Environmental Impact

We are proud that, in the past year, we've successfully reduced our carbon footprint by an impressive 32% – a testament to our commitment to energy conservation and environmental stewardship. Almost 60% of the electricity we use is now generated from sources that produce no harmful emissions. This achievement brings us closer to our ultimate goal of reaching as close to net zero emissions as possible in the coming years.

The switch to LED lamps in our offices and production areas has greatly contributed to our energy savings. These efficient lighting solutions have significantly lowered our electricity consumption, further diminishing our environmental impact.

One of our key initiatives has been the adoption of renewable energy sources. We are excited to unveil plans to install solar panels across our manufacturing facilities. This move not only aligns with our green objectives; it also further helps to make the operations in our industry more sustainable.

Social Engagement


At PST, we believe in the power of giving back and making a difference in the communities we call home. Our commitment extends beyond our core services as we actively engage with local schools and charities, spearheading various projects that aim to enrich lives and foster growth.

Through our partnership with local schools, we've embarked on educational initiatives designed to inspire the next generation. From hosting interactive workshops that ignite young minds with the possibilities of technology and innovation, to offering internships that provide real-world experience, we're dedicated to empowering students with the tools they need for success.

Our collaboration with charities sees us rolling up our sleeves and getting involved in causes that matter. Whether it's participating in charity runs or organizing fundraising events, our team is always eager to contribute their time and skills.

We understand that our responsibilities extend beyond business. By investing in our communities, we're not just giving back; we're building stronger, more vibrant places to live and work. Together, we're making a difference, one project at a time.

We're deeply invested in the health and wellbeing of our employees. We understand that a healthy team is a happy and productive one, which is why we've implemented a range of initiatives designed to support our employees' physical and mental wellness.

To help our team stay fit and active, we offer reduced rates for gym memberships, encouraging everyone to find their strength and stamina outside of work hours. Recognizing the value of camaraderie and teamwork, we also promote participation in sports clubs, fostering a sense of community and shared achievement.

Understanding the importance of balance and mindfulness, we organize regular wellness events and provide dedicated spaces within our company premises for yoga and Pilates lessons. These sessions are designed not only to improve physical health but also to offer a moment of peace and reflection in our employees' busy schedules.

Our commitment to wellbeing is part of our broader ethos of care and support for our team, ensuring that every member feels valued, healthy, and motivated.
