Why Waste to Energy?

Waste stops being a management cost

A TVE plant works on three lines of your P&L at once: what you pay to get the waste out, what you pay for energy, and what you can charge to treat someone else's.

01

You stop paying for landfill

Every tonne you recover on site is a tonne that stops paying transport, levy and landfill. It is the line on your invoice that only goes up as European regulation tightens.

02

You stop buying gas and power

The heat, steam and power you produce displace natural gas and grid electricity in your own process. Your energy bill stops depending on a market you do not control.

03

You start charging for other people's waste

The gate fee you charge for third-party waste, and any surplus power exported to the grid, turn a treatment cost into an asset with its own revenue line.

And with the same project, the environmental file

  • Diversion of non-recyclable fractions away from landfill
  • Decarbonisation of scope 1 and 2 emissions in your own process
  • ESG eligibility and access to green financing when the fuel is biogenic

How we do it

Three phases, one single point of responsibility

We design, manufacture and commission the three phases in our own production centres. There is no need to integrate three suppliers, and no guarantee to argue over when something fails.

Inputs — what the plant receives

Input AWaste-derived fuels
RDF · CSR
Green RDF · compost oversize · biostabilised
Non-recyclable fractions — a high calorific value is not required
Raw MSW does not enter a grate: it is fed as RDF or SRF
Input BBiomass & organics
Agro-industrial and forest biomass
Wood and paper residues
WWTP sludge — up to 50% moisture
Up to 30% ash content
Input CHazardous waste
Chemical and pharmaceutical waste
Heterogeneous SRF · complex mixes
Industrial sludge with contaminants
Dir. 2010/75/EU · high gate fees
TVE process — 3 phases

The process — three sequential phases

Phase 1Combustion or oxidation

The fuel is thermally broken down on a grate or in a rotary kiln. This is where the temperature, residence time and emissions control required by your permit are set.

SGC — Moving step grate
USC — Underfeed stoker
RKC — Rotary kiln + afterburner chamber
Oxidation chamber when strict CO control is required
Phase 2Heat transfer

The hot gases hand their energy over to a working fluid in the boiler: thermal oil, steam or water. The choice of fluid decides which energy leaves the plant and how the boiler is protected.

HZB Horizon+ · rotary thermal-oil boiler
SPB · saturated or superheated steam, up to 40 bar / 400 °C
TOB · vertical thermal-oil boiler
HWB · hot or superheated water
TREN hybrid · thermal oil producing clean steam for the turbine
Phase 3Power generation

The working fluid drives a turbine coupled to a generator. It is an optional phase: when the project only needs heat, the plant stops at phase 2.

ATEX. Every thermal-fluid installation — the HTF circuit that carries the heat — is designed under the ATEX framework, the European explosive-atmospheres regulation, whatever the configuration, including thermal-only plants. We fit it to how demanding your own site is.

How we prescribe

We prescribe on evidence, not from a catalogue

Before we propose a configuration we settle two decisions, in this order: which thermal process your fuel and your permit allow, and which working fluid makes the most of that choice. There are four possible routes, and each has its own ground. We show you all four and explain which one fits your case best, and why.

Level 1 Thermal process — decided by your emissions permit and by the characteristics of your fuel
Level 2 Working fluid — decided by which energy it pays you to produce
Route A.1Steam cycle

High viability: less entrained ash makes the steam cycle technically feasible.

What it brings

  • The highest electrical efficiencies in the range
  • Mature technology, with decades of operation on the market and full supplier freedom

Where it fits best

  • Projects focused on net electrical output, with clean and stable fuel
  • The superheater is protected with Inconel — a nickel superalloy against corrosion — which the technical study sizes for your fuel
Route A.2Thermal fluid · ORC

The boiler runs clean and free of corrosion risk, which keeps cogeneration schemes open.

What it brings

  • Built on our own Horizon+ patent
  • Cogeneration schemes remain available

Where it fits best

  • Sites with strict CO limits that also want heat and power at the same time
  • Projects where cogeneration underpins the plant's overall efficiency
ModelsTVE-1
Local CO regulation Ash load and acid attack Cogeneration requirement ORC turbine supply and competitiveness Calorific value (LHV) and corrosivity of the fuel

On a small plant, when we refine the route

If combustion plus HTF/ORC is on the table, oxidation plus steam cycle gains ground when any of these apply: strict local CO limits (France, for instance), an exclusive requirement for net electrical output without cogeneration, or an ORC turbine supply context that favours another route.

In practice cogeneration is almost never ruled out in full by local rules: residual heat at 150–180 °C is still recoverable.

On a large plant, when we refine the route

If oxidation plus steam cycle is on the table, combustion plus HTF brings more when there are highly corrosive critical fuels, a regulatory framework that does not require an oxidation stage, or when your priority is thermal demand, that is, high-enthalpy industrial cogeneration.

The TREN scheme works equally well on small and large projects whenever combustion has been chosen.

Every prescription closes by characterising your actual fuel in our own laboratory, not a textbook fuel.

Waste to Energy solutions

Six configurations to adapt to your project

We order them by what actually decides the project: the fuel going in, and the energy you need coming out. They do not compete with each other: each one is designed for specific conditions, and all of them are tailored to the actual scope of your installation. Three of them are SWIP — Small Waste Incineration Plant, the regulatory category for a decentralised plant.

Thermal only

TVE-T

ThermoValue THERMAL

Process heat from waste-derived fuel. No power block.

Fuel
RDF · SRF · derived
Range
0,5 – 25 MWt
Phase 1
SGC · USC
Phase 2
HZB · SPB · TOB · HWB
  • The most direct configuration in the range: from waste to process heat in two phases
  • No turbine and no power cycle: simpler permitting and operation
  • Four thermal output formats to match your process
Design keys
  • Ready to grow: if you expect to generate power in the future, we design for it from day one so the plant is ready to take the power block when the time comes.
If your case is different
  • If your fuel is clean biomass rather than waste, look at TVE-4: the same platform, sized for biogenic fuel.
Ideal scale: Any size up to 25 MWt — multi-unit above
SWIP · ORC

TVE-1

ThermoValue SWIP-ORC

Thermal oil and ORC cycle. Maximum reliability on dirty, variable fuel.

Fuel
RDF · SRF · organics
Range
0,5 – 2 MWe
Phase 2
HZB Horizon+ · patent
Efficiency*
18,5 – 20,2%
  • Unpressurised oil circuit: the boiler runs clean and free of corrosion
  • First choice for cogeneration and high-ash fuels, whatever the plant size
  • Horizon+ is our own patent, and the ORC turbine comes under an exclusive supply agreement
Design keys
  • It needs no certified steam-boiler operator. Like any industrial plant, it has a plant operator.
  • Each Horizon+ unit has a defined nominal power: above it the plant is configured as multi-unit, with footprint and maintenance sized in the technical study.
If your case is different
  • If the fuel is clean and stable and you want maximum electrical yield above 3 MWe, look at TVE-2.
Ideal scale: Optimal below 2 MWe — and at any power when ash or cogeneration decide
SWIP · Steam

TVE-2

ThermoValue SWIP-VAPOR

Direct steam cycle. The highest electrical efficiency in the portfolio.

Fuel
RDF · SRF · low ash
Range
2 – 10+ MWe
Phase 2
SPB · 40 bar / 400 °C
Efficiency*
18,1 – 23,8%
  • The highest electrical efficiencies in the range
  • Mature technology and full supplier freedom — no single-vendor lock-in
  • At large scale it delivers its full potential: cycle and materials sized to produce electricity continuously
Design keys
  • It performs at its best with a stable, continuous load regime: this is the configuration designed to produce electricity all year round.
  • With higher-ash fuels the superheater is protected with Inconel, a nickel superalloy that the technical study sizes for your case.
If your case is different
  • If your waste supply is seasonal or the fuel carries a lot of ash, look at TVE-1 or TVE-3: thermal fluid is designed for those conditions.
Ideal scale: Optimal above 3 MWe with low ash load
SWIP · TREN

TVE-3

ThermoValue SWIP-TREN

Thermal-oil boiler feeding a clean steam train. Oil reliability with steam efficiency.

Fuel
RDF · SRF · high ash
Range
1 – 10+ MWe
Phase 2
TREN: HZB + steam producer
Efficiency*
16,6 – 21,8%
  • Cogeneration with steam, designed to measure with direct extractions
  • High ash and acid attack: the risk moves to a clean external exchanger
  • Conventional steam turbine: full independence from the ORC turbine supplier
Design keys
  • It integrates two fluid circuits, thermal oil and steam, into a single system: water treatment is a small fraction of the steam produced.
  • It is the most recent configuration in the range: it combines the Horizon+ boiler, with years of operation behind it, and the steam cycle, which has been on the market for decades.
If your case is different
  • If your fuel is clean, the load is stable and you only want electrical yield, look at the direct steam cycle of TVE-2.
Ideal scale: Small and large alike, wherever combustion has been chosen
BIO · Biomass

TVE-4

ThermoValue BIO

Clean biomass and sludge. The same platform as TVE-T, sized for biogenic fuel.

Fuel
Biomass · WWTP sludge
Range
0,5 – 25 MWt
Moisture
Up to 50%
Ash
Up to 30%
  • It shares its mechanical platform with TVE-T — a grate proven on waste — and is sized specifically for biomass
  • Renewable energy: ESG eligibility and access to green financing
  • Our own know-how in biomass combustion, manufactured in our centres in Spain, Turkey and Brazil
Design keys
  • Above 50% moisture we add a drying stage before the grate, integrated into the plant design.
  • The usual boiler is TOB, SPB or HWB; Horizon+ is reserved for very particular biomass.
If your case is different
  • If what you recover is waste rather than biomass, look at TVE-T, with equipment built for a more demanding stream.
Ideal scale: Any size up to 25 MWt — multi-unit above
HAZ · Hazardous

TVE-5

ThermoValue HAZ

Hazardous and heterogeneous waste. Rotary kiln with afterburner chamber.

Fuel
Hazardous · mixed SRF
Range
0,5 – 5+ MWe
Phase 1
RKC + afterburner
Burnout
> 99,9%
  • The configuration in the portfolio for hazardous, heterogeneous mixes
  • The gate fee on hazardous waste gives the project a solid, predictable revenue line
  • Highly bankable: a stable waste contract lowers the financial risk
Design keys
  • Designed for Directive 2010/75/EU: at least 850 °C for 2 s, and at least 1,100 °C for 2 s above 1% halogenated organics expressed as chlorine. The kiln and the permitting process are planned around those parameters from the outset.
  • Kiln capacity is sized project by project, against your actual waste mix.
If your case is different
  • If the waste is neither hazardous nor heterogeneous, the grate configurations (TVE-T to TVE-3) are designed for your stream.
Ideal scale: Optimal above 1 MWe

Six starting configurations, one that fits your project best and, often, alternatives that also work. We tell you which and why: every Bianna solution adapts to the real needs of your project, your sector and your client.

* Overall efficiency. Nominal theoretical values under ideal isolated conditions, not project measurements. Real performance depends on the load regime, on the fuel LHV and on the cogeneration scheme.

Ash load is the criterion that most often guides the choice ahead of scale: a high-ash, acid-attacking fuel finds its natural ground in the thermal fluid of TVE-1 or TVE-3, whatever the plant size.

Is this your case?

Find your case

Every profile arrives with a different problem. These are the four we see most, and the configurations that solve them.

Councils · Associations · Public waste companies

Municipal & public

What they tell us
  • Rising landfill cost and European regulatory pressure on buried waste
  • Need for municipal energy self-sufficiency and a lower energy bill
  • Hard to secure bankable financing without a stable waste contract
  • Maximum availability with limited maintenance resources
  • Raw MSW does not enter the plant as it is: it needs upstream preparation into RDF or SRF, which we also engineer
Agri-food · Paper · Chemical · Wood · Data centres · Isolated communities

Industry with its own waste

What they tell us
  • High thermal energy bill — steam, hot water, thermal oil — for the process
  • Continuous own-waste generation with high handling and transport cost
  • Decarbonisation targets on scope 1 and 2, and ESG reporting
  • Need for a plant that fits the existing process without stopping it
WWTP sludge managers · Forest biomass · Wood · Paper

Agro-industrial & biomass

What they tell us
  • Costly management of WWTP sludge with high moisture and ash
  • Build-up of biogenic residues that become a liability and a disposal cost
  • Seasonal LHV variability that conventional technology does not absorb
  • Renewable subsidies and green financing tied to certified technology
Recommended configurations
Chemical · Pharma · Hazardous-waste managers · Industrial estates

Hazardous & heterogeneous waste

What they tell us
  • Demanding rules under Directive 2010/75/EU on temperature and residence time
  • High gate fees that give the project economic solidity
  • Complex heterogeneous mixes that call for a rotary kiln rather than a conventional grate
  • High bankability — a hazardous-waste contract lowers the financial risk
Recommended configurations

What is the nature of the fuel?

Waste and biomass deserve independent solutions: each stream has its own platform, sized to measure.

What energy output do you need?

Cogeneration is rarely ruled out in full: residual heat at 150–180 °C is still recoverable.

What is the scale of the project?

Approximate target output. Scale refines the choice; it does not decide it on its own.

How strict is CO and emissions regulation at the site?

This is the first-level question: it decides between oxidation and conventional combustion.

What ash load and chemical aggressiveness does the fuel have?

This is the criterion that most often guides the final choice ahead of scale.

What is the main priority of the project?

The last input: it guides the choice when two routes remain technically valid.
