Look beyond the material name

Match the material

HiQLCD search results showing material composition and manufacturing technology

Material, grade & technology

Match the material, product form, grade and manufacturing technology to your model—not just a generic name.

Check the context

HiQLCD dataset information showing boundary, geography, time period and technology

Geography, activity & boundary

Review the region, time represented, production or consumption context, system model and what the boundary already includes.

Review the evidence

References and attachments showing methodology reports, data sources and standards

Documented modelling & review

HiQLCD uses structured modelling, quality checks and professional review, with source and assumption documentation. This is not certification of every record or downstream footprint.

Free fatty acid, vegetable oil

Free Fatty Acid

Unit: kg

Activity Type: Production Mix

3.769e+0

System boundary: Cradle to Gate
Dataset category: Materials
Identity ID: 6bff3989-5d89-41e2-b2a9-ed503021e65c
Associated ID: 002c572e-314c-4778-8ad5-caf7c77df753

Included activities starts: The system boundary of production activities starts from raw material input.
Included activities ends: The system boundary for production activities ends with free fatty acid production.
Description: Free fatty acids are one of the substances produced during the breakdown of neutral fats; this dataset includes primary raw materials, auxiliary materials, energy inputs, and atmospheric emissions associated with the production process, but infrastructure such as production equipment and facility construction is not included within the system boundary of the dataset; the inventory data were sourced from literature and optimized based on the best available information from 2022; the process of producing biodiesel from vegetable oil involves several steps including pretreatment, esterification, neutralization, separation and purification, and distillation, with free fatty acids being a byproduct of this process.
Activity Description: The production process of biodiesel from vegetable oil includes pretreatment, esterification reaction, neutralization, separation and purification, distillation and other steps, with free fatty acids as co-products of this process.
Process Description: Fatty acids are a class of compounds composed of carbon, hydrogen, and oxygen, and are the main components of neutral fats, phospholipids, and glycolipids. Free fatty acids (FFA) are a type of organic acid. Lipids present in the human body can be broadly classified into three types: cholesterol, neutral fats (triglycerides), and phospholipids. Free fatty acids are one of the substances produced by the breakdown of neutral fats.
