Biffa Compost Works (Derby)

Biffa is one of the UK’s largest waste processing companies and specialises in handling and recycling all types of waste and recyclable materials. One of Biffa’s windrow compost facilities is located near Derby. At the facility, an area of concrete hard standing has been established to lay out green waste collected from council and major road work contractors. The purpose of the facility is to compost green waste and produce re-saleable compost for commercial landscapers and other horticultural markets.

The facility was stretched to capacity and costings had been assessed to extend the footprint allowing for double the current capacity. Due to the large cost of some of the modern composting systems and the extensive payback period, Biffa decided to evaluate the effectiveness of an Advetec product on production and profitability.

• Decrease composting time to PAS 100 standard.

• Ensure no PH deviation of finished product.

• Ensure product CO2 discharge was equal to or better than existing.

• Prevent excessive leachate.

A site wide survey was conducted prior to the Advetec dispensing units arrival. During the evaluation period samples were collected and analysis was recorded independently by Biffa. The Advetec 2020 product was dispensed, once weekly for seven weeks, as a fine mist spray from a dispensing unit towed behind a four wheel drive vehicle. The final compost samples were taken from the treated windrow, an adjacent windrow, which had not been treated, and a windrow that had been composting for 18 weeks

In direct comparison with windrows laid at the same time from the same source material.

• The windrow treated with Advetec 2020 product degraded, in compliance with composting standards, within 9 weeks. The control windrow took another 13 weeks to achieve the same quality.

• In comparisons to the windrow that had been degrading for 18 weeks, the trail windrow material was of a much higher standard. The statistics showed a marked improvement in quality.

• In addition, since the facility was limited by physical size it could now receive a higher volume of green waste to process, this would result in an additional net annual revenue of £86.675.

• During the trial it was noticeable that the leachate, from the rows, appeared clearer and no noticeable odour was detected around the treated windrow.

Advetec/NRP Ireland in conjunction with Feed Test Services

Feed Test Services, Antrim, N.Ireland conducted an independent study into the effects of Advetec 900 product on waste effluent within a dairy farm. The aim of the tests was to see if an environmental solution could reduce farm pollution problems in a cost effective manner.

With increasing demands from DEFRA,  resulting from EU Directives, the spotlight within the agriculture industry is firmly on the need to reduce pollution of land, air and water in a cost effective manner.

Mr Johnston’s Dairy Farm is a modern dairy unit with a total herd of 280 cattle housed in 5 main sheds. Each shed has a pit which empties into the main lagoon. This lagoon measures 36 ft (11m) wide x 81ft (24.5m) long x 6ft (1.8m) deep and was where Advetec 900 product was dispensed by a drip feed method. Advetec's dispensing system was installed into the outdoor lagoon system. During the 30-day test period, effluent samples were collected and analysis was performed independently by Feed Test Services Antrim .

Gaymers Cider , Matthew Clark

Gaymers Cider, Mathew Clark, Is one of the UK’s largest manufactures of cider, with a range of well established brands. The company is part of the larger Constellation Group of companies. The manufacturing facilities are located in Shepton Mallett, Somerset and have an efficient effluent system monitored electronically by Wessex Water. The manufacturing facilities are state of the art and comply with latest UK and EU guidelines for the production of drinks for human consumption.

The factory has seasonal increases in solid effluent as a result of annual harvests. This results in peak periods where high COD, TSS and Solids are produced.

• COD

• Suspended Solids

• BOD

• Solids Transported

A site wide survey was conducted prior to the Advetec dispensing system being installed. During the evaluation period effluent samples were collected daily. Analysis was recorded independently by Wessex Water.

During the evaluation period the levels of effluent discharged were monitored and special note was taken of the balancing tank, where 200,000 litres of effluent is stored before it is gradually discharged through the system

Gaymers Cider signed a 24 month contract with Advetec and currently uses a product at 1.2 Litres per 24 hours in the factory, thhis is dosed through 5 dispensers. Gaymers also utilise a single dose unit on the storage tank, this is switched on and off when the tank has been filled for to store excess effluent. Currently, the company has enjoyed a financial saving in excess of £64,000, after costs of Advetec products and services.

Katsouris Fresh Foods

The company is part of the larger Geest Group of companies.
The manufacturing facilities are located around the UK and constantly review their effluent management procedures.
The manufacturing facilities are state of the art and comply with the latest UK and EU guidelines for the production of food for human consumption

In a Group wide drive to reduce effluent levels and costs, Advetec 460 was introduced at the Abbeydale Road factory to evaluate the effects on the existing effluent levels and to prevent the build up of fats at the Queensbury Road Access Point 0502 in the Thames Water main sewer.

During the evaluation period the levels of effluent discharged were monitored and special note was taken of:

• COD

• Suspended Solids

• FOG

A site wide survey was conducted prior to the Advetec dispensing system being installed. During the evaluation period effluent samples were collected weekly. Analysis was performed independently by the Environment Agency Laboratories & Thames Water

Kruger Tissue Industrial Limited

• COD 650 mg/l

• BOD 250 mg/l

• TSS 38 mg/l with daily flow at 3300m³/day.

• COD reduction 650 mg/l to 154 mg/l - 76% Reduction

• BOD reduction 250 mg/l to 66 mg/l - 74% Reduction

• TSS reduction 38 mg/l to 8 mg/l - 79% Reduction

Roberts Food

Roberts Food Group are part of the Greencore Group of companies and are one of the UK’s largest suppliers of frozen yorkshire puddings and desserts.

The state of the art manufacturing facility has seen a steady increase in production over recent years, leading to a rise in effluent discharge. In a group wide drive for IPPC compliance, a 90 day trial of Advetec 460 was initiated at the facility.

• COD

• Suspended Solids

• FOG

• BOG

• Solids Transported

Site drains were inspected and cleaned prior to the Advetec dispensing system being installed. By the end of the 90 day trial, the lines were found to be clear and all traces of odour had been eradicated.
