Sustainability
at Towa

Sustainability is one of the pillars that gives meaning to everything we do at Towa International. It is deeply integrated into our Ikigai and guides every decision we make.

Our inspiration: Sanpō-yoshi and Mitsuha

As a Japanese-origin company, we are inspired by the Sanpō-yoshi (三方良し) philosophy, which means “good for the three sides”: every action must generate value for the producer, the receiver, and society as a whole. From this vision comes our sustainability symbol, Mitsuha (三つ葉), meaning “the three leaves” in Japanese. A natural figure representing harmony, health, and growth, symbolizing our ESG strategy and making sustainability a transversal lever of our corporate strategy, structured around the three core ESG pillars:

ENVIRONMENT

Minimizing our environmental impact through the efficient use of energy and resources.

SOCIAL

Protecting the health, equity and well-being of our people.

GOVERNANCE

Assuming responsibility for our activity beyond legal obligations, protecting people’s health.

Our philosophy is to grow in a balanced way that creates value for patients, people, and the environment.

Our environmental commitment

Climate change and energy efficiency

At Towa International, we acknowledge that every activity generates an environmental impact, and we work to reduce it in a tangible and measurable way. We implement a variety of initiatives to improve energy efficiency, reduce carbon emissions, and promote a circular economy. Key initiatives include:

Installation
of new, more efficient GEAs.

Integration of climate-control and process GEA networks.

Improvements in
air-compressor management software.

Optimization of lighting and compressed
air systems.

Our carbon
footprint

Thanks to these actions, in the last fiscal year 2024, we continued advancing in our commitment to reducing our carbon footprint:

We have achieved a 66% reduction in our own emissions (scopes 1 and 2, market based).
And a 23% reduction in our global carbon footprint (scopes 1, 2, and 3) compared to our base year (2019).

Waste management and circular economy

At Towa International, we work every day to minimize our environmental impact and promote circular economy practices across all our operations.

In 2025, we recovered 62.4% of the waste generated at Martorelles through recycling and recirculation initiatives.

We are also members of different associations for waste management. In Spain, we are affiliated with SIGRE for the management of pharmaceutical packaging waste, and with ECOEMBES for parapharmacy product packaging. Through our membership in these schemes, we finance the collection and recycling of the packaging we place on the market in Spain, Portugal and Italy. In Portugal, we are affiliated with Sociedade Ponto Verde. In Italy, we are affiliated with CONAI (Consorzio Nazionale Imballaggi), the national consortium responsible for packaging waste management.

Our Martorelles plant has had a photovoltaic installation since 2015, expanded in 2023, covering most of the available surface of our production plant.

Sustainable mobility

Additionally, we promote sustainable mobility through the full electrification of our commercial fleet in Portugal and providing electric vehicle charging stations at our production plant and office parking facilities in Martorelles, Barcelona. We also offer shuttle bus services for our employees.

we are committed to upholding human rights and decent
labor conditions through clear standards, robust supplier due diligence, ongoing monitoring, and continuous improvement plans.
