Facade Mounted Solar Panels

This contractor has installed facade mounted solar panels to supply their temporary site office and reduce the emissions associated with the electricity consumption. Installing solar panels to supply constructions sites has been done before, however, it is incredibly tricky for fit-out projects with limited access to external space to coordinate this. A significant proportion of emissions associated with construction works…


Terrain Aeration

On this project, the existing football pitch, made of heavy clay subsoil, was repurposed as a piling mat for the GSHP array. To improve long-term drainage, they implemented terrain aeration: a 1m hollow probe injected compressed air to create microfractures, followed by milled seaweed. As the seaweed degrades, it leaves organic biomass that keeps the fractures open, allowing surface water…


The Ultimate Cell

This contractor has implemented Ultimate Cell, a hydrogen-based fuel enhancement system, on 15-tonne excavators. The system generates hydrogen through electrolysis and injects it into the air intake of diesel engines, improving combustion efficiency, lowering fuel use, and reducing emissions without requiring engine modifications. Ultimate Cell units were fitted to a 15-tonne excavator, site dumper and telehandler, and monitored over three…


Recycled FabBRICK Panelling

This contractor used FabBRICK which transforms recycled textiles into sustainable wall panels that combine design with performance. Each panel is made from shredded fabrics bonded with an eco-friendly, bio-sourced glue, resulting in a durable and unique material that has natural variations in colour and texture. FabBRICK wall panelling aids with acoustics, provides thermal insulation, and is fire-resistant, while helping to…


The CAGE Hybrid Gas Engine

The CAGE Hybrid Gas Engine (HGE) is a novel generator technology developed and trialled on this construction site. It enables seamless switching between hydrogen, LPG, and (potentially) biomethane fuels, providing a flexible, low-emission alternative to traditional diesel generators. The system is designed for easy integration with site battery storage units and can be optimised for different gas fuels at the…


Murb Transportable Wind Turbine

A rapidly deployable, transportable wind turbine was developed by Murcott Energy, in conjunction with Network Rail and South Rail Systems Alliance (SRSA). This device aims to offer renewable energy to remote railway worksites that otherwise would have typically relied on diesel generators for power. The Murb Wind Turbine is currently being trialled at their site at Old Oak Common. The…


Mushroom Packaging

This contractor is using mushroom packaging which is a sustainable substitute to polystyrene. This eco-friendly alternative provides the same protection while being fully biodegradable, cutting plastic waste and reducing carbon footprint. The product has the following features, it is: biodigestable, biodegradable, hydrophobic, cruelty-free, vegan and it is grown. The technical benefits of the product are it is: vibration tested, edge…


Syntec Fuel

To protect the 80,000 trees that have already been planted and allow them to establish, this contractor installed 6196m of fencing using a Cobalt Plant excavator which runs off Syntec fuel. This type of fuel is a suitable alternative to diesel and HVO, therefore aligning to the projects strategy to deliver using diesel-free construction. The team are also using an…


Carbon Dioxide Absorbing Recycled Aggregate

On this project the contractor began sending concrete demolition waste to London Concrete in 2023 from the marine deck demolition and since the pile cropping’s. The concrete is processed and crushed into aggregate to be used as 20% replacement in new concrete mixes being bought back to site. Taking this one step further they are also using Neustark’s new cutting…


Large Scale Solar Farm Installation

On this project, the contractor installed 136 Solar Panels to the cabin roof at Woolwich by Acute Hoarding for powering the site accommodation. They have used the Enphase App to digitally track energy production and consumption live data. In one month 48% of the site welfare was powered by PV Panels, creating 17,200kWh of energy. This data is published monthly…


Prop Load Monitoring System

The Prop Load Monitoring system is both self-powered and remote controlled, reducing the need for site visits through remote resets and battery status monitoring. The nodes have a long-life lithium ion battery and the data transmission gateway is self-charged via solar panels, so there is no requirement for electrics at site. Upgraded prop load monitoring systems in construction offer significant…


Rechargable Transformer for Temporary Site Electrics

To minimise the use of trailing leads on site, this contractor is using rechargeable transformers across the site for temporary electrics. Operatives can easily transport the lightweight transformers to their workstations for the day. These transformers can take 10,000 recharges in a life time with 1 charge and discharge per day. This product is energy saving, using electricity smarter whilst…


Hydrogen and Electric Mobile Elevating Work Platforms

This contractor is using hydrogen and electric Mobile Elevating Work Platforms (MEWP). This equipment was hired from Speedy and can be charged from mains power, but its battery lasts for the full duration of use without needing hydrogen. As a result, zero emissions were produced during its operation. The MEWP combines the benefits of hydrogen and electric power to create…


Carlton Energy Hydrogen Project

This contractor has entered into a strategic partnership with Carlton Power to supply it with green hydrogen for its manufacturing facility at Stirling, Scotland. The hydrogen will be produced by an electrolyser using electricity that is generated from sources of renewable energy, primarily wind and solar power. The contractor wanted to make the transition from fossil-based fuels to hydrogen in…


Excess Concrete Collection Vessels

Most excess concrete is disposed of in standard waste skips, lined with plastic sheeting. This contractor has developed vessels for collecting concrete that are tailor made for this and will not require using plastic sheeting, which is a waste product in itself. The vessels are also designed to prevent overfilling, which is an industry issue that affects the collection of…
