Elvis Au (“Incinerator will adopt proven, cost-effective technology on island [1]”, August 5) continues to weave his tangled web of half-truths.
He revealed that of the HK$18.2 billion requested for the project, HK$12.7 billion is to build the incinerator and HK$5.5 billion (30 per cent of the total cost) to build infrastructure on Shek Kwu Chau.
So we will pay an extra HK$5.5 billion because vested interests do not want the incinerator built near the Tuen Mun landfill, which is the logical site.
The “balanced distribution of waste facilities” Au cites as the reason for selecting Shek Kwu Chau was never raised by the Environmental Protection Department from 2004 to 2010.
It surfaced only in 2011 after Lau Wong-fat, chairman of Tuen Mun District Council, objected to putting the incinerator in Tuen Mun.
The department then created the “balanced distribution” criterion to justify Shek Kwu Chau.
Getting approval for another site takes no more time than obtaining it for Shek Kwu Chau, that is, one year from April 2011 to April 2012.
On the capital cost, Au provides selective data.
A survey of all incinerators constructed shows that economies of scale lead to lower per-tonne capital cost the larger the capacity. Au chose Denmark’s lower-capacity 1,100 tonnes per day incinerator costing HK$4.27 million per tonne to compare to his proposed high-capacity 3,000 tonnes per day incinerator costing HK$4.25 million per tonne.
This is like comparing the per passenger cost of a bus to a Rolls Royce.
An honest comparison is with the per-tonne cost of high-capacity incinerators.
These include – the 2,300 tonnes per day facility in Runcorn, Cheshire, UK, at HK$2 million per tonne; the Afval Energie Bedrijf Waste Fired Power Plant in Holland with 3,800 tonnes per day capacity at HK$1.1 million per tonne; the 3,000 tonnes per day facility in Beijing at HK$1 million per tonne; the 1,600 tonnes per day facility in Riverside, Kent, UK, at HK$2.6 million per tonne.
Nor did Au mention the 1,000 tonnes per day incinerators in Finland, China, England, South Korea and Azerbaijan costing less than HK$3 million per tonne.
The 1,000 tonnes per day plasma gasification plant in Teesside, England, cost HK$3.1 million per tonne, paid by the operator.
If approved by the Legislative Council’s Finance Committee in October, Au’s Rolls Royce incinerator will cost between 100 per cent and 300 per cent more than similar capacity incinerators in the world.

If Tom Yam is quoting $ numbers then at least he should get them right, upfront.
The Govt and AU especially well know what they asked for:

5177DR: IWMF Phase 1 14.96bn – MOD – now 17bn
5163DR: NENT landfill ext 6.632bn MOD -now 8bn
5164DR: SENT landfill ext 1.76bn MOD -now over 2bn
5165DR: WENT landfill ext 33.4mn – now 36mn
The ‘package’ is at least 27bn!
The building of an incinerator is dependent on the capacity of the landfills being increased to handle the 30% by weight ash produced, so they are a ‘package’
Then need to ADD a Pulau Semakau island as the new ash lagoons (10 bn?)
So even at today’s money of day prices Shek Kwu Chau package is $9m per tonne
but by the time it would be finished (like the fast rail to nowhere) it will be far higher
Then, we have all the peer reviewed evidence showing increase in deaths, cancers, birth defects, orofacial clefts in spatial proximity to incinerators
Only with a Rubber Stamp person I/C EIA approvals could this be allowed to happen & she wears two hats & has never knocked back a Govt EIA to date!
The correct numbers sought in Legco by ENB included ALL the infrastructure as shown here:
5177DR – LEGCO REQUEST FOR FUNDING 2012
IWMF PHASE 1 FUNDING REQUEST 14.96 BN INCLUDES THE ISLAND COST AND MUCH MORE AS SHOWN BELOW

4.1.1.4 Scope of work
4.1.1.4.1 A plan showing the location of the IWMF Phase 1 at the SKC site is at Annex B1. The IWMF will be built on an artificial island
formed by reclamation to the south-western coast of SKC. The reclaimed island will measure about 11.8 ha including a berth area and storage area
for waste containers. Due to occasionally rough sea condition in the vicinity, the project will include constructing a breakwater of about 4.1 ha
to ensure that loading/ unloading activities can be safely carried out in the berth, and that the safety of facilities can be guaranteed.
4.1.1.4.2 The scope of 5177DR comprises –
(a) design and construction of reclamation to form an artificial island near SKC;
(b) design and construction of an MSW incineration plant of a design capacity of 3 000 tpd employing advanced moving grate waste-to-energy technologies. The incineration plant will comprise the following main components –
(i) waste reception, storage and feeding system;
(ii) moving grate incinerators;
(iii) waste heat recovery, turbine generator and cooling
(iv) boiler feedwater treatment system;
(v) flue gas treatment and discharge system;
(vi) fly ash, bottom ash and residues storage, treatment and handling system;
(vii) bulky waste storage and handling system, reagent
reception and storage system; and
(viii) process control and monitoring system;
(c) design and construction of a mechanical sorting and recycling plant of a design capacity of 200 tpd. The mechanical treatment plant will comprise the installation of the following main components –
(i) waste reception system;
(ii) mechanical sorting and shredding system; and;
(iii) process control and monitoring system;
(d) provision of ancillary and supporting facilities including submarine power cables and electrical system connecting the artificial land to Cheung Sha of Lantau Island, a desalination plant providing water supply to the facility, a wastewater treatment plant, an environmental education centre, community facilities1 and minor supporting facilities for a marine park2; and
(e) environmental monitoring and auditing during the
construction stage.
A layout plan showing the proposed works is at Annex B2. Subject to funding approval of the FC, we plan to commence the design and
construction works in September 2013 and commission the IWMF in 2018/19.
