Agenda

• Introduction

• The ‘Hot-Spots’

• The Problems

• The Law

• The Solutions

• CBio

3

Introduction

• 100,000’s FOG related blockages in the UK,

costing £80m p.a. to clear

• Serious environmental consequences

• Majority are caused by commercial catering

establishments – 400,000 in the UK

• Law requires them to deal with their FOG –

few do

4

The Hot-Spots

• Dishwashers

• Pot wash / Rinse Sinks

• Combi-ovens

• Macerators

• Floor channels

• Potato rumblers

• Decarboniser units

5

The Problems

6

The Law• Building Regulations – PtH1 para 2.21

– Requires that all kitchen drainage in commercial hot food premises should be fitted with an effective means of grease removal.

– Failure to adhere to these laws can lead to enforcement and prosecution

• Water Industry Act 1991 – Section 111– Criminal offence to discharge any matter which may interfere with the

free flow of wastewater– Costs incurred by the water company can be legally recovered– Prosecution can result in substantial fines and even imprisonment

• Environmental Protection Act 1990 – Duty of Care– Ensure all waste is managed from point of production right through to

point of disposal– Ensure the collector is a “registered waste courier” and waste is taken

to a licensed disposal site

7

The Law

• Environmental Protection Act 1990 - Statutory Nuisance– Smells, effluents, accumulation of refuse, risk to health, nuisance– Serve an “abatement notice”, failure to comply can result in

prosecution and cost recovery

• Animal By-Products Regulations EC - 1774/2002 (ABPR)– Since Nov 2004 waste cooking oil can no longer be used as an

ingredient in animal feed– Must be collected via a licensed waste carrier

8

The Law

• Building Act 1984– Local authorities require satisfactory provision for drainage of an

existing building by service of a notice on the owner– This can include a requirement for the installation of a grease trap

• Food Safety Act 1990– Local authorities are authorized to inspect premises– Problems arising from FOG on drains could result in prosecution or an

order to prevent trading on premises

9

The Solution These all have a role to play

• Management

• Training

• Interception• Active

• Passive

• Treatment• Biological

• Chemical

• Maintenance

• Enforcement

10

Training & ManagementThere’s one simple message:

“DON’T PUT IT DOWN THE DRAIN!”• Clarity

• Consistency

• Ownership

• Assigned Responsibilities

• Issues• Management Understanding

• Staff Turnover

• Staff Motivation

• Time

• Management Reinforcement

11

Interception

• ACTIVE – point of source grease/food separation and collection

• Examples – GB GRU, Fatstrippa, Grease Shield, Grease Guardian, Big Dipper, Food strainers

PRO’s CON’s

Can be highly effective – 95% efficiency Expensive

Minimal staff maintenance – 1-2 min/day Difficult Installation (gravity discharge dish washers)

Doesn’t hold grease long enough to cause smells Unsympathetic if you forget to service

Unsympathetic if you forget to service Requires daily staff maintenance

12

Interception

• PASSIVE – designed to separate grease and hold it until emptied

• Includes small under-counter traps from 5ltr to large under-ground traps of 5,000 ltr

PRO’s CON’s

Cheap Unhygienic if not cleaned regularly

Simple Rarely emptied as often as they should be

Many suppliers / installers Smells / floods

Work well if correctly sized Expensive contractor required to clean properly

Rarely correctly sized – space restrictions. Needs minimum residence time.

13

Treatment• BIOLOGICAL – bacteria / enzymes used to digest FOG in the drainline

• Can be used in small drains, pump stations, sewer lines and treatment works

PRO’s CON’s

Cheap Requires regular top-ups

Simple installation Can struggle if incorrectly located / short residence time.

Easily maintained On-going maintenance/fluid cost

Works well if correctly located and in the right environment Enzymes – ‘single-use’ product

‘Fit & Forget’

Bacteria – Continued effect after dosing

14

Treatment• CHEMICAL – chemicals used to breakdown FOG in the drainline

• Can be used in small drains, pump stations, sewer lines and treatment works

PRO’s CON’s

Cheap Frequently uses hazardous chemicals

Simple application Can damage downstream assets

Easily maintained FOG recombines after initial breakdown

‘Single-use’ product

Reactive application

Waste Collection Record

FOG Removal

Food Waste

21

The Site:• Medium sized food led pub• Sensitive treatment plant, costing £1k/day to maintain• Producing c.1,400 covers/week

The Unit:• GRU 2 installed on trial in January 2012

The Trial:• Waste food and oil collected for a 5 day period in March during which the site was relatively quiet.

The Results:• Over 7kg of food waste and at least 5lt of waste oil was collected.• This represents c.1 ton of waste food and oil collected p.a.• FOG levels in the outlet measured at <4ppm

The Conclusions:

• An average kitchen produces at least:• 7g food waste/cover• 5ml oil waste/cover

• GB GRU reduced the BOD load on the STP by c.50%

GreaseBeta GRU - Results

22

GreaseBeta Strainer• GB Strainer is a stand alone food solids

strainer.

• Easily installed beneath the pot wash and rinse sinks.

• Simple slide out catch basket, capable of collecting in excess of 1,000kg of food waste p.a.

• Can be used in conjunction with GB BIO & up-stream of GB GRU.

• Cannot be by-passed by the operator and does not restrict sink discharge flow rates.

The GB Strainer removes all food waste, a key component of FOG related issues

23

GreaseBeta Strainer Action

24

GreaseBeta Trap• The GB Trap is a full range of internal fat traps

5lt – 200lt volume

• Each trap comes with an in-built solid strainer

• Works in conjunction with GB BIO units to minimise grease build-up inside the unit

• The GB Clean service ensures that any trap can be emptied as often as is required

• CBIO can specify and supply large (c. 5,000 ltr) out-door GRP underground, 2 or 3 stage grease separators. CBIO can also arrange for the civil engineering work to be undertaken if required

25

GreaseBeta BIO

Advantages• Compact pump easy to install and maintain

battery operated• Utilises entirely natural biological fluid and

processes• Complete digestion (no disposal costs)• Fully maintained service available• Unlimited pump guarantee providing CBIO

fluid in use (third party damage not covered)

NB - When used with an existing grease trap

will significantly reduce the required desludge frequency.

26

GreaseBeta Aer8• GB Aer8 is a biological Pump Station Conditioner.

• The system doses a range of bacteria, macro and micro nutrients into the sump and also injects 240 ltr/min of air into the effluent.

– This converts the septic sump into an aerated bioreactor.

• The unit requires a mains power source and access to the pump station itself, all usually available via the control kiosk.

The GB Aer8 eliminates pump station odours, fat blockages and septicity

27

GreaseBeta Clean

• Grease management equipment will only perform consistently if it is looked after.

– All GB units can be installed, serviced and maintained by the in-house service engineers.

– This includes fat trap emptying as part of a regular service regime.

– All waste collected is fully traceable to an official waste collection site.

– All maintenance and service visits are pro-actively managed by our experienced administration team.
