Why Treat Food Residues On-site?
• Resource Recovery and Reuse
• Tightening Legislation
• Rising Costs
• C-footprints
• Hygiene
• Storage, Scavengers & Vermin
• Beneficial Products

In-Vessel Composting
Key Features:
 Enclosed vessel gives accelerated composting
 Continuous process for compatibility with waste arisings
 Optimisation of environment for microbes through intermittent but
frequent automatic & controllable turning to ensure the whole mass
is advanced and regularly exposed to aerobic conditions
 Pasteurisation achieved in 9-14 days producing odourless composted
product
 Hygienically produces compost on a small scale; Suitable for small
industrial & catering units, hotels & restaurants, prisons, universities etc.
 Temperature monitoring for ABPR compliance – PC downloadable
 Numerous units across UK ABPR approved

In-Vessel Composters IVC
• contained, controlled, hygienic, quicker composting process
• higher throughput - more commercially viable
• ABPRegs 2003 Compliance: P16 single premises exempt if compost
used on site

NB - What mixture MUST I use?
High Nitrogen Waste
High Carbon Waste
e.g. Food waste
including:
e.g.Wood Pellets
Chipped wood waste
or
Meat
Wood chip from trees
Fish
Waste / broken pallets
NB. Chipped wood
provides a better
structure than shredded
wood or wood shavings,
but shavings and
sawdust can be used in
small amounts to alter
moisture levels.
Vegetables
Fruit
NB. When wet food waste
is used we recommend
using a dewatering
system to remove excess
water to achieve 60-65%
moisture.
+
e.g. 1:1 (by vol.) ratio of food waste & wood chip (30-35:1 C:N ratio, 60 – 65% moisture Level)
CAN NOT COMPOST PLASTIC, METAL, GLASS

How the IVC Systems Work
Fresh
damp
waste 60%
– 65%
water
Excess
water is
drained to
a sump for
re-use or
disposal
after
further
treatment.
Water vapour and CO2 are produced by
the composting bacteria throughout the
process and they are vented to
atmosphere or further treatment if
required.
Getting dryer throughout process

Maturation zone

Exiting product – 40% 45% water
Dry
product
goes to
maturation
area for 4 8 wks.

Carbon Footprint
• Every t food waste generates c15t CO2eq
• On site composting saves c90% CO2eq emissions
• An Hotel doing 500 covers/day will generate c1t/week
• = c50t/a
• = 3 VW Golf 2.0 Tdi doing 50,000m/a off the road.
