Key Takeaways:
- Batch systems suit small-scale use; continuous systems maximize throughput and space.
- System design must match BSL levels, with higher tiers requiring monitoring and containment.
- Continuous systems run hotter (150–165°C) for 3–10 sec, cutting utility use and boosting efficiency.
- Solid-laden waste requires pre-treatment to prevent process issues and excessive maintenance.
- Equipment must use Geobacillus stearothermophilus BIs and be built to avoid leaks and cross-contamination.
