Pfizer’s Commitment to Sustainability: Transforming Waste Management with Harp Renewables’ CX5
Pfizer Inc., a global leader in pharmaceuticals and biotechnology, has always been at the forefront of innovation in the healthcare industry. Known for pioneering medicines such as penicillin, Viagra, and the COVID-19 vaccine, Pfizer is equally committed to sustainability, aiming to make a positive impact on both global health and the environment. With a strong focus on reducing its ecological footprint, Pfizer is working towards carbon neutrality by 2030, investing in renewable energy, and minimizing waste across its operations.
As part of its comprehensive sustainability agenda, Pfizer is tackling food waste head-on by integrating innovative waste management technologies into its operations. Pfizer has recently incorporated the Harp CX5 aerobic food waste processor into both its US and Irish facilities to support their climate action plan and reduce waste sent to landfills. This partnership with Harp Renewables aligns with Pfizer’s mission to improve environmental sustainability while continuing to advance healthcare solutions globally.

The Harp CX5: A Game Changer in Sustainable Waste
The Harp CX5 is an advanced food waste processor that converts up to 5000 liters of organic waste weekly into compost or nutrient-rich fertilizer in under 24 hours. This fully automated system efficiently manages food waste with minimal manual intervention, using advanced sensors to monitor temperature, pH, and moisture for optimal digestion.
Specifications
- Equipment: Harp CX5 with built in bin lifter
- Waste Stream: On-site canteen waste.
- Capacity: 715 Litres/Day, 5000 Litres/Week, 260,000 Litres/Year
- Estimated CO2 Savings: -3227.4 KgCO2eq (- 3.2 Tonnes CO2eq)
By using the CX5, Pfizer is not only reducing the volume of food waste but also contributing to a circular economy. The nutrient-rich fertilizer produced can be used for landscaping at Pfizer’s facilities or donated to local community gardens, providing an eco-friendly alternative to chemical fertilizers. This sustainable waste solution plays a vital role in reducing greenhouse gas emissions, conserving resources, and promoting biodiversity.


Pfizer’s Impact: Sustainable Practices Across the Globe
The Harp CX5 has delivered significant environmental benefits at Pfizer’s US and Irish facilities. Processing 715 liters of food waste per day, it reduces 3.2 tons of CO2 emissions annually, helping Pfizer meet its carbon neutrality goal.
By efficiently breaking down organic waste, the CX5 cuts landfill disposal and lowers waste management costs. These savings are reinvested into further sustainability efforts. The compost produced also enhances soil health, supports biodiversity, and reduces the need for synthetic fertilizers, aligning with Pfizer’s global environmental objectives.

A Greener Future for Pfizer and the Community
Pfizer’s use of the Harp CX5 reflects its commitment to environmental responsibility. By reducing food waste, lowering carbon emissions, and promoting a circular economy, Pfizer is paving the way for a sustainable future.
This initiative also benefits local communities, with the nutrient-rich compost supporting community gardens and sustainable agriculture. Through its partnership with Harp Renewables, Pfizer is advancing its sustainability goals, reducing environmental impact, and setting a benchmark for other companies in the industry.
