Case Study: Fruitful Collaboration
Terra Nitrogen: Industry produces
derivatives of nitrogen and methanol.
 Waste:12,500 tonnes of CO2 released
to atmosphere, hot steam and
ammonia.
John Baarda: Tomato producer
 Additional production capacity
limited due to high costs of energy
Partnership
•Elimination of CO2 emissions
•Construction of a greenhouse
capable of producing 300,000
tomatoes per year
•Investment of £15M
•Creation of 65 new jobs
•Recovery of heat from steam

Case Study: Innovation in materials
Companies:
• Mil-Ver Metals
• Denso Manufacturing UK
Summary:
• Hazardous waste generated from Denso
producing air conditioning units was collected
and reprocessed by Mil-Ver for use in its
manufacturing process
Achievements:
• Cost Saving €45,000 per year
• Hazardous waste eliminated 15 tonnes per year
• Carbon emissions reduced by 242 tonnes per year

Case Study: Redevelopment of a hospital
Companies:
• Skanska
• Armoury Demolition
Summary:
• Skanska needed to address voids
from low depth mines during
redevelopment of a hospital
Material from a high rise demolition
was used to create a stone blanket
prior to piling
Achievements:
• 11,550 tonnes material reused
•>£250,000 cost savings

Case Study: Scallop shells to forestry
Companies:
• West Coast Sea Products
• Forestry commission
Summary:
• Over 1,800 tonnes of shells generated per year
Shells incorporated in to sub-base aggregates for
forestry roads
Also used as top dressing of roads – decreasing
punctures
•Release calcium, reducing effects of acidification of
waters
•Decrease in disposal costs of £25,000 per annum

Case Study: Cambridgeshire Guided Busway
• Cambridgeshire County Council is in the process of building the
longest guided busway in the world.
• NISP working on CGB at site clearance stage:
– Outlet found for 20,000 railway sleepers
– Sourced 3,000T of recycled aggregated for temporary roads
• Request to source 60,000m3 of drainage material
– NISP proposed tyre shred as an alternative

NISP facilitation
• Tyre recyclers introduced to Major
Contractor
• 18,000T of tyre shred used
• Replaced 60,000T of aggregate
Outcomes
• Significant project cost savings
• >6,000 tonne CO2 saved
• Replication for next project
Case Study: Cambridgeshire Guided Busway

Case Study: IS Transforms Individual Businesses:
e.g. John Pointon & Sons Ltd
• Pre – NISP: animal renderer
inputs: carcasses
outputs: landfill
perception: dirty industry
• Initial NISP stage: animal by-products diverted from
landfill to cement industry
• Second stage: improved efficiency of processes
• Third stage: move into bio-fuels utilising more by-
product
• Fourth stage: move to AD and grid connection
• Fifth stage: transfer in of innovative technologies
• Current situation
inputs: carcasses, organic residues
outputs: energy, minerals
vision: clean energy company
“Long term culture change needs
long term business engagement”

Case Study: Business Solution for Foundry
Waste
• Links to foundries via Cast Metal
Federation
• Identified ways to reuse spent
foundry sand to brick manufacture
• Sustainable solution rather than
landfill
• Additional Sales - £200k
• Landfill Diversion – 10,000 te
• Cost Savings - £300k
• Virgin Materials – 10,000 te
• Jobs Saved - 42

A Powerful Alliance for Subcontractors
WPD and East Alliance Partners
NISP worked with WPD (then E-on) to
increase the amount of recycled
aggregates used on sites and reduce
landfill costs via their contractors.
NISP created a Workspace so data about
local recyclers could be shared between
the East Alliance Partners. One common
Compliance Checklist was created which
amalgamated the individual Partners’
forms. This was used to assess new suppliers
joining the Framework.
The results include:
•Diversion from landfill: 73260 tonnes
•CO2 reduction: 168 tonnes
•Cost savings: £76077 per year

CHECKLIST/QUESTIONNAIRE
Plant Operator
Local address
Registered address
What Geographic/Highway Authority areas can you supply to?
YES NO
Waste Management requirements (QP ref* 3.4.1, 3.4.4, 3.6.1 and 3.7.1)
Does your recycling operation have the required environmental permit/waste management
licensing/exemptions and is the Duty of Care applied?
NOTE: You must demonstrate that you meet the statutory and regulatory requirements, including use of registered waste
carriers and Waste Transfer Notes (WTNs). Please consult the Guidance Notes for further details.
Do you hold a Waste Carriers Licence?
Have you had any EA prosecutions in the last 3 years?
Acceptance of incoming waste (QP ref 3.4.1 to 3.4.4 and App C)
Do you have site/location specific Acceptance Criteria procedures for the incoming waste?
Do your Acceptance Criteria include a description of the types of waste accepted and a
description of the method of acceptance?
NOTE: List of Waste Regulations/EuropeanWaste Code for consistency with the WTNs must be used. You must
demonstrate that only inert waste is accepted for production of aggregates to the Quality Protocol. Inspection at receipt
and at tipping must be carried out.
Please list what EWC codes the site/ location can accept?
Are material input records kept?
NOTE: A record of each load received and accepted must be kept
Do you have a procedure for non-compliant waste?
NOTE: You must demonstrate how you are dealing with non-conforming incoming waste. Please consult the Guidance
Notes for further details.

• Tarmac Building Products was
looking for alternative materials as
fill material in lightweight building
blocks
• Witherley Services was managing a
large stockpile of blast furnace slag
and looking for routes to market
The results include:
• 17,300 tonnes of material was
diverted from landfill
• 1777 tonnes of carbon dioxide
savings & Cost savings for Tarmac
versus expensive raw materials

Sludge reutilization
Tianjin SembCorp Sewage Treatment Co. , Ltd. operates a
sewage treatment plant in Tianjin Harbor Industrial Park.
The HanGu landfill site doesn't receive sludge according
to the new policy in TBNA.
A safe and economical method for sludge treatment is in
great need.
Yuchuan is a professional sludge treatment company,
whose core technology is extracting protein from sludge
for the manufacturing of protein products.
The two companies met in the 9th QWW and came up
with a potential synergy.
Yuchuan receives 15 tons of sludge from SembCorp per
month.
