**Bachem has announced investment across their site network, with new funding to improve production facilities at their Bubendorf, Vista and St Helens sites, along with a new site in Sisseln.**

Bachem

The expansion plans come in response to the growing demand in peptides and oligonucleotides therapeutics. With the global market for obesity drugs expected to increase by more than 15-fold by 2030, [Bachem](https://www.bachem.com/?ref=pharmamanufacturingiq.com) continues to scale operations in line with rising demand.

#### Stepping up large-scale peptide production with Bubendorf’s ‘Building K’

At its Bubendorf site, Bachem is expanding its large-scale operations with a new production facility known as Building K.

The building incorporates high-capacity production cells for scalable synthesis, advanced energy systems (heating, cooling, water, cold storage, etc.) and a specialised tank farm for large-scale operations.

#### Increased production capacities at Vista site

At their Vista site, Bachem has directed funding to increase annual peptide production capacity to nearly one metric ton.

New features will include:

- Large-scale SPPS reactors for efficient peptide synthesis.
- Cleavage equipment train with two filter dryers to enhance throughput.
- Increased tank farm & waste management to support high-volume operations.
- Automated glass washer & new heating/chilling systems for operational efficiency.

#### Increasing production capabilities for diagnostic peptides at UK site, and plans for new Sisseln site

Improvements to Bachem’s St Helens site infrastructure have resulted in a doubling of output, with a focus on development of research chemicals.

Separately, a new site at Sisseln is being developed in northwestern Switzerland, with concept designs underway.
