AeroThermals autoclave is a pressure vessel that steam treats its contents at a constant temperature and pressure, serving to sterilise,

clean, break-down lignin structures and reduce waste volume by approximately 60%. Then, by applying a secondary process the true

added value of the autoclave can be realised. These qualities can not only serve to increase landfill diversion rates, but if the process by-product, cellulose floc, is used to its full advantage, clean, green energy can be derived from waste.

Exhaustive trials and in-house analysis show the autoclave process modifies the cell structure of the waste and renders the material

suitable for a number of other processes.

For example, by employing Anaerobic Digestion (AD), an easily

accessible biogas is created, which can then be directly used to

feed gas powered generators, that will not only supply sufficient power

to operate the entire processing facility but also provide a surplus to

sell back to the national grid . As part of the AD process, the resultant

substrate can be further treated to derive even higher levels of energy

generation.

A subsidiary company within the AeroThermal Group, EnviroThermal, has

recently agreed worldwide technical and commercial development rights to

market an innovative fixed bed, multidirectional airflow, gasification unit, a

further example of the engineering expertise and range of complementary

products the group brings to the industry in which they operate.AeroThermals engineering competencies, business acumen and wide

ranging experience ensures the Company is well positioned to deliver

bespoke turnkey, process engineering solutions that can be tailored to suit

individual customers requirements, designed and implemented to world

class standards.

AeroThermals engineering competencies, business acumen and wide ranging experience ensures the Company is

well positioned to deliver bespoke turnkey, process engineering solutions that can be tailored to suit

individual customers requirements, designed and implemented to world class standards.

All large scale manufacturing in Europe is handled by AeroThermals European partner, specialists in large-

scale fabrications that require high standards of tolerance and finish. The company is ISO9001 certifiedand manufactures in accordance with the requirement of such c lassification societies as Lloyds Register,

TV and DNV. Their team of well-motivated and highly skilled people uses modern machinery in a

spaciously laid out production facility with a maximum hoist-capacity of 250 tonnes. The company is

situated on the banks of a major river in mainland Europe, so AeroThermals equipment can be easily

shipped anywhere in the world.

Plant destined for the US market is manufactured by AeroThermals

associate company, Thermal Equipment Corporation based in

Torrance, California. It has over forty years of design and fabrication

experience ensuring that our Group is able to maintain worldwideservice and customer support.

Example of 30,000 T p.a. MSWExample of 30,000 T p.a. MSW

There are three key size plants.

30,000 T p.a. (suitable for food waste)

90,000 / 100,000 T p.a. (suitable for MSW at local authority

level)

150,000 / 200,000 T p.a. (suitable for large scale MSW

processing facilities)

With a single autoclave system, comprising two machines, the

installation becomes modular, so that 1, 2 or 3 systems could

be operated in tandem depending upon the specific annual

tonnage requirements of individual councils, unitary

authorities or commercial enterprises

Features & Benefits

Key Operational Features and B enefits of Autoclaving WasteKey Operational Features and B enefits of Autoclaving Waste

2 autoclaves operating in parallel, capable of handling 15 tonnes MSW per load each (for this example only) means that with 24

hour operation the plant can handle up to 300 tonnes per day assuming the mass density to be 225 kg/m3.

As steam is recycled between the 2 autoclaves it significantly reduces the amount of energy the system requires.

The steam can be generated from waste heat from the electricity generation plant, powered by the production of methane gas.

There is minimal operational noise, offensive odours are reduced and harmful toxins are not released into the atmosphere.

Autoclaved waste has on average a 60% reduction in volume and with the liquid fraction separated at this point, the mass can

be greatly reduced.

For a plant managing 100,000 tonnes per annum the site requirement is a minimal three acres. Land take should be considered

to be on a sliding scale, meaning that a 30,000 t.p.a plant will only require one acre.

As the process can handle totally unsorted, black bag municipal solid waste at the same time as high organic fraction

supermarket waste and kitchen food waste, it is possible to combine industrial, commercial and residential waste management

strategies.

The system will process the waste at conditions that satisfy the Clinical Waste Regulations and both Category Two and Three of

the Animal By-products Regulations. Category One is also obtainable, should the in-feed be pre-shredded, subject to site

approval.

All recyclable materials will be gathered and sorted after the process and wil l be sterile and clean, therefore commanding a

better price within the open market.

Post Process OptionsPost Process Options

Post process options are one of the key benefits of autoclaving. The output can be dried, and subject to the amount of

organic fraction present, the liquid used to produce suffic ient biogas to meet the energy requirements of the plant. The

dried cellulose floc can then be sent for recycling within the paper and cardboard industry or it can be turned into a solid

biomass fuel for thermal treatment feed stock and used to produce further green electricity.

As autoclaving produces a hydrolysed, homogenised waste stream it is perfect for use in anaerobic digestion systems.

It will increase the potential gas volume by as much as 100% with a far faster rate of production.

Peak gas f low can be attained in as little as a quarter of the time of a standard AD system.

Key Financial Features and Ben efits of our system are:Key Financial Features and Ben efits of our system are:

DEFRA estimates that electricity output per tonne of waste is between 75 225 kw-hr, dependant on the quality of the

waste stream received (the higher the organic fraction, the higher the energy). With autoclaving the benefits are such that

the system will operate closer to the top of this range at about 200 kw-hr per tonne.

With a feed rate of 12.5 tonne/hr we will generate 2.5Mw.

With the allowances for green electricity, this is worth up to 15p/kw-hr or 24 per tonne of waste.

The plant is totally self sufficient in its own energy needs.

In 2009 England will see the introduction of the Landfill Allowance Trading Scheme (LATS) charged at 150 per tonne over

and above the current cost of disposal. Thus potential revenues for those with a robust waste strategy in place can only bebeneficial.

With an annual capacity of approximately 100,000 tonnes, this plant is well suited to service the needs of 200,000 people,

negating the requirement for any long distance transport or waste movement across local authority boundaries.
