2024 Collaborative R&D Lead participant

Development of an Innovative Intelligent Multiparameter Fluorometer to Sense the Impact of Organic Pollution on River Health

1 Sep 2024 to 28 Feb 2026

Awarded
£144,984
Total cost £289,968

In a report published by The Rivers Trust (2024) data shows that many of the UK's rivers and lakes are not healthy. Toxic chemicals that remain in ecosystems for decades, pollute every stretch of English rivers to the extent that not a single river in England or Northern Ireland are classified as being in _good overall_ health. Of the rivers failing to ac...

Advancing Digital Precision Aquaculture in China (ADPAC)

1 Apr 2019 to 31 Mar 2022

Awarded
£289,251
Total cost £413,216

This project aims to advance digital precision aquaculture in China towards “Aquaculture 4.0”, which is a highly connected and automated cyber-physical system using digital technologies. Aquaculture production in China reached 45.5m ton in 2014 accounting for more than 60% of the global production. However, this sector in China suffers from the extremely ...

2018 Feasibility Studies Lead participant

Optimisation of imaging fluorometer and food safe tracer for crop spray deposit quantification

1 Jul 2018 to 30 Sep 2019

Awarded
£45,449
Total cost £69,922

"Spray application of agrochemicals is essential to agriculture and it is vital that it is performed accurately and safely yet hitherto spray operators have had no means of rapidly quantifying spray deposits and coverage in the field. In Innovate UK project 101820, which ended on 30 Sept 2017, we developed a new prototype technology that enables spray ope...

2016 BIS-Funded Programmes

Extending the availability and flavour-life of UK apples using innovative photonics

1 Oct 2016 to 30 Sep 2019

Awarded
£37,461
Total cost £83,247

The British apple industry is continuously asked by UK retailers to extend availability; this being achieved by implementing ever more sophisticated storage technologies. Whilst this demand is driven by a brand loyalty to domestic production, the industry is increasingly challenged by imports. In order that primary production of UK apples can be fully uti...

Opportunities for UV Fluorescence monitoring in the Paper Industry

1 Feb 2015 to 31 Jul 2015

Awarded
£5,000
Total cost £5,000

The pulp and paper BREF requires better emissions control and measurement. Daily random or 3 hour composite samples provide data on effluent quality yet real-time measurements are needed to reduce impacts of in-process disturbances on final effluent quality. CTG’s UV fluorescence-based techniques are used in municipal WWTPs to provide real time levels of ...

2014 Collaborative R&D

Hand held imaging fluorometer for measuring and optimising spray deposits

1 Oct 2014 to 30 Sep 2017

Awarded
£181,612
Total cost £307,036

A hand held device that measures spray deposits on crops so that they can be rapidly quantified by spray operators in the field will be developed. This will enable spray operators to determine and optimise sprayer performance e.g. according to crop structure, growth and weather conditions, as well as quality assure spray applications and check for off-tar...

2012 Collaborative R&D

RAPPIDS-Rapid Assay of Pathogens with a Portable Immunosensor for Diagnosing Sepsis

1 Jun 2012 to 28 Feb 2015

Awarded
£61,698
Total cost £154,244

Sepsis is a life threatening condition that arises when the body's response to an infection injures its own tissues & organs.
