Constraints
- The design must not affect the upstream process
- The design must increase profitability by extracting valuable by-products
- The design must be scalable, and the factory must be feasible to build
- The design must abide by environmental regulations and minimize environmental impact
Criteria
Standards are established by authority and represent an approved method or customary practice. They are necessary to properly guide our decisions, and we will consider these standards in totality throughout our design process, as well in all of our written and verbal communication.

- Terminology and Definitions for Biomass Production, Harvesting and Collecting, Storage, Processing, Conversion and Utilization (ANSI/ASABE S593.1)
- The American Society of Agricultural and Biological Engineers has pertinent information relating to biomass production and processing. This specific standard includes a glossary of vocabulary relating to biomass allowing for our team to communicate, both verbally and in writing, with our advisors using proper terminology (ASABE, 2011).
- Environmental, Health, Safety (EHS) General Guidelines
- The EHS guidelines provide ways to properly manage environmental, health, and safety issues at a facility, project, or design level. They encompass every part of the design process from lab research, product development, implementation, and operations. These standards are important to our design because they encompass both upstream and downstream elements such as raw material input, waste streams, and recycle streams (World Bank Group, 2019). It is critical to our team to consider environmental, health, and safety factors at all stages of our design to minimize risk and environmental impact.
- Standard Test Method for Determination of Total Solids in Biomass (American Society for Testing and Materials, E1756-08)
- This standard comes from the ASTM International Biotechnology Standards, and it elaborates on proper techniques to measure moisture content in a biomass stream or sample (ASTM International, 2021). Since the waste stream is very dilute at the beginning of our process, this standard will be used for early drying unit operations.
- Standard Practice for Evaluating Relative Sustainability Involving Energy or Chemicals from Biomass (ASTM E3066-20)
- This standard provides a method for users to compare and rank options pertaining to biomass processing to analyze environmental and safety concerns. Since our main goal is to extract valuable by-products from an algal waste stream, guidelines like this one that encompass life cycle assessments and sustainable industrial processing practices are very valuable to overall design (ASTM International, 2021).
- Standard Terminology for Industrial Biotechnology (ASTM E3072-19)
- This standard is useful for both written and verbal communication between our DSM and faculty advisors as well as in technical reports like this where proper terminology is critical.
