Harvesting for the Future

We align ourselves with the UN’s Sustainable Development Goals with the aim of having a better impact on the local communities and economies of the countries we operate in.

To ensure that we have a global strategy that is in alignment with other global entities and truly impactful, we use the UN’s Sustainable Development Goals (SDGs) as the base for our strategy. Every and any action that we develop is associated to one, or more, of the UN’s SDGs.

At Cork Supply we understand that Operations management plays an important role in delivering positive results. In 2012 Cork Supply initiated a LEAN Roadmap towards Operational Excellence. This Long-term thinking is transforming the organization into a LEAN company focused on the principles of respect for people and society, continuous improvement, and process improvement.

Harvesting for the Future – 3P Strategy

As a company with a global scale we have an even larger responsibility to care for the future.

Today, in everything that we do, we are focused on being better in these core areas where we can have a more significant impact.



Cork Supply controls vertically integrated operations, from Forest to Bottle, to ensure that its cork closures are of the best quality. Our specialized team of forestry professionals in Portugal work with producers from the main cork oak forest regions in both Portugal and Spain, implementing advanced forest management programs and selecting the best quality raw material for their corks.

We are strongly committed to the use of resources more efficiently, thus minimizing the environmental impacts of our activity reducing our emissions. We have a daily focus on :

  • Minimizing the environmental impacts of our activities - the mitigation and adaptation to climate changes, the protection of biodiversity and ecosystems and pollution prevention.
  • Fostering a sustainable management of the value chain, which implies the sustainable use of resources.
  • Assessing the possibility of implementing environmental improvements, whenever there are changes in processes, people, and products.

Natural Carbon Sinks

“Cork Supply promotes, enhances and enables forests that are important natural CO2 sinks"

As a leading supplier of natural cork, we want our customers and consumers to have complete assurance that natural corks supplied by Cork Supply are sustainably and ethically sourced. We consider our proactive role in this area especially necessary because, as the WWF verifies, montado cork forests:

  • support one of the world's highest levels of forest biodiversity, including the highest diversity of plants found anywhere the world.
  • offer irreplaceable sanctuary to millions of wintering birds, and vital habitat for a native wildlife population that includes several highly endangered bird and animal species.
  • provide an essential, sustainable income source that supports local industry, traditional cultures, and family livelihoods.
  • function as massive carbon sinks, naturally sequestering and providing critical long-term storage for the dangerous atmospheric carbon greenhouse gasses (GHG) that impact climate change.
  • play a key role in critical ecological processes, including water retention, fire prevention and soil conservation.
  • defend European landscapes against creeping desertification and consequent depopulation, poverty and loss of vital ecological biodiversity.
  • are one of the best examples of balanced conservation and development anywhere in the world.

Sustainable Forestry

“Cork Supply was a pioneer in the development of rehabilitation plans of producers’ estates to promote cork oak quality and combat pests and diseases.”


Cork Supply is aware of the importance of preservation of cork oak forests. Not directly owning cork forests, Cork Supply maintains close and strategic relationship with cork forest owners in Portugal and Spain, building lasting partnerships based on trust, shared knowledge, and quality.

We consider it an essential part of our mission to ensure we meet our generation's needs today in a manner that does not compromise our future generations' ability to meet their needs tomorrow.

Cork Supply is aware of the importance of environmental preservation and commitment to minimize the company footprint. The team continually assesses and improves their environmental practices, so they address both inbound and outbound impacts.

Zero Waste & New Energy Sources

“Zero waste is one of Cork Supply’s sustainability goals.“


Cork Supply has set zero waste as one of our sustainability goals and is proactive in seeking to eliminate and reuse the by-products resulting from our operations. In addition to making energy-efficiency and waste-reducing improvements and investments throughout our operations, we seek to reuse and recycle wherever possible.

Targeting our two main production inputs — corkwood and water — Cork Supply has developed closed-loop systems to optimize material and energy waste in both cases.

Today, virtually 100% of harvested corkwood can be reutilized. Therefore, at every stage from the forest onward, Cork Supply has developed closed-loop systems to capture all excess and sub-grade corkwood by-products. Cork Supply has installed a centralized vacuum system throughout our production facilities to capture this cork dust before it reaches the air. This also creates a cleaner, healthier work environment. We have begun to substitute the use of natural gas and electricity by biomass. The result of this is 535,6 ton of CO2eq p/year that are not released into the atmosphere

Montado Living Lab

A living lab to study the regeneration of Montado in the Alentejo.

Cork Supply is proud to be part of the Montado Living-Lab initiative, a project dedicated to regenerating the Montado ecosystem in Alentejo and managing soil health. From an environmental perspective, the Montado region is a vital source of high-quality food, fiber, and various ecosystem services, including carbon sequestration, water storage, soil erosion prevention, fire protection, biodiversity conservation, and habitat for pollinators. On the economic front, the Montado plays a significant role in preventing rural migration to urban areas and is a substantial contributor to the Portuguese economy, with cork exports amounting to billions.

Consortiums like Montado Living-Lab aim to achieve this by fostering enduring partnerships based on trust and transparency. These partnerships bring together key stakeholders, including farmers, multidisciplinary research teams, government institutions, and industry representatives like Cork Supply. The ultimate goal is to improve Montado soil health, restore tree cover, and create more resilient business models for both farmers and industries.

Decarbonizing our Activity

Energy reduction and transition to renewable sources


In order to reduce our greenhouse gase emissions, we employ two key measures with direct impact. Firstly, we prioritize the reduction of energy consumption by conducting energy audits to identify critical areas of intervention with a particular focus on energy efficiency. Secondly, we actively invest in a transition to renewable energy sources by producing renewable electricity in our facilities.


Cork Supply has installed a high-efficiency corkwood boiler system that optimizes both heat energy and water usage. After each batch of corkwood is boiled, heated wastewater gravitates to a holding tank, where a heat exchanger transfers the heat energy from the wastewater to a new batch of clean water. Water use is simultaneously maximized via continuous high-pressure filtration and recycling of boiling water through a steam condensation collection and purging system that prevents cross-contamination between batches.


With the goal of minimizing our contribution to Climate Change, Cork Supply has defined numerous action plans and targets with respect to energy reduction : - 18% energy reduction by 2024 in the technical cork production unit. - 5% energy reduction by 2026 in the natural cork production plant. - Renewable energy alternatives in place at the technical cork production unit by 2023. - The use of cork dust as a source of energy by 2023.
