Bioplex News for 2016
Introducing Portagester Systems
Portagester Systems Ltd is a newly formed company to:
- Commercially exploit the patented "Bioplex Process" of two, three and four stage hybrid anaerobic digestion and composting.
- Install Biolectric farm digesters, plus gaining planning permission and grid connections for Solcap Energy Ltd (www.solcapenergy.co.uk).
- Anaerobic Digester upgrades. For example, by adding extra digestion stages to conventional AD plant to increase biogas (and energy) outputs from the same amount of feedstock and to improve reliability by significantly reducing the grit problem that often causes digester failure within 2 to 5 years.
- The UK and Ireland partner of Snow Leopard Projects (en.snow-leopard-projects.com). These range from 250 kW to 2 MW (and larger) biogas plant, some have been running for over 10 years. We share a common anaerobic digestion process, see Bioplex News - January 2004!
- Specialising in anaerobic digesters for "family sized" farms, eg 120 cows and several hundred acres. The current development is in uses of digestate eg natural slow release fertiliser, fibre for solid fuel or bedding, energy storage. The whole AD plant can be mobile and modular.

25 & 50kW AD Plant
A new company to supply this small, yet important scale of anaerobic digesters will be announced later in 2015.
New Licensing in Progress
Licensing and technology exchange and licence for use of the Bioplex Process, in medium to large digesters, in countries bordering the Mediterranean Sea. Licence for Portugal starting in July 2015. (www.saigas.com)
Several digesters using the Bioplex Process produce biogas with methane content in excess of 70%, thatís more energy from less gas.Back to Top
Bioplex News for 2014
Winter is coming!
Trials using solid fuel made from the screened and dried digested solids. There is little or no nutrients in the fuel, these nutrients can be spread onto fields and gardens in liquid or solid form as a natural slow release fertiliser.
Second digester passes 5-year milestone
A second food waste treatment plant, built in 2009, whose biogas (final stage) digester has not had problems with grit and debris build up problems that can occur with conventional AD plant.
Note that digester vessels are transportable, with pipes and electrical connections plugged in.
The UK's first three stage AD plant
The reception and first stage digester under construction. The Bioplex process is used in this 125 kW AD plant and will use a mixture of farm animal and horse stable manures and home grown energy crops, under rotation.
Digester passes 5-year milestone
A Bioplex AD plant which treats food waste in accordance with Animal By-Products Regulations has now been in successful use for 5 years. This digester vessel originated from an earlier trial on the same site and is still working well.Back to Top

Bioplex EU Expansion
Technology exchange and licence agreement for a manufacturing company to use the Bioplex Process in an EU country.
Kitchen Waste Portagester Operational
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

Channel Islands Trial
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.
Fourth Plant to gain ABPR Compliance
"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.Back to Top
Bioplex News for 2009
Local food waste treatment facility under construction, using the patented 3 stage anaerobic digestion and composting.
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.

July - August '08
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.
July - August '08
The Royal Welsh and Pembrokeshire Shows. The PG 3 Portagester ® can treat up to 7 tonnes per batch every two days and is suitable for farm animal manure, grass and vegetable waste treatment.

Testing of one of the three PG 1 digesters built for HM Prisons kitchens.
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.
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.
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.Back to Top
