We worked with NPK Recovery to design and deliver a bespoke container laboratory to support the next phase of their innovative nutrient recovery process.
The converted container was engineered to operate as a mobile laboratory, allowing synthesis of fertiliser directly at collection sites where permanent facilities aren’t feasible. This project demonstrates how our container conversions can support applied research, sustainability-led innovation, and highly specialised process development in real-world environments.
When a Bristol-based start-up decided to expand its innovative concept of converting human urine into fertiliser, it needed a portable laboratory to begin the next step of its journey. Through close collaboration with our Conversions team, the perfect solution was developed.
NPK Recovery specialises in the recovery of nitrogen (N), phosphorus (P) and potassium (K) from human urine. By capturing these naturally occurring elements from human waste, they can be put to use as a natural fertiliser for the UK agricultural industry. This has the potential to reduce the sector’s dependence on synthetic alternatives to ensure fields have the necessary levels of nitrogen, phosphorus and potassium for high-quality plant growth.
Aiming to optimise removing the naturally occurring nutrients as efficiently as possible, the team at NPK Recovery elected to commission a portable container laboratory to transport between their partner locations. These include sites such as motorway service stations and festivals, where a collection of the commodity is easier, but where having a permanent laboratory is not possible.
When on site, the container will synthesise the waste product into fertiliser, before being transported to farms.
With the first container laboratory set to be the official blueprint to help NPK Recovery define what it needs for future models, the team appointed our container conversion engineers to help them navigate this new process.
After selecting the conversion specialists following a positive recommendation from a fellow customer, NPK Recovery briefed our team to create a bespoke container laboratory. Immediately being assigned a direct contact for the duration of the project, the teams sat down to design the converted unit.
Although critical elements of the laboratory could be decided ahead of installation, aspects such as the location of certain pieces of machinery were unclear. Although this posed a minor issue in designing the internal structure, we were able to advise the NPK Recovery team on critical elements such as the access door placement and ventilation.
With the design finalised and in place, we set out to bring NPK Recovery’s laboratory to life. Selecting a 30-foot unit, our conversion team insulated the structure by installing a new lining and fitting a ventilation system to create a continuous air flow.
Internally, electrical plug sockets were installed to power equipment used by NPK Recovery alongside lighting and storage units.
Externally, an access door and windows on the side of the container were created, and it was painted green so that it would blend better with its surroundings when placed in rural locations. Alongside this, access ports to the urine containers were installed so that they could be easily accessible from within.
The container laboratory was delivered to the NPK Recovery site in Bristol by our trusted haulier. Hoping to be placed within the building, the delivery team were able to transport the unit through a tightly sized entryway to its temporary home. Through skill and determination, they were able to place the container in the desired place without issue.
Our team remained on hand following the delivery of the unit to ensure that the NPK Recovery team were completely satisfied. After a minor issue arose with the sink, the Conversions team were able to resolve the matter within 48 hours.
“Now that we have the unit in hand, we have a blueprint that we can use in the future for our next set of container laboratories. As we start to understand exactly what will be used within the structure, we have discovered minor tweaks and changes, but this was something that the S Jones Conversions team said would happen during the design process.
Overall, we’re thrilled with our container laboratory that will hopefully assist in our journey to creating a natural source of vital nutrients that can help the agricultural industry move away from synthetic alternatives. When we make the jump and commission our next unit, we’ll be returning to S Jones Containers for their help and expertise.”
