Reducing Risk in
Service Delivery
Tim Walker
Head of Waste Management
Issue
• A s clim ate change
progresses & its effects
m anifest them selves m ore
frequently, strategic
planning is not a question of
“if” but “how” w e deliver in
these challenging conditions
• T he rem oval of w aste is an
essential/universal service
w ith obvious public health
im plications; the C ouncil has
a statutory duty to ensure
this is delivered through
resilience planning & risk
m anagem ent… O h, & then
there’s target com pliance…

C om post
C ollection P ractices – F looding • M ore than 60,000 households in N I already lie w ithin areas at risk of flooding • In w orst case, councils are unable to access properties • D isposal of flood-dam aged/w aterlogged m aterials can stretch bulky w aste services + R ecycling C entres • S toring item s for m onths for insurance assessm ent can cause public health issues (sm ell, verm in, & c) • H ow ever, m ore prosaically is the ability to continue to deliver services during persistent heavy rainfall • In this instance, higher-quality w aterproof gear to staff ensures this w ill happen – w ith a higher cost for providing these to staff
R eceptacle Issues - W ind
• W ind can blow bins & boxes
over w hen full
• B ecause focus is on keeping
recyclables dry, they can be
blow n
• T his creates an increase in
litter w hich then requires
additional resources & costs
to councils to clean up
• C ustom ers can assist by
placing w eights on their box
lids to help prevent this – but
not all do so
W aste Issues – S now
• S now creates hazard ous conditions for both
vehicles & staff
• T he C ouncil has sourced snow -grips for
vehicles & also staff footw ear to allow
operations to continue w here reasonable
• T here is considerable disruption and, again,
increased costs
• W here staff are unable to discharge norm al
duties, they are reassigned to snow
clearance on streets & , particularly, the city
centre to m aintain pedestrian access and
assist in com m ercial trading – m ore relevant
to urban rather than rural areas (?!)
• R ecycling C entres get snow ed in – issue
w ith public access
• Im pact on organic w aste– M ar ‘13 reduced
annual recycling rate by ½ %
S taff Issues – S un
• S un can have particularly dam aging
effects on staff constantly exposed
w hilst w orking – w aste/recycling
collection, R ecycling C entre
oeprations
• T he C ouncil does not provide sun
cream , or any other types of cream ,
due to the derm atological effects it
can have on different skin types, &
liability
• P ersonal P rotective E quipm ent (P P E )
is provided w hich includes hats &
long-sleeved tops w hich give
protection from the sun – but shorts
are not perm itted at any tim e
F leet Issues – C O 2
• C O 2 em issions from vehicles are, in part,
addressed through procurem ent w ith the
latest E uro N C A P V standard
• V ehicle fleet em issions are tested during
routine servicing
• P articulate traps fitted to R C V s
• U se of ultra-low sulphur diesel
• P rogram m ed replacem ent of fleet
• A lternative fuels such as bio-diesel/gas
considered but, due m odern engines to
reduce em issions, these are largely unable
to run on alternative fuels
• A prototype electric R C V has been
developed but the cost is prohibitive until
such tim es as the technology im proves and
the production costs fall (the C ouncil’s funds
com e from the public purse so value-for-
m oney often trium phs)
E fficiency
• T he m ost effective m eans of reducing
em issions & C O 2 footprint is
m axim ising route efficiency &
m inim ising num bers of vehicles
• R oute optim isation softw are is now
highly developed w hich allow s the
structuring of routes w ith pin-point
accuracy & a levelling of
w orkloads/capacities to an extent far
beyond that previously achievable by

• T he m ajority of the w aste is stored below
ground level w here it is kept cool. W hen
new w aste is added, it covers old w aste.
T he oldest w aste being at the bottom of the
container w here it is stored at cooler
tem peratures. T he low er tem peratures
reduce bacterial activity - prom oting
hygiene. T his m eans that the bin is virtually
odour free.
• A s the w eight of new w aste being added
com presses older m aterial, the w aste
naturally com pacts itself. O ver tim e a
com pression rate of 2:1 is often achieved.
• 60% of the bin is beneath the surface w hich
m eans that you can have high capacity
w aste storage in a sm all surface area.
• T he bin opening stays at a safe height. T he
lid also shuts autom atically – so anim als
