Definitions

  • This invention relates to advanced production techniques in compost, energy, and fuels from wastes, which are primarily more robust and efficient than previous methods.
  • Such production techniques can be utilised with various materials across a range of sectors, including commercial, industrial, agricultural and horticultural products, as well as a variety of sludges and effluents.
  • MSW Municipal Solid Waste
  • biodegradable e.g. food, paper, cardboard, garden waste, etc.
  • Global legislation is on the increase in an attempt to divert waste from landfill.
  • Waste treatment is one of the world's ever-increasing concerns. Methods used today, mainly landfill and incineration, are not sustainable and give rise to both environmental and economic problems. Few large-scale waste treatment plants work in harmony with the eco-cycle; instead they often create new problems. The latest innovations are therefore focusing on large-scale, reactor-based biological systems with reliable quality control. Such progression makes it possible to utilise the carbon rich fractions in waste as feedstock for renewable energy and fuels. In addition, overuse of chemical fertilisers has depleted the humus in our soils, thus driving the need for a more natural compost product.
  • MSW and other wastes are incinerated as a way of disposal. Combustion of waste by incineration is a growing public concern, which includes issues such as undesirable toxic emissions and hazardous ash. At the same time, operating standards are becoming more stringent the world over, thus incinerators are becoming increasingly more costly to build and operate.
  • Waste to energy facilities will receive mixed MSW, which is shredded and screened using say a 90mm trommel screen to provide certain quantities of Overs' and 'unders', as seen in Fig 1.
  • the Overs' (>90mm) will contain mainly dry non-biodegradable material, such as plastics, textiles, paper, metals, etc., which will normally passed through an air classifier to separate out the dry 'fines' from the wet 'heavies', with the dry 'overs' and 'fines' used as RDF/SRF in energy production - Fig 1.
  • the 'unders' ( ⁇ 90mm) will contain mainly wet biodegradables, such as foodstuffs, garden waste, etc.
  • An object of this invention is to provide advanced methods for processing waste materials more efficiently and cost effectively into energy, fuels and compost.
  • This invention also allows for more efficient extraction of high quality biomass from waste, enabling humus and nutrients to be recycled back into the land.
  • the invention can be best described by using an example of the design and operation of such a waste to energy, fuels and compost plant.
  • An average waste to energy facility will process about 1700 tonnes of mixed waste per day, which, for example, will have a particular composition - Fig 2
  • This invention provides for more robust production methods, which are more efficient in reducing the moisture content from circa 50% down to around 20%.
  • the invention also provides for methods to classify and homogenize such waste materials, whilst driving off the moisture. Such methods enhance the overall productivity of the downstream equipment, as well as vastly improving the quality of the end-products and thermal efficiencies of the energy recovery.
  • a rotary bio-drum is used to simultaneously dry and size- reduce the wet biodegradable fraction through a combination of biogenic and auto-thermic heating, variably controlled airflow and temperature, as well as the continuous tumbling of the material within the bio-drum.
  • the waste material is presented to the loading hoppers of the bio-drums, from where it is transported to the ram feeders at the loading end of the bio-drums.
  • the ram feeders are controlled to deliver the correct amount of material daily to each of the rotary bio-drums.
  • the rate of delivery is determined by the required moisture content and the maximum particle size in the final biomass.
  • Tonnages, flow rates, moisture and energy contents are dependent upon the nature of the wastes delivered, therefore subject to variation from day to day.
  • the incoming waste is shredded, with the output passed over a 90mm trommel screen to separate the paper, card and plastic for the production of SRF and onward thermal energy, or fuel recovery.
  • the remaining sub-90mm fraction is mixed with the 'heavies' fraction from the air separator and passed to the bio-drum for drying and sizing, in order to prepare it for further screening and manufacture into biomass.
  • test rotary bio-drum measured 185ft (56m) long x 12ft (3.5m) diameter, however, bio-drums can be 230ft (70m) by 20ft (6m) for larger waste systems.
  • Air is supplied through the discharge end of the bio-drum and directed to the front, or loading end, of the bio-drum.
  • the air is provided by means of positive displacement blowers, for example, a Roots URAI-615 blower, driven through a gearbox by a 15kW electric motor.
  • the output of the blower is coupled to the rotary bio-drum via a 100mm diameter rigid pipe, plus 1m length of 100mm diameter flexible pipe, which is coupled to a 100mm diameter swivel joint, co-axially mounted through the centre of the discharge end plate of the bio-drum.
  • the swivel joint also accommodates a 25mm diameter compressed air pipe that supplies the pneumatic cylinders to operate the bio-drum discharge doors.
  • the airflow is provided to the fully laden bio-drum at 321ACFM (9.1m 3 /min), with a back pressure of 3.5 PSI (0.24 bar).
  • Control system monitors the feeding rate to ensure the maximum load within the bio-drum does not exceed the Safe Working Load (SWL), typically 66%.
  • SWL Safe Working Load
  • bio-drum capacity should provide sufficient redundancy in the event of any bio-drum outage.
  • the amount of moisture that can be removed from each rotary bio-drum per day is a function of (1) the ambient air conditions, (2) the temperature of the air within the bio-drum and (3) the output air conditions.
  • two Roots URAI-615 blowers are used per bio-drum, coupled through a manifold to the air delivery pipe at the discharge end of the bio-drum.
  • ACFM (87.8m 3 /min) will be approximately 61kg/min, or 88.5 tonnes per day.
  • 175 tonnes per day (tpd) of wet waste material was introduced to the bio-drum at 49.9% moisture, resulting in 122.3 tpd of dried material unloaded (@ ⁇ 30% moisture), giving 52.4tpd of water evaporated.
  • the air extraction system at the loading end of the bio-drum needs to be designed such that the increased volume of 3100 ACFM (87.8 m 3 /min) can be extracted without increasing the backpressure of the combined bio-drum and pipework above the 7 PSI (0.48 bar) blower limit.
  • a custom designed heater is installed in front of the air blowers, for example, a cylindrical type Flow Torch 800, or similarly modified 'inline heater'.
  • the Flow Torch 800 heater will supply 43.9m 3 /min of warm air to each of the two Roots 615-URAI blowers at 37.8°C, resulting in 87.8m 3 /min drying air entering the bio-drum at 82.2°C.
  • the contents are discharged from the rotary bio-drum and transported to the Material Recycling Facility (MRF). Here it is screened to remove non-biodegradable material, prior to pelletizing for further processing, or shipment off-site.
  • MRF Material Recycling Facility
  • biodegradable fraction of the 'unders' and air separator 'heavies' have been dried and sized in the bio-drums.
  • This material may still contain some plastics, glass, stones and metals, which can be readily removed by additional screening.
  • Ferrous and non-ferrous metals are removed from both the non-biodegradable material using magnetic and eddy-current separators.
  • the biodegradable material is passed through a density separator to remove the light and heavy fractions, which leaves a relatively clean dried biomass to be transferred to a storage bunker for processing into compost or energy
  • the invention there are advanced methods for producing energy and fuels, including compost like products, from waste, including: using a specially designed ram feeding system to convey un-shredded or shredded mixture of waste materials into a custom designed hydraulically, or mechanically, driven rotating bio-drum that is best described as a mechanical biological treatment rotary bio-drum system; breaking down the biodegradable fraction of the mixed waste in around 2 days by both microbial and mechanical activity; regulating the environment within the rotating bio-drum using air and water to create the optimum biological activity; using increased air flow at elevated temperatures towards the backend of the rotating bio-drum to reduce the moisture content prior to discharge; following the 2 day residence time in the rotary bio-drum, the biodegradable fraction of the waste is less than say 25 mm in size, so it is readily separated from the non-biodegradable fraction that remains mostly whole; discharging the dry homogenised waste material from the rotary bio-drum and conveying it to a primary screen that readily separates the biodegradable material, or high quality biomass, from the non-biodegrad
