    SHOOTING TARGET
    TECHNICAL FIELD The present disclosure relates to a shooting target comprising plant-based particles, lignin or a combination thereof. The present disclosure further relates to a method for producing a shooting target comprising plant-based particles, lignin or a combina- tion thereof. The present disclosure further relates to the use of the shooting target.
    BACKGROUND Shooting sports, including clay pigeon shooting or clay target shooting, are popular sporting activities in several countries. Due their popularity, an enormous amount of targets are being consumed annually. Conventional clay targets or clay pigeons, typically used for these sports, generally include non-biodegradable components, such as pitches, tars and other petroleum products which are used as binders for limestone-containing targets. These are also es- sential components for the limestone-containing tar- gets to strengthen the target so that it can be stored, shipped and launched without breaking. Howev- o er, these components are also very hazardous for the > health and the environment as they do not decompose O and may penetrate for example to the soil. The pH of n the field may further be changed which may affect the 9 30 whole ecosystem. Thus there remains a need to find = better and more sustainable options for the target © compositions.

    The method has the added 2 utility that it is suitable for several types of wood. 3 35 The wood may be considered as leftover wood from the N forest industry.
    Thus, the raw materials for production of the shooting targets with the method of the current application are inexpensive and easily available. In one embodiment, the shooting target consists of wood particles and lignin.
    5 In the context of this specification, the term "lignin” may refer to lignin originating from any suitable lignin source. Lignin is a complex natural polymer found in the cell walls of plants. Lignocellulosic biomass is typically nonedible plant material, including dedicated crops of wood and grass, and agro-forest residues. Lignocellulosic biomass is mainly composed of cellulose, hemicellulose, and lignin. It should be further noted that the wood particles itself include certain amounts of lignin.
    In one embodiment, the lignin is essentially pure lignin. By the expression “essentially pure lignin” should be understood as at least 70% pure lignin, or at least 80% pure lignin, or at least 90% pure lignin, or at least 95 % pure lignin, or at least 98% pure lignin. In one embodiment, the essentially pure lignin comprises at most 30%, or at most 20%, or at most 10%, or at most 10%, or at most 2 %, of other components and/or impurities.
    In one embodiment of the present invention the lignin is selected from a group consisting of kraft lignin, steam explosion lignin, Dbiorefinery lignin, supercritical separation lignin, hydrolysis = lignin, biomass originating lignin, lignin from N alkaline pulping process, lignin from soda process, = 30 lignin from organosolv pulping, lignin from an O enzymatic process, and any combinations thereof. In = one embodiment of the present invention, the lignin is c wood based lignin. The lignin can originate from 3 softwood, hardwood, annual plants or from any 3 35 combination thereof. In one embodiment, the lignin is "kraft lignin”. Kraft lignin may be isolated from black liquor obtained from the kraft pulping process used for wood pulping. The black liquor from the pulping process may comprise components from different softwood and hardwood species in various proportions. Kraft lignin may, for example, be Lineo™-type lignin.
    In one embodiment, the lignin is steam explosion lignin. Steam explosion may be a biomass pretreatment process. In this process, high pressure steam is applied on lignocellulosic material for a short period of time followed by sudden explosion leading to the fiberization of the biomass. Steam explosion may also refer to a pulping and extraction method which is applicable for wood and other organic material.
    In one embodiment, the biorefinery lignin refers to, unless otherwise stated, to lignin recovered from a refining facility or process converting biomass into fuels, chemicals and other materials.
    In one embodiment, the supercritical separation lignin refers to lignin which is separated from lignocellulosic material by supercritical fluid extraction. In this process, one component (lignin) is separated from another using supercritical fluids as the extracting solvent. Carbon dioxide (CO,) is the most used supercritical fluid, sometimes modified by co-solvents such as ethanol or methanol.
    = In one embodiment, the lignin originates from N a hydrolysis process. Lignin derived from the - 30 hydrolysis process can be recovered from paper-pulp or O wood-chemical processes.
    = In one embodiment, the lignin originates from c biomass. Lignin differs naturally in content and 2 composition between biomass materials at various 3 35 levels, e.g., between species, within species and between components (such as wood and bark), and is influenced by plant growth stage and environmental stress. In one embodiment, the lignin originates from an alkaline pulping process. This refers to an alkali process where biomass is liquefied with strong alkali followed by neutralization. Lignin is obtained via precipitation. In one embodiment, the lignin originates from a soda process, which refers to the traditional chemical pulping method where the fibrous material is heated in pressurized reactor in the presence of sodium hydroxide. In the process, lignin is separated from the cellulose and suspends into the liguid phase. The liguid phase, black liquor, due to the presence of lignin, is separated from the solid phase containing liberated cellulose.
    In one embodiment, the lignin is from organosolv pulping. Organosolv pulping refers to a pulping technique where organic solvent is used to solubilize lignin and hemicellulose. Organosolv processes aim to fractionate the lignocellulosic biomass as much as possible into individual major fractions. Organosclv lignin has generally a high purity level.
    In the context of this specification, the term “biodegradable” may refer to material which through a biological process is capable of decomposing = into carbon dioxide, water, and biomass.

    Standard targets are most commonly used.
    Their size may vary depending on whether an American or International competition is at stake.
    Midi targets may have a similar profile to the standard but are smaller in size.
    These targets may be faster than the standard types.
    Mini targets may be even smaller than midi targets.
    They may be suitable for more experienced = shooters.
    N Battue or duck targets may have a flat = 30 profile which may cause it to fly fast for a distance O and then roll and drop rapidly.
    They are often thrown = so that they initially appear edge on and may then c roll sideways as they fall to the ground. 2 Rabbit or auto rabbit or Jackrabbit targets 3 35 may have the same diameter as a standard but as the name implies, it may simulate a running rabbit.
    The target may be rolled along the ground, bucking and bouncing as it goes.
    In order to take this punishment the rabbit target may have a thick rim.
    Rocket targets may be heavy, thick-rimmed targets with the same diameter as the standard targets.
    They tend to slow down in flight less quickly than the standard targets. "ZZ" targets are special plastic targets, wherein the center part may have the diameter of a standard target whereas the outer part may be a propeller.

In skeet shooting targets may be thrown in singles and doubles from 2 trap houses situated about 40 meters apart, at opposite ends of a semicircular arc on which there are seven shooting positions. The targets are thrown at set trajectories and speeds. The main disciplines in this group are English skeet, Olympic skeet and American (NSSA) skeet. In trap shooting targets are thrown either as singles or doubles from one or more traps situated some 15 m in front of the shooter, and are generally going away from the firing point at varying speeds, angles and elevations. The most common disciplines in this group are Down-The-Line (DTL) Single Barrel, Double Rise, Automatic Ball Trap (ABT), Olympic Trap, Double Trap, Universal Trench, Helice (or 22). Sporting clays is an English Sporting discipline. In this discipline, targets are thrown in a great variety of trajectories, = angles, speeds, elevations and distances. The N discipline was originally devised to simulate live = 30 quarry shooting, hence some of the names commonly used O on sporting stands: springing teal, driven pheasant, = bolting rabbit, crossing pigeon, dropping duck, etc. c Disciplines in this group include English sporting, 2 international (FITASC) sporting, super sporting 3 35 sportrap, and Compak sporting. N The shooting target has the added utility of providing an environmentally sound option for the current shooting targets without increasing the costs of the targets. Further, the present method has the added utility of providing a simple and inexpensive manner for the preparation of shooting targets.

    The description below discloses some embodiments in such a detail that a person skilled in the art is able to utilize the embodiments based on the disclosure. Not all steps or features of the embodiments are discussed in detail, as many of the steps or features will be obvious for the person skilled in the art based on this specification.
    Example 1 — Producing shooting targets In this example shooting targets were produced in the following manner: Firstly, a mixture comprising pine wood particles and lignin was formed. The ratio of wood particles to lignin in the mixture was 40/60 based on their weights. The average particle size of the wood particles was 0.6 - 1 mm. The mixture was stored in order to stabilize the relative humidity thereof to a value of 65 %. = Then samples of 100 - 120 g of the mixture N were placed in molds having the form of a shooting = 30 target with a predetermined size and shape. Then the O same were pressed in the molds by using a pressing = force of 10 kN while the samples were simultaneously c heated to a temperature of 80 °C. The pressing was 3 continued for 5-7 minutes after which the molds were 3 35 opened and shooting targets of a predetermined shape and size were formed. The formed shooting targets were then coated with a protective layer of lime paint such that the whole outer surface of the shooting target was covered. When the protective layer had been allowed to dry the shooting targets were packed for transportation.
    Following the above described procedure the following shooting targets were produced by varying the above described parameters in the following manners: Sample number Ratio of lignin | Temperature to wood | during the particles pressing step (weight-%) (°C) 6 | 20/80 | so | a | 60440 | 0 so | 09 | sje | so | n | 20/80 | 0 80 | a | ao/e0 | 0 80 | 13 | eo/a40 | 0 80 | > a | so/20 | 0 | S ws | 2000 | 80 | O 10 n The density of the formed shooting targets 7 were calculated by measuring the sized of the shooting = targets with a slide gauge and by weighing the same, O after which the masses and volumes were calculated. LO 15 The volumes were calculated by the formula for DO calculating the volume of a cylinder, i.e. N volume=area*height (V=A*h). Also the maximum strength of the shooting targets were measured by pressing the shooting target until it breaks into pieces.
    The results are presented in the below table Mixture number Density of the | Maximum strength shooting target | of the shooting (kg/m ) target (N) 2 | 0 | | a | 980 | 85 | 0s | 060 | 66 | 09 EEE IEN
    From the above results, it can be concluded that the formed shooting targets were suitable to be used as shooting targets for e.g. skeet shooting etc. o > 10 It is obvious to a person skilled in the art O that with the advancement of technology, the basic n idea may be implemented in various ways.
    The 7 embodiments are thus not limited to the examples = described above; instead they may vary within the O 15 scope of the claims.
