2013
Second site using Portagesters to treat prison kitchen waste now operational. The food waste is digested, composted and screened - resulting in a good quality natural fertiliser and soil conditioner for on site use eg for gardens and within polytunnels.
The financial benefits are in the reduction or elimination of:
- waste disposal charges
- associated security with moving vehicles, bags and skips on and off site
- purchase of compost and fertiliser
Intangible benefits are:
- useful jobs and training within the institution
- control of pollution, odours, vermin and disease risk of food waste
- carbon sequestration and offset

2012
Portagester on trial in the Channel Islands. Many islands around the UK have high waste disposal costs and may need to buy in compost/fertiliser for its farms/horticulture. The Bioplex Process is ideal for local recycling, energy recovery and job creation.
Many islands have their own diesel fuelled generators for electricity generation. These could be converted to combined heat and power, to exchange heat for biogas from a nearby digester. Surplus heat could be used for heating of buildings, greenhouses and amenities.

2012
"Bioplex Process" source segregated food waste digester meets the Animal By-Products Regulations (ABPR). This is the fourth Bioplex plant to comply. It fits neatly into an existing building, which has bunding and water catchment.

September 2009
Local food waste treatment facility under construction, using the patented 3 stage anaerobic digestion and composting.

Summer 2009
PG 1 digester at Center Parc. (Model shown includes additional on-board heater).
The trials showed that a small digester could convert kitchen/food waste within a small area on the site and produce a good fertiliser rich compost for the flower beds and lawns. The trailer can be towed around the resort to various restaurants, food shops and food waste collection bins. After digestion, the Portagester tips out the treated solids onto the composting pad and resumes the collection round. The complete cycle takes two to three days.

Spring 2009
Chris Reynell helps to load a new PG 1 digester with manure at a livery stable. (Model shown includes additional on-board heater).
|
July - August 2008
Roll on-off PG 4 Portagester ® which can be moved and emptied using a standard hook load lorry. One PG 4 can treat 2,500 tonnes per year of food waste whilst producing a slow release natural fertiliser and biogas from the second stage digester.

HM Prisons digester building work complete. HRH The Princess Royal visits the site during the design and construction period.
|
February 2008

November 2007
Testing of one of the three PG 1 digesters built for HM Prisons kitchens. |
June 2007
Picture showing results of the "kitchen top" digester composting trials.
The digested kitchen waste is added to lawn mower clippings in a garden composter, which accelerates the process with less odours and more natural fertiliser as a result. |
March 2007
Start of the development of the "kitchen top" range of digesters. The aim is to provide digesters, small enough to be used at home and in the garden, to produce a nutrient rich natural fertiliser that will accelerate and improve green waste composting e.g. lawn mower clippings. |
January 2007
Otter Rotters produce a natural fertiliser rich compost for use in a nearby commercial nursery.
Although the kitchen waste should be meat excluded, due to the risk of meat in the collected material, the process has been designed to meet the DEFRA's Animal By-Products Regulations (ABPR) standards. |
October 2006
Contruction work completed at Otter Rotters, Honiton, Devon.
Two PG 2 digesters and biogas digester have been installed to treat kitchen waste from 500 homes. |
January 2006
The Longstock Portagester ® is run to produce natural fertiliser compost for selling to local growers. Farm animal and horse stable manure is pasteurised, digested and composted.
|
October 2005
The Portagester ® is an example of an anaerobic digester for DEFRA's Farming without Fossil Fuels project that looks at farming using home grown fuels and other renewable energy sources.
|
January 2005
Project DIPROWASTE complete - results to be published later in 2005.
|
October 2004
Bioplex Ltd is to embark upon the evaluation of a patented low cost conversion of weeping walls, used widely on dairy farms, to an Anaerobic Digestion system. This will, in most cases, produce on-site energy and meet higher environmental standards.
|
September 2004
Reading University Energy Group completes evaluation of a new farm waste treatment system, with production of fertiliser enriched fibre for composting and electricity.
|
August 2004
WRc publishes landfill tax funded study of growing media derived from digested source separated household refuse, hotel, supermarket and catering wastes. Digested, composted and screened fibre makes a good nutrient rich and beneficial organic growing medium.
|
June 2004
A new digester, built by Bioplex Ltd, is now operating in England as a working demonstration model.
|
January 2004
Mid point of EU funded (1.1 million Euro) digester research programme, DIPROWASTE (see www.diprowaste.com) to enhance the digestion process using novel techniques.
