safety (Ch. 6.1) have a fuzzy boundary — HACCP is in Ch. 5, but the microbiological criteria that define what HACCP is designed to prevent are in Ch. 6.1. This isn't necessarily wrong but users may not find what they're looking for if they go to only one of them.
Specialised Sources (Ch. 27) will become redundant once the new bibliography page is live — they serve the same function. Worth thinking about whether to replace 27 with the new page, or fold the new page into 27.
Two pages apparently referenced but not confirmed to exist: algae:reading_guides (mentioned in the intro) and algae:faq (Ch. 29). If those don't exist yet they should probably be removed from the start page or marked as “forthcoming” to avoid broken links.
Textiles (Ch. 10) and Detergents (Ch. 9) are both fairly thin application areas for algae. They could plausibly be merged into a single “Other Industrial Applications” chapter, which would also make room for a short biocides section.

1. Split “Aquaculture, Agriculture” into two separate chapters These are governed by quite different regulatory frameworks. Aquaculture is under the Common Fisheries Policy and related acts; agriculture is under the Common Agricultural Policy. Keeping them together may confuse users looking for one or the other. Suggested:
2. Add a chapter on “Production & Processing — general”
Before diving into end-use topics, there is a horizontal layer of regulation covering production, hygiene, processing and traceability that applies regardless of the downstream use. This includes the General Food Law (Regulation (EC) No 178/2002), the Hygiene Package, and HACCP. This would be a natural bridge between “Aquaculture/Agriculture” and “Food”.
3. “Home and personal care applications, cosmetics” — separating cosmetics from home care
Cosmetics are regulated by the dedicated Cosmetics Regulation (EC) No 1223/2009 with specific INCI listings and COSING database. Home care (detergents, cleaning products) is a separate regulatory domain.
4. Household products, (Chemical products) (new)
5. “Water use and permits” as a distinct topic within “Spatial planning & permits, water”
Water use permits (abstraction licences, discharge permits) are often the first regulatory hurdle for algae cultivation facilities. The Water Framework Directive (2000/60/EC) and national water law deserve a dedicated section.
6. “Waste, wastewater, end-of-waste” — adding “circular economy” or “nutrient recovery”
Bioremediation with algae sits at the intersection of wastewater treatment and nutrient recovery (phosphorus, nitrogen). The EU Fertilising Products Regulation (2019/1009) interacts directly with this. A mention of “nutrient recovery” in this chapter title or scope will help users who come from the bioremediation/circular economy.
7. “Animal by-products” — clarify scope for algae users
This chapter is important because algae grown on organic substrates (digestate, manure, wastewater) may be classified as animal by-products or derived products under Regulation (EC) No 1069/2009. This is a common compliance issue in bioremediation projects. Flag this connection clearly in the introduction page.
8. Add “Customs classification and trade” The Combined Nomenclature (CN) classification of algae and algal products has significant commercial and regulatory implications (tariffs, import conditions, labelling requirements on import). A short but useful chapter, maybe a sectionwithin “Purpose, Scope, Sources”.
9. “European Quality Trademark” — consider renaming or expanding Refer to the EU quality logos (PDO, PGI, TSG) or the EU organic logo. Consider renaming to Quality schemes and geographical indications. Logicall Organic certification would fall with this topic.
10. Adding “Intellectual property and trade secrets” Patent protection, plant variety rights, and trade secrets are relevant for algae strain developers and biorefinery process owners. This could be a short chapter or a section under “Specialized sources”.
