Refuse Derived Fuel Pellet Plant in Vietnam

RICHI MACHINERY

The Fuel Customer Must Be Agreed Before the Blend

The client supplies alternative fuel to industrial users in southern Vietnam. Its manufacturing requirement is to make identified fuel batches under its own control, with less dependence on finished material bought from other processors. That calls for a defined acceptance specification, not simply a machine able to compress whatever residue is delivered.

At the refuse derived fuel pellet plant in Vietnam, the intended outlets are industrial installations qualified to receive and use the specified waste-derived fuel. Each customer agrees fuel properties and delivery conditions for its process. A cement-kiln route and an industrial-boiler route may have different acceptance limits and handling requirements.

Paper-fibre residue can contain mineral filler, contaminants or a high water load. The operator therefore checks the actual residue source, composition and legal classification before approving it. Neither the word paper nor the presence of biomass makes every resulting blend automatically renewable, non-hazardous or acceptable to every combustion installation.

The 1,755 m² Building Is a Working Process Area

The fuel pellet plant uses 1,755 m² of covered space within the customer’s host premises. The area is divided into functions that support an 8 T/H route, with planned deliveries and regular bulk dispatch. It is not assigned several thousand tonnes of indoor storage without a volume calculation.

Covered function	Area	Working use
Receiving and feed preparation	450 m²	Unloading buffer, inspection and size preparation
Forming and finishing	450 m²	Two forming machines, cooling and grading
Raw-material store	430 m²	Identified accepted dry residues
Finished-product store	405 m²	Released bulk fuel awaiting collection
General waste holding	10 m²	Segregated non-hazardous rejects
Controlled waste holding	10 m²	Appropriate containers for maintenance-related wastes

For storage planning, a reference 250 kg/m³ incoming bulk density and 500 kg/m³ finished bulk density are used with a 2.5 m working depth and access allowance. Indicative working limits are 120 tonnes of raw material and 200 tonnes of finished fuel. Actual limits follow measured density, fire precautions and the approved site arrangement.

The refuse derived fuel pellet plant in Vietnam therefore relies on scheduled material movements. Vehicle turning and loading are checked against the host site’s external access; the covered working area and the host property’s external circulation are shown separately.

Cylindrical Fuel Sized for the Receiving Installation

The refuse derived fuel pellet plant in Vietnam forms cylindrical product, normally within a selected 16–20 mm diameter range and approximately 20–50 mm cut length. The fitted die and cutter establish the ordered grade. Product dimensions are measured on the cylindrical pellets delivered to the receiving installation.

Finished moisture is targeted at no more than 12% for the selected dry-feed route. Heating value, ash, chlorine, sulphur, relevant metals and other customer requirements are checked for the actual material. Bulk density uses a stated test method so the buyer can compare fuel deliveries on the same basis.

The annual plan follows 8 T/H for 20 net processing hours a day over 300 operating days. This gives 48,000 tonnes of finished fuel. The design schedule uses qualified feedstock, with cleanout and maintenance outside the net-hour calculation and dispatch planning tied to the daily production programme.

Dried Paper Fibre Is Different From Wet Paper Sludge

The annual accepted-material allowance for the refuse derived fuel pellet plant in Vietnam is 48,980 tonnes. The reference balance uses 12% incoming and finished moisture with 2% dry-material loss through sorting and handling. Wet residue is not counted as if every incoming tonne became a tonne of dry fuel.

Accepted material	Annual allowance	Boundary condition
Dried, approved paper-fibre residue	29,388 tonnes	Known source, suitable analysis and no free water
Clean sawdust	9,796 tonnes	Qualified material and controlled moisture
Prepared agricultural straw	4,898 tonnes	Soil and contamination controlled
Prepared bark	4,898 tonnes	Approved size, moisture and ash characteristics

Paper-fibre residue must arrive in a suitable dried condition for this equipment package, normally within 10–12% moisture. Fresh sludge requiring dewatering and bulk drying follows a separate upstream process. That equipment and its thermal energy are outside the defined dry-feed installation.

At the refuse derived fuel pellet plant in Vietnam, each stream remains identifiable before blending. Sampling checks composition and moisture as well as physical contamination. A source with excessive ash or chlorine is not made acceptable merely by giving its pellets a consistent diameter.

The recipe is established with the intended industrial buyer. Changing the paper-residue supplier or adding a different waste stream requires another acceptance and process assessment. Controlled woody and agricultural fractions support a repeatable blend, but they do not erase contaminants introduced by an unsuitable residue.

Fuel-analysis reports identify whether results are expressed as received or on a dry basis. Moisture can change delivered heating value even where the dry material is similar, so the operator and buyer compare the same reporting basis. Source changes are assessed against the agreed fuel grade and the receiving process. This makes the fuel-quality discussion specific enough to guide purchasing, blending and the customer’s acceptance sampling.

Utilities Follow the Dry-Feed Boundary

The refuse derived fuel pellet plant in Vietnam has a 950 kW connected electrical allowance and annual electricity planning of 3,400 MWh. At the selected annual output, this is approximately 71 kWh per tonne for preparation, forming, cooling and bulk handling. The allowance does not represent a wet-sludge drying plant.

Fresh-water planning is 480 m³ a year, covering 300 m³ of sanitary use and 180 m³ of controlled cleaning and services. Routine production uses accepted dry material and does not include continuous water addition to force wet sludge through the process. Any moisture adjustment follows the approved recipe and a measured balance.

Why Two Dedicated Forming Machines Are Selected

The refuse derived fuel pellet plant in Vietnam uses two dedicated machines, each selected around a 4 T/H duty on the approved industrial-residue blend. This choice provides the required combined rate. It is not based on transferring a wood-pellet or feed-pellet catalogue capacity to a different waste material.

Both machines need representative-material trials to establish output, product shape and working load. The combined cooler, screen and bulk-loading route are sized above the selected 8 T/H requirement. A successful forming trial alone does not prove that the downstream store can receive the product continuously.

Equipment Parameters for the Selected Material

Process equipment	Selected parameter	Quantity
Feed inspection and separation	Controlled receiving, screens and magnetic protection	One set
Primary size reducer	110 kW, for the accepted coarse fraction	One
Secondary preparation mill	160 kW; selected at least 10 T/H on the prepared blend	One
Weighed blending and buffer	At least 8 T/H stable combined supply	One set
Dedicated RDF forming machines	250 kW main drive each; selected 4 T/H per machine	Two
Active cooling	At least 8 T/H finished-product duty	One integrated set
Grading	Selected cylindrical fuel and controlled fines return	One set
Bulk dispatch system	At least 20 T/H	One route
Extraction, conveying and controls	Matched to each collection and transfer point	One package

The refuse derived fuel pellet plant in Vietnam includes supporting motors in its electrical schedule. Primary preparation does not receive every fine sawdust tonne unnecessarily. The operating sequence reflects material size, allowing suitable fine streams to bypass coarse reduction while retaining the necessary inspection and blending controls.

Daily finished output is 160 tonnes under the selected schedule. A 20 T/H bulk-loading route can transfer that quantity in eight net loading hours, subject to vehicle access and actual loading checks. The customer plans release, truck slots and empty-store access around that requirement. This gives the compact finished store a clear turnover role and allows industrial buyers to discuss their collection windows before regular supply begins.

The Material Route From Receipt to Bulk Fuel

The refuse derived fuel pellet plant in Vietnam follows a defined route: acceptance and separation, selective size reduction, weighed blending, controlled forming, active cooling, grading and bulk dispatch. Material rejected at acceptance leaves that route and remains segregated.

The selected system has no wet-sludge reception tank, dewatering press or thermal raw-material dryer. Those boundaries are stated in the equipment scope so the customer can compare quotations for the same incoming condition and finished-fuel duty.

What Operators Check Along the Route

Identify the incoming source

The receiving team records supplier, residue type, quantity and sampling status. Loads awaiting results remain on hold. Staff inspect for unsuitable materials and visible contamination, with the relevant chemical and fuel tests arranged through the quality programme.

Prepare only what needs reduction

Coarse fibre, bark and straw follow the appropriate cutting or size-reduction route. Suitable sawdust can bypass the primary machine. The team verifies the prepared size and fibre shape for the selected forming tools, rather than assuming one screen opening describes every incoming material.

Blend by measured mass

The approved streams enter the blending system in their stated proportions. Operators observe bridging and discharge consistency. A wet pocket or an unexpected density change is investigated before the feed rate is increased, because a stable motor current does not establish a stable recipe.

Form under the approved settings

Each dedicated machine operates at the recipe-specific setting established by trials. Temperature, load and product shape are monitored together. The plant does not depend on a universal melting temperature or chemical additive to make every industrial residue behave alike.

Cool before stockpiling

Active cooling reduces product temperature before fuel enters the finished store. Operators check for hot material and abnormal odour, and follow the approved response procedure when a concern appears. Warm fuel is not buried under a fresh stockpile merely to keep the forming machines running.

Grade and identify the dispatch

The screen removes fines and unsuitable pieces. Clean identified returns are limited by the approved procedure. The refuse derived fuel pellet plant in Vietnam connects each bulk dispatch with the blend record, production period and agreed fuel-quality results.

A Water Balance Without an Uncounted Dryer

The fresh-water allowance covers site services, not a routine 5,000 m³ production addition. At the refuse derived fuel pellet plant in Vietnam, the incoming 10–12% moisture condition is part of the purchasing specification. A wetter lot needs upstream preparation or a different process assessment before it is approved.

Sanitary wastewater and controlled cleaning drainage follow their appropriate site routes. Dusty floor material is removed before washing, with recovered material assessed by identity and contamination. Water used for cleaning is not automatically a reusable ingredient in the next fuel batch.

Moisture records connect receiving and dispatch. If incoming material consistently exceeds the approved window, the customer reviews procurement and drying requirements. Supplier approval and any process change follow the agreed incoming and finished-moisture specifications.

Checking the Electrical Supply Before Installation

The refuse derived fuel pellet plant in Vietnam has 500 kW of forming-machine main drives before preparation, fans and transfer equipment are counted. The 950 kW connected allowance therefore requires an industrial service assessment. The customer confirms available capacity, starting methods and protection with its electrical specialists and utility provider.

Annual electricity planning follows the scheduled 6,000 net processing hours. Drive loading varies because some material bypasses coarse preparation and forming load depends on the approved blend. Trial and operating records establish the energy requirement for each approved paper-residue blend.

Rotating Production Teams and Shared Support

Twenty roles support the refuse derived fuel pellet plant in Vietnam. Three rotating production teams of four account for twelve roles, with eight further roles covering receiving, dispatch, quality, maintenance and administration. The roster covers the two daily operating periods and planned service work.

The operator training programme includes source identification, feeder stability, hot-product response and safe isolation. Maintenance access is protected during normal material handling. A compact production building needs these routines as much as a larger plant, especially where combustible fibre and warm product are handled near stored stock.

From the Packing List to a Ready Installation Site

The shipping plan for the refuse derived fuel pellet plant in Vietnam identifies forming-machine weights, lifting points, preparation equipment and control cabinets. Southern Vietnamese port selection follows the actual site and freight booking. The customer arranges suitable unloading and inland transport from the confirmed gateway.

Before erection, the host site confirms foundations, external access, electrical supply, extraction positions and finished-product loading. Local waste acceptance, storage and industrial-fuel use requirements are assessed for the actual materials and receiving customers. The customer coordinates those operating approvals with the site preparation and acceptance programme.

Commissioning records the entire route with representative approved material. The checks include weighed input, source identity, output, electrical load, cooled-product condition, fines and dispatch capacity. RICHI’s support focuses on equipment integration and operator instruction within the agreed project responsibility plan.

Budget Scope for the Dry Industrial-Fibre Route

The equipment budget for the refuse derived fuel pellet plant in Vietnam is USD 315,000. The total project budget is USD 495,000, covering the selected machines, delivery allowances, installation, foundations, defined electrical integration, extraction and adaptation of usable host premises.

The basis excludes land purchase, a new building estate, upstream wet-sludge dewatering and thermal bulk drying. Major off-site utility reinforcement beyond the defined connection also requires separate identification. Buyers can therefore compare the RDF pelletizing equipment and the surrounding work on the same incoming-material basis.

The customer’s commercial assessment uses actual accepted-residue supply and industrial off-take agreements. Waste classification, product quality and customer permits affect whether a stream is usable. The equipment budget alone does not establish revenue or a payback period for an industrial waste fuel plant.
