What we’re trying to do

Aquaten Clean Green planters (ACGP) take an holistic approach to tackle the multiple aspects of harmful airborne pollution. They have been developed with air-cleansing and aesthetics as their core benefits.

Each ACGP captures noxious gases and particulate matter thereby cleaning 340 cubic meters of air, creating a mini clean air zone where they are positioned, offering the potential for 10 ACG’s to clean 3,400 cubic meters of air for every recharge.

What is the planter (ACGP) made of?

The planters are wooden in construction.

How do you secure the ACGP in situ?

The units are secured to railings or posts where available; or screwed into the floor.

How heavy are the ACGPs?

Approximately 120 kg subject to water content.

How do the ACGPs work ie what pollution do they capture?

The units are a combination of Activated Carbon screens that effectively neutralise a range of airborne pollutants with a double layer of vegetated screens that trap dust particles and remove them from the air.

How does the ivy screen work?

Research conducted by The Green Wall Centre at Staffordshire University provided expertise in the visualisation of particulates on leaves to demonstrate that the ivy screens were capable of capturing air-borne pollutants. In this study, the research team examined leaves for contamination by PM10 to PM1.0.

How does the fabric (activated carbon) work?

Activated carbon works via a process called adsorption, whereby the organic elements of pollutant molecules are trapped inside the pore structure of the carbon substrate. Carbon filtering is commonly used in air purifiers and industrial gas processing. It is also used in a number of other applications, including respirator masks.

How big are the ACGPs?

1.42m wide x 0.65m deep – variable heights from 1.2m up.

Where have the ACGPs been used?

Shaftesbury estate, Soho, London; Wandsworth; Dulwich.

How does the sponsorship work?

AAPCA has numerous interested corporate contacts which have shown interest in supporting air pollution control projects. We match them with appropriate clients. They cover the cost of the units,installation, maintenance and donation to clients.

Click here for proposal.

What is the length of the agreement?

Up to 5 years.

How often do the ACGPs need maintenance?

We advise at least once every three weeks subject to weather conditions and time of year.

Click here for proposal.

What is included in the maintenance?

Cleaning the units, vegetation and sponsorship signs; Re-charging the fabric; wtarering the vegetation where necessary; checking the stability of the units; changing sponsorship where required.

Who installs and maintains the ACGPs?

Aquaten’s team of experienced operatives as part of the agreement.

What is the assessment procedure?

A site visit is made prior to the proposal to assess the most effective area for placement of the units from a point of pollution control, density of traffic and security/safety.

How long will the ACGPs last?

Ten years.

What do the ACGPs cost?

Nil to the site operator.

Why should we be concerned about pollution?

Over the last few years the issue of air pollution has become increasingly prevalent in the media and political circles. Numerous reports quote air pollution as the biggest environmental threat to health in the UK, with between 28,000 and 36,000 deaths a year attributed to long-term exposure. The health of children and the elderly is of particular concern due to higher exposure to air pollution or less resistance. Air pollution reduces lung function and increases the incidence of respiratory symptoms, hospital admissions and motality.

How much pollution does 20 metres of ACGP control?

5kg of noxious gases per week and 3.85 billion PMs per week

What's the difference between adsorption and absorption?

Adsorption and absorption mean quite different things. Absorption is where a liquid is soaked up into something like a sponge, cloth or filter paper. The liquid is completely absorbed into the absorbent material. Adsorption refers to individual molecules, atoms or ions gathering on surfaces.

Who are Aquaten and AAPCA?

AAPCA is a Community Interest Company set up to provide real funding to enable groups and individuals to take positive and effective action to provide solutions and to take measures to protect children and vulnerable people from the harmful effects of polluted air.

Aquaten is a limited company established to develop products to mitigate the impact and effects of flooding and air pollution.


The product recharges naturally, given normal conditions. We also build in a maintenance programme to ensure that ACGP operates at maximum capacity during its life.

Our aim

Clean Green Screen detail

Aquaten has developed a significant tool in the fight against urban pollution, available exclusively from Aquaten Ltd.

Our aim is to provide and achieve:

Clean air zones around areas where vulnerable people congregate;

Improve health, well-being and quality of life for all who may be affected by poor air quality.
