Collecting plastic waste on beaches, riverbanks or in communities faces a major problem: Most plastics are not recyclable. However, a number of start-ups are developing innovative concepts to turn the waste into valuable construction materials.

As of today, plastic accounts for 85 % of all marine litter. The United Nations’ Environmental Program (UNEP) estimates that the amount will nearly triple by 2040, adding 23-37 million metric tons of waste into the ocean per year – roughly 50 kg per meter of coastline. The challenge: Only a small fraction of the plastic which is collected from the ocean, beaches, river banks or in municipal landfills is recyclable. PET bottles are, but most composite plastics or plastic waste which degraded over time typically aren’t. 

At the same time, the construction sector is one of the greatest emitters of CO2. A growing number of impact startups are combining the two areas: replacing concrete and other carbon-intense construction materials by new ones made out of ocean plastic and other plastic waste which to date has been classified as “non-recyclable”.

 

Fish'N'Bricks

We are currently supporting a pioneering startup: Fish’N’Bricks – Buildings made from Ocean Plastic for island regions

The spin-off of the KIT University of Karlsruhe, Germany, develops a high-quality, low-tech approach to upcycling low-quality plastic waste into bricks for the construction sector. The target group are small island communities to which this technology provides an attractive alternative to simply burning waste (for energy recovery). The focus is therefore on small-scale production facilities tailored to the specific needs of island states who are struggling with an overflow of plastic waste. The bricks are designed and tested according to German safety and environmental standards. The team is planning their first pilot facility which is to be installed in Indonesia.

Conceptos Plasticos – Vom Abfall zur Unterkunft

The Colombian impact startup builds bricks made of 100 % recycled plastic, which are used to build houses, schools and industrial facilities. The founders are convinced that using plastic as the primary material, you do not only help mitigate the plastic waste problem. Because, on the contrary, you benefit from a better building material which is resistant to bacteria or fungi and which has a remarkable insulating power that minimizes the transmission of energy, heat, and fire. The company started producing their “Bricks & Blocks” in 2020 and have recycled 3000 tons of plastic since then

BioMASON

BioMASON produces bricks using a process that mimics the way coral grows, using microorganisms to produce calcium carbonate that binds sand particles together. The company’s bricks are made without the need for high-temperature kilns, which reduces their carbon footprint.

Eco Raise

Producing bricks from the shells of an invasive species which harms the mangrove forests at the Brazilian North Eastern coastline. It’s a small-scale social enterprise that developed this innovative win-win solution together with a local non-profit.

Paving roads with plastic waste

Turning plastic waste into bricks is just one solution. Other initiatives focus on using residual, non-recyclable municipal or ocean plastic waste for the construction of roads. Two leading companies in this field are from the UK (MacRebur) and the Netherlands (Plastic Road, now renamed in CirculinQ). In Jamshedpur, India, roads were built from a mixture of plastic and bitumen. In Indonesia, roads made of a plastic-asphalt mixture have been built in many areas. The startup GreenTile from Egypt started to produce paving stones from recycled plastic bags. 125 bags make one paving block. As a result, the startup has already been able to recycle 5 million bags. Their goal is to recycle 5 billion by 2025. The need is great: About half of all plastic waste in the Mediterranean Sea is likely to be from Egypt, according to the WWF.

 

The big question is: How to collect plastic waste?

Several companies work on a business model to finance beach, river or ocean cleanups:

Plastic Bank

The Canadian non-profit organization pays locals to collect plastic waste and take it to collection points. The plastic is then recycled and sold to companies like Henkel at a premium that reflects the social benefit that comes with “social plastic.” The program has been very successful and has resulted in the collection of 81,000 tons of plastic. The limitations: The system only works for plastics that have a market value, such as PET bottles.

Plastic Fischer - PREVENT Waste Alliance

Plastic Fischer

The German startup focuses on stopping plastic waste before (!) it enters the sea. It develops floating fences to collect plastic from rivers. As the majority of collected waste is not recyclable, Plastic Fischer started to sell “plastic credits” to companies that want to become “plastic waste neutral.” It is a startup company that installed its first pilot trash boom in 2020. To date, it has already collected about 620 tons of plastic waste.

 The schemes introduced in this article help to expand the opportunities to recycle the so-called “non-recyclable” plastics (which otherwise would have burned to at least recover energy) at a significant scale. There exist other companies which focus on a niche segment, e.g. to produce skateboards, sunglasses or clothes from recycled fishing nets.

Embedding environmental stewardship into IT governance frameworks

Embedding environmental stewardship into IT governance frameworks

Integrating environmental stewardship into IT governance frameworks has become essential as businesses increasingly prioritise sustainability. IT operations contribute significantly to carbon emissions, energy consumption and electronic waste (e-waste). Organisations that embed environmental responsibility into their IT governance can reduce their ecological footprint, improve operational efficiency and strengthen their brand reputation.

Erica Smith, chief alliance officer and environmental, social and governance lead, Blue Connections IT, said, “Environmental stewardship supports financial performance, risk mitigation and brand differentiation. With rising energy costs, increased consumer demand for sustainable products and services, and growing pressure from investors and regulators, companies can no longer afford to overlook their environmental responsibilities.

“Poor sustainability practices in IT can lead to high operational costs, supply chain risks and reputational damage. Conversely, a proactive approach improves efficiency, attracts environmentally conscious customers and helps future-proof businesses against evolving policy and regulatory changes.

“Integrating environmental responsibility into IT governance integrates sustainability initiatives into decision-making systematically. Organisations can reduce waste, lower energy consumption and extend the lifecycle of technology assets while positioning themselves as responsible leaders in an increasingly climate-aware market.”

There are four key areas that present opportunities to embed environmental stewardship into IT governance frameworks.

1. Device lifecycle management

A structured approach to managing the lifecycle of IT assets ensures devices are deployed efficiently, maintained properly and retired responsibly at the end of their useful life. Embracing a circular economy model, where equipment is refurbished, reused or ethically recycled, can significantly reduce e-waste and resource use. Companies that adopt this approach lower their environmental impact and unlock financial value by extending the lifecycle of IT assets.

Smith said, “Effective asset recovery strategies further support sustainability efforts. Integrating secure data erasure and refurbishment into IT governance policies lets businesses repurpose functional devices within the organisation or resell them to external buyers. Responsible e-waste recycling also supports companies to process materials ethically in instances where resale is not viable, reducing landfill contributions and preventing environmental contamination. The adoption of industry-certified data sanitisation methods also safeguards compliance with security and privacy regulations.”

2. Sustainable procurement

IT governance frameworks should prioritise the selection of technology vendors and partners committed to sustainable manufacturing, responsible sourcing and energy-efficient product design. This includes favouring IT hardware with a high percentage of post-consumer recycled materials and using minimal packaging. Additionally, employing Device-as-a-Service (DaaS) models optimises IT asset utilisation while reducing upfront investment and unnecessary hardware purchases.

Partnerships with sustainability-driven IT service providers can further enhance an organisation’s environmental impact. Working with partners that offer end-to-end IT asset management solutions, encompassing secure device deployment, certified data sanitisation and ethical recycling, simplifies the process of aligning IT operations with sustainability goals. Companies that prioritise environmental stewardship in their IT governance framework gain a competitive advantage by demonstrating their commitment to responsible business practices.

3. Energy consumption

Data centres, cloud services and enterprise networks require substantial energy resources, making green IT practices essential. IT governance frameworks should include policies to reduce consumption by optimising server efficiency, reducing redundant infrastructure and using renewable energy sources. Cloud providers with strong sustainability credentials can support carbon reduction initiatives, while virtualisation strategies can consolidate workloads and improve overall energy efficiency.

4. Employee engagement

Educating staff on sustainable IT practices, such as energy-efficient device usage and responsible e-waste disposal, creates a culture of accountability. Organisations that implement green workplace initiatives, such as responsible end-of-life disposal programs, reinforce their commitment to sustainability at all levels.

“IT governance must also align with corporate environmental, social and governance commitments. Companies can contribute to broader sustainability objectives by embedding environmental stewardship into IT policies, such as net-zero emissions targets and responsible supply chain management. Clear reporting mechanisms and regular sustainability audits aid transparency, letting businesses track their progress and demonstrate accountability to stakeholders,” Smith said.

Government regulations and evolving industry standards are increasingly shaping the sustainability expectations for organisations. Aligning IT governance frameworks with best practices for environmental stewardship keeps companies ahead of regulatory requirements. Proactive adoption of sustainable IT practices positions businesses as industry leaders in environmental responsibility.

Smith said, “Integrating environmental stewardship into IT governance frameworks is not just about meeting compliance obligations; it’s about futureproofing company operations and prioritising the broader environment. Taking a proactive approach to sustainability lets organisations drive efficiency, reduce long-term costs and contribute to a healthier planet. Businesses that lead in sustainable IT governance will be well-positioned for long-term success as environmental concerns continue to shape consumer and corporate priorities.”
