Environmental Sustainability: Definition and Meaning

In today’s world, environmental sustainability has become a central concept, not only for NGOs, international institutions, and governments, but also for companies like ours.
For a company such as Tecnofer, which designs plants for plastic recycling and waste valorisation, sustainability is not an “extra”: it is an integral part of our mission. It represents a commitment to building an economy that respects the environment, today and for future generations.

The idea of sustainability has evolved over time into a broad and structured concept. The current global reference framework is the 2030 Agenda for Sustainable Development, adopted by the United Nations in 2015, which defines 17 goals aimed at ensuring growth and prosperity while balancing environmental protection and social equity.

This approach acknowledges that sustainability cannot be confined to a single area, to be long-lasting, development must be based on three closely interconnected dimensions: economic, social, and environmental.

In the following sections, we will focus on environmental sustainability, aiming to provide as clear and comprehensive an overview as possible.

What is meant by Environmental Sustainability

The modern concept of “sustainable development” was first formulated in 1987 in the report Our Common Future (also known as the Brundtland Report), drafted by the World Commission established by the United Nations. The definition reads as follows: “Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

This definition laid the foundations for a new paradigm: economic growth alone is not enough. Growth must be pursued in a way that does not deplete natural resources or degrade ecosystems, ensuring that future generations retain the same opportunities we have today.

Why Environmental Sustainability is so important today

The current global context makes the adoption of environmentally sustainable practices increasingly urgent. Industrialisation, intensive production and consumption models, widespread use of single-use materials, and unsustainable processes have led to growing environmental challenges: climate change, soil, air and water pollution, biodiversity loss, and waste accumulation.

Plastics, in particular, represent one of the most pressing environmental issues. A large share of the plastic produced worldwide is single-use, and only a small percentage is actually recycled.

This results in severe impacts on the environment, both on land and in marine ecosystems, highlighting the importance of recycling, proper waste management, and reducing the use of non-renewable materials.

For a company like Tecnofer, operating in the recycling technology sector, environmental sustainability is not an abstract concept: it is the foundation of our business. Every plant, every process, and every production choice can make a concrete contribution to reducing environmental impact, enhancing materials that would otherwise become waste, and enabling a truly circular use of resources.

The fundamental principles of Environmental Sustainability

Environmental sustainability is based on a set of principles that guide societies and companies towards a development model capable of respecting the planet’s ecological limits. It is not just about reducing impact, but about rethinking production processes, resource use, and material life cycles from a regenerative perspective.

Below, we explore the main pillars.

Use of renewable energy sources

The transition from fossil fuels to renewable energy sources is one of the cornerstones of environmental sustainability. This principle is based on three key elements:

Reduction of greenhouse gas emissions.

Renewable energy sources such as solar, wind, hydroelectric, and geothermal power do not produce direct CO₂ emissions, unlike oil, coal, and natural gas. According to the United Nations, decarbonising the energy system is the main driver in tackling global warming and achieving the goals of the Paris Agreement.

Energy security and independence from finite resources.

Fossil fuels are inherently limited and often concentrated in geopolitically unstable areas. Renewables ones, on the other hand, come from inexhaustible and widely distributed resources. The shift to clean energy reduces external dependency and supports a more resilient energy system.

Efficiency and long-term cost reduction.

Renewable technologies are becoming increasingly competitive. According to IRENA (International Renewable Energy Agency), over the past decade the cost of solar energy has dropped by more than 80%, making renewables the most cost-effective option in many parts of the world.

Reducing the ecological footprint

The ecological footprint represents the “weight” that human activities place on ecosystems, taking into account:

  • Land consumption
  • Use of water and raw materials
  • CO₂ emissions
  • Waste generation
  • Impact on biodiversity

Reducing the ecological footprint means adopting a holistic approach, including:

  • Resource efficiency: optimising energy and water consumption, reducing waste, recovering materials, and limiting the use of virgin resources. Companies that adopt resource-efficiency strategies gain tangible benefits, including lower costs, reduced exposure to market risks, and a stronger reputation.
  • Sustainable design (eco-design): a product is more sustainable when sustainability is embedded from the design stage: easy to recycle, made from recycled or recyclable materials, durable, repairable, and easy to disassemble. This approach is aligned with the Ecodesign Directive and the new requirements of the European Green Deal.
  • Conservation and regeneration of ecosystems: reducing impact is not enough when ecosystems are already damaged. Regeneration, such as reforestation, soil restoration, and biodiversity protection, will increasingly become an integral part of corporate strategies.

Waste Management: disposal, recycling and valorisation

Sustainable waste management and recycling are among the most critical aspects of environmental sustainability and are closely linked to the circular economy. This principle aims to transform waste into a resource, reducing the need for new raw materials and lowering environmental impacts. In practical terms, it includes three pillars:

Reduction (prevention): The best waste is the waste that is never produced.

This includes:

  • Designing lighter packaging
  • Choosing durable and reusable materials
  • Eliminating over-packaging
  • Digitalising processes

Reuse: reusing a product or component drastically reduces environmental impact by avoiding new production and disposal. This applies to containers, pallets, mechanical components, electronic parts, and more.

Recycling and valorization: recycling and the circular economy make it possible to transform waste into new materials, an essential process, especially for plastics, which would otherwise accumulate in landfills or disperse into the environment.

For Tecnofer, this principle is a strategic asset. The plants developed by our company allow to treat PET, PE, HDPE-PP, and other plastic materials, recovering their value through tailor-made recycling technologies.

Focus on plastics: managing plastic packaging

Plastics are among the most widely used and discussed materials today. Their history includes major achievements, particularly in the medical field, where plastics have been essential to the sector’s development, as well as in automotive and consumer goods. Plastics are essential in many fields, including food packaging and automotive applications.

However, the evolution of their use and the resulting environmental impact require effective and urgent solutions.

In this context, recycling becomes a crucial lever, not only to reduce pollution, but also to recover the economic value of a material that, if properly processed, can be reintroduced into production cycles countless times and used to create a wide range of new products.

Climate change mitigation and adaptation: a cross-cutting principle

Although sometimes considered an objective rather than a principle, this element is so central that it deserves specific mention. Mitigation aims to reduce emissions through targeted actions and strategic choices (clean energy, efficiency, recycling), while adaptation focuses on addressing the effects of climate change already underway, such as heatwaves, floods, and droughts.

The most innovative companies integrate both strategies into their operational decisions.

Environmental sustainability is not the sole responsibility of governments: every actor, companies, institutions, communities, and citizens, plays a role in preserving natural resources.

B2B companies like Tecnofer have a strategic function: they provide technologies that enable entire value chains to improve their environmental performance and make the circular economy model tangible and concrete.

The role of companies and businesses in Environmental Sustainability

Today, companies are among the main drivers of change towards more sustainable production models. Their daily choices and actions determine the real environmental impact: product design, resource management, logistics, procurement, waste disposal strategies, and investments in innovation.

In recent years, the transition towards sustainability has become not only an ethical responsibility, but also a genuine competitive opportunity. According to the Italian Alliance for Sustainable Development (ASviS), companies that adopt responsible policies improve their ability to attract talent, reduce operating costs, gain easier access to capital, and build trust-based relationships with customers and stakeholders.

Sustainable Companies: definition and practices

A company can be defined as sustainable when it integrates environmental, social, and economic objectives into its business model, rather than limiting itself to isolated initiatives. This approach is closely linked to Corporate Social Responsibility (CSR), the voluntary commitment of companies to generate not only profit, but also positive impacts on society and the environment.

Today, these aspects are often summarized within the ESG framework (Environmental, Social, Governance), which evaluates:

  1. Environmental: management of emissions, waste, and natural resources
  2. Social: employee protection, safety, inclusion, and community relations
  3. Governance: transparency, ethics, and responsible management models

Investors and financial markets are placing growing importance on ESG indicators, making sustainable companies increasingly attractive and resilient.

Sustainable Businesses

Sustainable Businesses: how to contribute tangibly to Environmental Sustainability

Companies can adopt a wide range of practices to improve their sustainability performance, reduce environmental impact, and contribute to a more circular economic model. Among the most effective actions are:

  • Improve resource efficiency: reduce waste, optimize energy consumption, and invest in efficiency-enhancing technologies.
  • Use renewable energy sources: install photovoltaic systems, purchase green energy, and implement self-consumption solutions.
  • Implement internal recycling policies: ensure proper waste separation and launch recovery programs for secondary raw materials.
  • Choose sustainable suppliers: integrate environmental criteria into procurement processes and assess the entire supply chain.
  • Promote eco-design: design products that are more durable, easily recyclable, and have a lower environmental impact.
  • Reduce carbon footprint: analyze carbon emissions and define reduction and offsetting plans.
  • Train and raise awareness among employees: sustainability requires expertise and active participation.

A concrete example comes directly from Tecnofer, which supports companies worldwide in improving their sustainability performance through plants and technologies for waste treatment, recycling, and valorization. In the References section of our website, real case studies show how washing plants, depackaging lines, and plastic recovery solutions have enabled customers to transform waste into valuable resources.

Other well-known examples include companies that have transformed their processes by drastically reducing the use of virgin materials, investing in recycled packaging (such as Unilever), or implementing closed-loop internal recycling systems (such as IKEA with wood or PepsiCo with HDPE bottle caps).

Example 1: IKEA

IKEA: a sustainable transformation of the consumption model

Transition to recycled, renewable, and certified materials

IKEA has set the goal of using only recycled or renewable-based plastics in its products by 2030. According to the company’s 2021 sustainability report, more than half of the materials purchased were renewable, with a significant share already recycled. As for wood, one of the core materials in furniture production, around 97-98% is FSC® certified or sourced from recycled wood.

Reducing single-use plastics and packaging

IKEA has phased out non-rechargeable alkaline batteries from its product range, replacing them with rechargeable alternatives to reduce waste and environmental impact. Additionally, by replacing plastic bags with paper bags for accessories and packaging, IKEA expects to reduce the use of virgin plastic by approximately 1,400 tonnes per year.

Circular economy, reuse, and post-consumer recycling

Through its “circular” investment arm (Ingka Investments, part of the group that owns most IKEA stores), the company has announced an investment of approximately €1 billion to strengthen recycling infrastructure in Europe. The aim is to support the transition towards a circular economy, focusing on the recycling of materials such as plastics, mattresses, and textiles, while increasing the global availability of recycled materials.

According to IKEA Italy’s 2024 Sustainability Report, around 94% of waste generated in stores is sent for recycling, and the company has set a target to reach 100% recycled or composted waste by 2030.

Making sustainability accessible

Sustainability is not limited to premium or niche products. IKEA aims to make “sustainable living” accessible to as many people as possible, democratising sustainable furniture in terms of both price and availability.

What companies can learn from IKEA

IKEA’s approach demonstrates that sustainability integration can go hand in hand with high volumes, economies of scale, and an accessible business model. For a company like Tecnofer, operating in recycling and waste valorisation, a similar model, focused on recycling, certified materials, collection and recycling infrastructure, and reuse, represents a strategic direction for promoting the circular economy at an industrial scale.

Example 2: Unilever

Unilever: rethinking packaging and the supply chain

Reducing virgin plastic and increasing recycled content

Unilever has reduced its use of virgin plastic by 18% compared to 2019 and increased recycled plastic to around 22% of its global packaging portfolio.

Reusable and refill models, and design for recycling

Since 2018, Unilever has piloted over 50 reusable or refillable packaging projects across global markets. Some of these initiatives have already been scaled and integrated into the business model, while acknowledging the need for infrastructure and value-chain collaboration.

For rigid plastic packaging, the company aims to make 100% of containers reusable, recyclable, or compostable by 2030; for flexible packaging, the target is set for 2035.

Stimulating recycling and supply-chain collaboration

Unilever goes beyond changing its own packaging by actively stimulating demand for post-consumer recycled (PCR) plastics and supporting the development of a global recycling supply chain. From 2016 to today, the number of PCR suppliers has increased from 2 to over 60.

Key takeaways from Unilever

For companies operating in manufacturing or supply chains, the Unilever case highlights the importance of redesigning packaging, stimulating recycling, and collaborating across the entire value chain.

Environmental Sustainability and technological development

Sustainable technologies are now one of the fundamental pillars for reducing consumption, emissions, and waste. They enable companies to tackle environmental challenges with concrete tools and improve the efficiency of their production processes. Technological evolution, in this sense, goes beyond machines and software, embracing a systemic approach that integrates innovation, data, and circularity.

Advanced tools improve process efficiency and enable tangible sustainability:

  • Energy efficiency: smart sensors, real-time monitoring systems, industrial automation, and high-efficiency motors make it possible to optimize consumption and reduce costs. Heat recovery technologies allow dispersed energy to be reused, creating a virtuous link between sustainability and competitiveness.
  • Advanced recycling: solutions such as hot washing, mechanical and thermal drying, and advanced optical sorting enable the effective treatment of complex plastics. Depackaging technologies, developed by Tecnofer, make it possible to recover materials from packaged products that are no longer marketable, transforming them into new resources and supporting the circular economy.
  • Digitalization and Artificial Intelligence: tools such as digital twins and predictive algorithms help anticipate failures, reduce waste, monitor consumption, and track recycled materials, turning data into concrete actions.
  • Environmental sciences: provide scientific support for responsible business decisions by analyzing ecosystems, carbon flows, air and water quality, and helping to plan targeted interventions to reduce environmental risks.

Thanks to this synergy between technology and scientific knowledge, sustainability becomes a measurable competitive advantage, as well as a commitment to environmental protection.

Challenges and opportunities of Environmental Sustainability

The path towards sustainability is complex and full of challenges, yet it also offers unprecedented economic and social opportunities. Global warming is currently the most urgent threat: according to the IPCC, in order to limit the temperature rise within 1.5°C, global greenhouse gas emissions must be halved by 2030.

The main sources of emissions include energy production, industry, transport, agriculture, and waste management. Reducing them requires an integrated approach combining renewable energy, efficiency, circular economy models, carbon capture technologies, and recycling.

Companies face several difficulties when implementing sustainable strategies. Initial investments can be high, internal skills may be limited, regulations complex, and measuring the real impact of actions is not always straightforward.

Cultural resistance and lack of awareness within organisations can also hinder progress. However, these challenges are not insurmountable: continuous training, strategic partnerships, scalable technologies, and specialized consultancy can enable an effective transition, turning obstacles into growth opportunities.

The benefits of transitioning towards environmental sustainability are numerous:

  • Improving energy efficiency and reducing waste leads to lower operating costs.
  • Sustainable practices open access to new markets linked to recycled materials and green technologies, increasing competitiveness and perceived customer value.
  • Corporate reputation improves, along with attractiveness to investors and talent.
  • Waste valorization becomes a concrete resource: circular processes enable materials to be recovered from unsellable products or production scraps, reducing waste and restoring value to raw materials.

Environmental sustainability is an essential journey to address global challenges and ensure a more balanced future.

Every company can contribute through informed choices, technological innovation, and sustainable materials management. One of the most immediate and concrete starting points is often the most practical one: properly treating waste, enhancing secondary raw materials, and transforming waste into resources by adopting advanced technologies that make it possible to close the loop.
